BCDEDIT - Boot Configuration Data Store Editor
The Bcdedit.exe command-line tool modifies the boot configuration data store.
The boot configuration data store contains boot configuration parameters and
controls how the operating system is booted. These parameters were previously
in the Boot.ini file (in BIOS-based operating systems) or in the nonvolatile
RAM entries (in Extensible Firmware Interface-based operating systems). You can
use Bcdedit.exe to add, delete, edit, and append entries in the boot
configuration data store.
For detailed command and option information, type bcdedit.exe /? <command>. For
example, to display detailed information about the /createstore command, type:
bcdedit.exe /? /createstore
For an alphabetical list of topics in this help file, run "bcdedit /? TOPICS".
Commands that operate on a store
================================
/createstore Creates a new and empty boot configuration data store.
/export Exports the contents of the system store to a file. This file
can be used later to restore the state of the system store.
/import Restores the state of the system store using a backup file
created with the /export command.
/sysstore Sets the system store device (only affects EFI systems, does
not persist across reboots, and is only used in cases where
the system store device is ambiguous).
Commands that operate on entries in a store
===========================================
/copy Makes copies of entries in the store.
/create Creates new entries in the store.
/delete Deletes entries from the store.
/mirror Creates mirror of entries in the store.
Run bcdedit /? ID for information about identifiers used by these commands.
Commands that operate on entry options
======================================
/deletevalue Deletes entry options from the store.
/set Sets entry option values in the store.
Run bcdedit /? TYPES for a list of datatypes used by these commands.
Run bcdedit /? FORMATS for a list of valid data formats.
Commands that control output
============================
/enum Lists entries in the store.
/v Command-line option that displays entry identifiers in full,
rather than using names for well-known identifiers.
Use /v by itself as a command to display entry identifiers
in full for the ACTIVE type.
Running "bcdedit" by itself is equivalent to running "bcdedit /enum ACTIVE".
Commands that control the boot manager
======================================
/bootsequence Sets the one-time boot sequence for the boot manager.
/default Sets the default entry that the boot manager will use.
/displayorder Sets the order in which the boot manager displays the
multiboot menu.
/timeout Sets the boot manager time-out value.
/toolsdisplayorder Sets the order in which the boot manager displays
the tools menu.
Commands that control Emergency Management Services for a boot application
==========================================================================
/bootems Enables or disables Emergency Management Services
for a boot application.
/ems Enables or disables Emergency Management Services for an
operating system entry.
/emssettings Sets the global Emergency Management Services parameters.
Command that control debugging
==============================
/bootdebug Enables or disables boot debugging for a boot application.
/dbgsettings Sets the global debugger parameters.
/debug Enables or disables kernel debugging for an operating system
entry.
/hypervisorsettings Sets the hypervisor parameters.
Sets or Clears Extended CTRL+C checking on DOS system This is present for Compatibility with DOS systems. It has no effect under Windows. If Command Extensions are enabled, and running on the Windows platform, then the BREAK command will enter a hard coded breakpoint if being debugged by a debugger.
NOTE: Cacls is now deprecated, please use Icacls.
Displays or modifies access control lists (ACLs) of files
CACLS filename [/T] [/M] [/L] [/S[:SDDL]] [/E] [/C] [/G user:perm]
[/R user [...]] [/P user:perm [...]] [/D user [...]]
filename Displays ACLs.
/T Changes ACLs of specified files in
the current directory and all subdirectories.
/L Work on the Symbolic Link itself versus the target
/M Changes ACLs of volumes mounted to a directory
/S Displays the SDDL string for the DACL.
/S:SDDL Replaces the ACLs with those specified in the SDDL string
(not valid with /E, /G, /R, /P, or /D).
/E Edit ACL instead of replacing it.
/C Continue on access denied errors.
/G user:perm Grant specified user access rights.
Perm can be: R Read
W Write
C Change (write)
F Full control
/R user Revoke specified user's access rights (only valid with /E).
/P user:perm Replace specified user's access rights.
Perm can be: N None
R Read
W Write
C Change (write)
F Full control
/D user Deny specified user access.
Wildcards can be used to specify more than one file in a command.
You can specify more than one user in a command.
Abbreviations:
CI - Container Inherit.
The ACE will be inherited by directories.
OI - Object Inherit.
The ACE will be inherited by files.
IO - Inherit Only.
The ACE does not apply to the current file/directory.
ID - Inherited.
The ACE was inherited from the parent directory's ACL.
Calls one batch program from another.
CALL [drive:][path]filename [batch-parameters]
batch-parameters Specifies any command-line information required by the
batch program.
If Command Extensions are enabled CALL changes as follows:
CALL command now accepts labels as the target of the CALL. The syntax
is:
CALL :label arguments
A new batch file context is created with the specified arguments and
control is passed to the statement after the label specified. You must
"exit" twice by reaching the end of the batch script file twice. The
first time you read the end, control will return to just after the CALL
statement. The second time will exit the batch script. Type GOTO /?
for a description of the GOTO :EOF extension that will allow you to
"return" from a batch script.
In addition, expansion of batch script argument references (%0, %1,
etc.) have been changed as follows:
%* in a batch script refers to all the arguments (e.g. %1 %2 %3
%4 %5 ...)
Substitution of batch parameters (%n) has been enhanced. You can
now use the following optional syntax:
%~1 - expands %1 removing any surrounding quotes (")
%~f1 - expands %1 to a fully qualified path name
%~d1 - expands %1 to a drive letter only
%~p1 - expands %1 to a path only
%~n1 - expands %1 to a file name only
%~x1 - expands %1 to a file extension only
%~s1 - expanded path contains short names only
%~a1 - expands %1 to file attributes
%~t1 - expands %1 to date/time of file
%~z1 - expands %1 to size of file
%~$PATH:1 - searches the directories listed in the PATH
environment variable and expands %1 to the fully
qualified name of the first one found. If the
environment variable name is not defined or the
file is not found by the search, then this
modifier expands to the empty string
The modifiers can be combined to get compound results:
%~dp1 - expands %1 to a drive letter and path only
%~nx1 - expands %1 to a file name and extension only
%~dp$PATH:1 - searches the directories listed in the PATH
environment variable for %1 and expands to the
drive letter and path of the first one found.
%~ftza1 - expands %1 to a DIR like output line
In the above examples %1 and PATH can be replaced by other
valid values. The %~ syntax is terminated by a valid argument
number. The %~ modifiers may not be used with %*
Displays the name of or changes the current directory.
CHDIR [/D] [drive:][path]
CHDIR [..]
CD [/D] [drive:][path]
CD [..]
.. Specifies that you want to change to the parent directory.
Type CD drive: to display the current directory in the specified drive.
Type CD without parameters to display the current drive and directory.
Use the /D switch to change current drive in addition to changing current
directory for a drive.
If Command Extensions are enabled CHDIR changes as follows:
The current directory string is converted to use the same case as
the on disk names. So CD C:\TEMP would actually set the current
directory to C:\Temp if that is the case on disk.
CHDIR command does not treat spaces as delimiters, so it is possible to
CD into a subdirectory name that contains a space without surrounding
the name with quotes. For example:
cd \winnt\profiles\username\programs\start menu
is the same as:
cd "\winnt\profiles\username\programs\start menu"
which is what you would have to type if extensions were disabled.
Displays or sets the active code page number. CHCP [nnn] nnn Specifies a code page number. Type CHCP without a parameter to display the active code page number.
Displays the name of or changes the current directory.
CHDIR [/D] [drive:][path]
CHDIR [..]
CD [/D] [drive:][path]
CD [..]
.. Specifies that you want to change to the parent directory.
Type CD drive: to display the current directory in the specified drive.
Type CD without parameters to display the current drive and directory.
Use the /D switch to change current drive in addition to changing current
directory for a drive.
If Command Extensions are enabled CHDIR changes as follows:
The current directory string is converted to use the same case as
the on disk names. So CD C:\TEMP would actually set the current
directory to C:\Temp if that is the case on disk.
CHDIR command does not treat spaces as delimiters, so it is possible to
CD into a subdirectory name that contains a space without surrounding
the name with quotes. For example:
cd \winnt\profiles\username\programs\start menu
is the same as:
cd "\winnt\profiles\username\programs\start menu"
which is what you would have to type if extensions were disabled.
Checks a disk and displays a status report.
CHKDSK [volume[[path]filename]]] [/F] [/V] [/R] [/X] [/I] [/C] [/L[:size]] [/B] [/scan] [/spotfix]
volume Specifies the drive letter (followed by a colon),
mount point, or volume name.
filename FAT/FAT32 only: Specifies the files to check for
fragmentation.
/F Fixes errors on the disk.
/V On FAT/FAT32: Displays the full path and name of every
file on the disk.
On NTFS: Displays cleanup messages if any.
/R Locates bad sectors and recovers readable information
(implies /F, when /scan not specified).
/L:size NTFS only: Changes the log file size to the specified
number of kilobytes. If size is not specified, displays
current size.
/X Forces the volume to dismount first if necessary.
All opened handles to the volume would then be invalid
(implies /F).
/I NTFS only: Performs a less vigorous check of index
entries.
/C NTFS only: Skips checking of cycles within the folder
structure.
/B NTFS only: Re-evaluates bad clusters on the volume
(implies /R)
/scan NTFS only: Runs a online scan on the volume
/forceofflinefix NTFS only: (Must be used with "/scan")
Bypass all online repair; all defects found
are queued for offline repair (i.e. "chkdsk /spotfix").
/perf NTFS only: (Must be used with "/scan")
Uses more system resources to complete a scan as fast as
possible. This may have a negative performance impact on
other tasks running on the system.
/spotfix NTFS only: Runs spot fixing on the volume
/sdcleanup NTFS only: Garbage collect unneeded security descriptor
data (implies /F).
/offlinescanandfix Runs an offline scan and fix on the volume.
The /I or /C switch reduces the amount of time required to run Chkdsk by
skipping certain checks of the volume.
Displays or modifies the checking of disk at boot time.
CHKNTFS volume [...]
CHKNTFS /D
CHKNTFS /T[:time]
CHKNTFS /X volume [...]
CHKNTFS /C volume [...]
volume Specifies the drive letter (followed by a colon),
mount point, or volume name.
/D Restores the machine to the default behavior; all drives are
checked at boot time and chkdsk is run on those that are
dirty.
/T:time Changes the AUTOCHK initiation countdown time to the
specified amount of time in seconds. If time is not
specified, displays the current setting.
/X Excludes a drive from the default boot-time check. Excluded
drives are not accumulated between command invocations.
/C Schedules a drive to be checked at boot time; chkdsk will run
if the drive is dirty.
If no switches are specified, CHKNTFS will display if the specified drive is
dirty or scheduled to be checked on next reboot.
CHOICE [/C choices] [/N] [/CS] [/T timeout /D choice] [/M text]
Description:
This tool allows users to select one item from a list
of choices and returns the index of the selected choice.
Parameter List:
/C choices Specifies the list of choices to be created.
Default list is "YN".
/N Hides the list of choices in the prompt.
The message before the prompt is displayed
and the choices are still enabled.
/CS Enables case-sensitive choices to be selected.
By default, the utility is case-insensitive.
/T timeout The number of seconds to pause before a default
choice is made. Acceptable values are from 0 to
9999. If 0 is specified, there will be no pause
and the default choice is selected.
/D choice Specifies the default choice after nnnn seconds.
Character must be in the set of choices specified
by /C option and must also specify nnnn with /T.
/M text Specifies the message to be displayed before
the prompt. If not specified, the utility
displays only a prompt.
/? Displays this help message.
NOTE:
The ERRORLEVEL environment variable is set to the index of the
key that was selected from the set of choices. The first choice
listed returns a value of 1, the second a value of 2, and so on.
If the user presses a key that is not a valid choice, the tool
sounds a warning beep. If tool detects an error condition,
it returns an ERRORLEVEL value of 255. If the user presses
CTRL+BREAK or CTRL+C, the tool returns an ERRORLEVEL value
of 0. When you use ERRORLEVEL parameters in a batch program, list
them in decreasing order.
Examples:
CHOICE /?
CHOICE /C YNC /M "Press Y for Yes, N for No or C for Cancel."
CHOICE /T 10 /C ync /CS /D y
CHOICE /C ab /M "Select a for option 1 and b for option 2."
CHOICE /C ab /N /M "Select a for option 1 and b for option 2."
Clears the screen. CLS
Starts a new instance of the Windows command interpreter
CMD [/A | /U] [/Q] [/D] [/E:ON | /E:OFF] [/F:ON | /F:OFF] [/V:ON | /V:OFF]
[[/S] [/C | /K] string]
/C Carries out the command specified by string and then terminates
/K Carries out the command specified by string but remains
/S Modifies the treatment of string after /C or /K (see below)
/Q Turns echo off
/D Disable execution of AutoRun commands from registry (see below)
/A Causes the output of internal commands to a pipe or file to be ANSI
/U Causes the output of internal commands to a pipe or file to be
Unicode
/T:fg Sets the foreground/background colors (see COLOR /? for more info)
/E:ON Enable command extensions (see below)
/E:OFF Disable command extensions (see below)
/F:ON Enable file and directory name completion characters (see below)
/F:OFF Disable file and directory name completion characters (see below)
/V:ON Enable delayed environment variable expansion using ! as the
delimiter. For example, /V:ON would allow !var! to expand the
variable var at execution time. The var syntax expands variables
at input time, which is quite a different thing when inside of a FOR
loop.
/V:OFF Disable delayed environment expansion.
Note that multiple commands separated by the command separator '&&'
are accepted for string if surrounded by quotes. Also, for compatibility
reasons, /X is the same as /E:ON, /Y is the same as /E:OFF and /R is the
same as /C. Any other switches are ignored.
If /C or /K is specified, then the remainder of the command line after
the switch is processed as a command line, where the following logic is
used to process quote (") characters:
1. If all of the following conditions are met, then quote characters
on the command line are preserved:
- no /S switch
- exactly two quote characters
- no special characters between the two quote characters,
where special is one of: &<>()@ˆ|
- there are one or more whitespace characters between the
two quote characters
- the string between the two quote characters is the name
of an executable file.
2. Otherwise, old behavior is to see if the first character is
a quote character and if so, strip the leading character and
remove the last quote character on the command line, preserving
any text after the last quote character.
If /D was NOT specified on the command line, then when CMD.EXE starts, it
looks for the following REG_SZ/REG_EXPAND_SZ registry variables, and if
either or both are present, they are executed first.
HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\AutoRun
and/or
HKEY_CURRENT_USER\Software\Microsoft\Command Processor\AutoRun
Command Extensions are enabled by default. You may also disable
extensions for a particular invocation by using the /E:OFF switch. You
can enable or disable extensions for all invocations of CMD.EXE on a
machine and/or user logon session by setting either or both of the
following REG_DWORD values in the registry using REGEDIT.EXE:
HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\EnableExtensions
and/or
HKEY_CURRENT_USER\Software\Microsoft\Command Processor\EnableExtensions
to either 0x1 or 0x0. The user specific setting takes precedence over
the machine setting. The command line switches take precedence over the
registry settings.
In a batch file, the SETLOCAL ENABLEEXTENSIONS or DISABLEEXTENSIONS arguments
takes precedence over the /E:ON or /E:OFF switch. See SETLOCAL /? for details.
The command extensions involve changes and/or additions to the following
commands:
DEL or ERASE
COLOR
CD or CHDIR
MD or MKDIR
PROMPT
PUSHD
POPD
SET
SETLOCAL
ENDLOCAL
IF
FOR
CALL
SHIFT
GOTO
START (also includes changes to external command invocation)
ASSOC
FTYPE
To get specific details, type commandname /? to view the specifics.
Delayed environment variable expansion is NOT enabled by default. You
can enable or disable delayed environment variable expansion for a
particular invocation of CMD.EXE with the /V:ON or /V:OFF switch. You
can enable or disable delayed expansion for all invocations of CMD.EXE on a
machine and/or user logon session by setting either or both of the
following REG_DWORD values in the registry using REGEDIT.EXE:
HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\DelayedExpansion
and/or
HKEY_CURRENT_USER\Software\Microsoft\Command Processor\DelayedExpansion
to either 0x1 or 0x0. The user specific setting takes precedence over
the machine setting. The command line switches take precedence over the
registry settings.
In a batch file the SETLOCAL ENABLEDELAYEDEXPANSION or DISABLEDELAYEDEXPANSION
arguments takes precedence over the /V:ON or /V:OFF switch. See SETLOCAL /?
for details.
If delayed environment variable expansion is enabled, then the exclamation
character can be used to substitute the value of an environment variable
at execution time.
You can enable or disable file name completion for a particular
invocation of CMD.EXE with the /F:ON or /F:OFF switch. You can enable
or disable completion for all invocations of CMD.EXE on a machine and/or
user logon session by setting either or both of the following REG_DWORD
values in the registry using REGEDIT.EXE:
HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\CompletionChar
HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\PathCompletionChar
and/or
HKEY_CURRENT_USER\Software\Microsoft\Command Processor\CompletionChar
HKEY_CURRENT_USER\Software\Microsoft\Command Processor\PathCompletionChar
with the hex value of a control character to use for a particular
function (e.g. 0x4 is Ctrl-D and 0x6 is Ctrl-F). The user specific
settings take precedence over the machine settings. The command line
switches take precedence over the registry settings.
If completion is enabled with the /F:ON switch, the two control
characters used are Ctrl-D for directory name completion and Ctrl-F for
file name completion. To disable a particular completion character in
the registry, use the value for space (0x20) as it is not a valid
control character.
Completion is invoked when you type either of the two control
characters. The completion function takes the path string to the left
of the cursor appends a wild card character to it if none is already
present and builds up a list of paths that match. It then displays the
first matching path. If no paths match, it just beeps and leaves the
display alone. Thereafter, repeated pressing of the same control
character will cycle through the list of matching paths. Pressing the
Shift key with the control character will move through the list
backwards. If you edit the line in any way and press the control
character again, the saved list of matching paths is discarded and a new
one generated. The same occurs if you switch between file and directory
name completion. The only difference between the two control characters
is the file completion character matches both file and directory names,
while the directory completion character only matches directory names.
If file completion is used on any of the built in directory commands
(CD, MD or RD) then directory completion is assumed.
The completion code deals correctly with file names that contain spaces
or other special characters by placing quotes around the matching path.
Also, if you back up, then invoke completion from within a line, the
text to the right of the cursor at the point completion was invoked is
discarded.
The special characters that require quotes are:
<space>
&()[]{}ˆ=;!'+,`~
Sets the default console foreground and background colors.
COLOR [attr]
attr Specifies color attribute of console output
Color attributes are specified by TWO hex digits -- the first
corresponds to the background; the second the foreground. Each digit
can be any of the following values:
0 = Black 8 = Gray
1 = Blue 9 = Light Blue
2 = Green A = Light Green
3 = Aqua B = Light Aqua
4 = Red C = Light Red
5 = Purple D = Light Purple
6 = Yellow E = Light Yellow
7 = White F = Bright White
If no argument is given, this command restores the color to what it was
when CMD.EXE started. This value either comes from the current console
window, the /T command line switch or from the DefaultColor registry
value.
The COLOR command sets ERRORLEVEL to 1 if an attempt is made to execute
the COLOR command with a foreground and background color that are the
same.
Example: "COLOR fc" produces light red on bright white
Compares the contents of two files or sets of files. COMP [data1] [data2] [/D] [/A] [/L] [/N=number] [/C] [/OFF[LINE]] data1 Specifies location and name(s) of first file(s) to compare. data2 Specifies location and name(s) of second files to compare. /D Displays differences in decimal format. /A Displays differences in ASCII characters. /L Displays line numbers for differences. /N=number Compares only the first specified number of lines in each file. /C Disregards case of ASCII letters when comparing files. /OFF[LINE] Do not skip files with offline attribute set. To compare sets of files, use wildcards in data1 and data2 parameters.
Displays or alters the compression of files on NTFS partitions.
COMPACT [/C | /U] [/S[:dir]] [/A] [/I] [/F] [/Q] [filename [...]]
/C Compresses the specified files. Directories will be marked
so that files added afterward will be compressed.
/U Uncompresses the specified files. Directories will be marked
so that files added afterward will not be compressed.
/S Performs the specified operation on files in the given
directory and all subdirectories. Default "dir" is the
current directory.
/A Displays files with the hidden or system attributes. These
files are omitted by default.
/I Continues performing the specified operation even after errors
have occurred. By default, COMPACT stops when an error is
encountered.
/F Forces the compress operation on all specified files, even
those which are already compressed. Already-compressed files
are skipped by default.
/Q Reports only the most essential information.
filename Specifies a pattern, file, or directory.
Used without parameters, COMPACT displays the compression state of
the current directory and any files it contains. You may use multiple
filenames and wildcards. You must put spaces between multiple
parameters.
Converts a FAT volume to NTFS.
CONVERT volume /FS:NTFS [/V] [/CvtArea:filename] [/NoSecurity] [/X]
volume Specifies the drive letter (followed by a colon),
mount point, or volume name.
/FS:NTFS Specifies that the volume will be converted to NTFS.
/V Specifies that Convert will be run in verbose mode.
/CvtArea:filename
Specifies a contiguous file in the root directory

"hello there" in file x.y.
Regular expression quick reference:
. Wildcard: any character
* Repeat: zero or more occurrences of previous character or class
ˆ Line position: beginning of line
$ Line position: end of line

[ˆclass] Inverse class: any one character not in set
[x-y] Range: any characters within the specified range
\x Escape: literal use of metacharacter x
\<xyz Word position: beginning of word
xyz\> Word position: end of word
For full information on FINDSTR regular expressions refer to the online Command
Reference.
Runs a specified command for each file in a set of files.
FOR %variable IN (set) DO command [command-parameters]
%variable Specifies a single letter replaceable parameter.
(set) Specifies a set of one or more files. Wildcards may be used.
command Specifies the command to carry out for each file.
command-parameters
Specifies parameters or switches for the specified command.
To use the FOR command in a batch program, specify %%variable instead
of %variable. Variable names are case sensitive, so %i is different
from %I.
If Command Extensions are enabled, the following additional
forms of the FOR command are supported:
FOR /D %variable IN (set) DO command [command-parameters]
If set contains wildcards, then specifies to match against directory
names instead of file names.
FOR /R [[drive:]path] %variable IN (set) DO command [command-parameters]
Walks the directory tree rooted at [drive:]path, executing the FOR
statement in each directory of the tree. If no directory
specification is specified after /R then the current directory is
assumed. If set is just a single period (.) character then it
will just enumerate the directory tree.
FOR /L %variable IN (start,step,end) DO command [command-parameters]
The set is a sequence of numbers from start to end, by step amount.
So (1,1,5) would generate the sequence 1 2 3 4 5 and (5,-1,1) would
generate the sequence (5 4 3 2 1)
FOR /F ["options"] %variable IN (file-set) DO command [command-parameters]
FOR /F ["options"] %variable IN ("string") DO command [command-parameters]
FOR /F ["options"] %variable IN ('command') DO command [command-parameters]
or, if usebackq option present:
FOR /F ["options"] %variable IN (file-set) DO command [command-parameters]
FOR /F ["options"] %variable IN ('string') DO command [command-parameters]
FOR /F ["options"] %variable IN (`command`) DO command [command-parameters]
file-set is one or more file names. Each file is opened, read
and processed before going on to the next file in file-set.
Processing consists of reading in the file, breaking it up into
individual lines of text and then parsing each line into zero or
more tokens. The body of the for loop is then called with the
variable value(s) set to the found token string(s). By default, /F
passes the first blank separated token from each line of each file.
Blank lines are skipped. You can override the default parsing
behavior by specifying the optional "options" parameter. This
is a quoted string which contains one or more keywords to specify
different parsing options. The keywords are:
eol=c - specifies an end of line comment character
(just one)
skip=n - specifies the number of lines to skip at the
beginning of the file.
delims=xxx - specifies a delimiter set. This replaces the
default delimiter set of space and tab.
tokens=x,y,m-n - specifies which tokens from each line are to
be passed to the for body for each iteration.
This will cause additional variable names to
be allocated. The m-n form is a range,
specifying the mth through the nth tokens. If
the last character in the tokens= string is an
asterisk, then an additional variable is
allocated and receives the remaining text on
the line after the last token parsed.
usebackq - specifies that the new semantics are in force,
where a back quoted string is executed as a
command and a single quoted string is a
literal string command and allows the use of
double quotes to quote file names in
file-set.
Some examples might help:
FOR /F "eol=; tokens=2,3* delims=, " %i in (myfile.txt) do @echo %i %j %k
would parse each line in myfile.txt, ignoring lines that begin with
a semicolon, passing the 2nd and 3rd token from each line to the for
body, with tokens delimited by commas and/or spaces. Notice the for
body statements reference %i to get the 2nd token, %j to get the
3rd token, and %k to get all remaining tokens after the 3rd. For
file names that contain spaces, you need to quote the filenames with
double quotes. In order to use double quotes in this manner, you also
need to use the usebackq option, otherwise the double quotes will be
interpreted as defining a literal string to parse.
%i is explicitly declared in the for statement and the %j and %k
are implicitly declared via the tokens= option. You can specify up
to 26 tokens via the tokens= line, provided it does not cause an
attempt to declare a variable higher than the letter 'z' or 'Z'.
Remember, FOR variables are single-letter, case sensitive, global,
and you can't have more than 52 total active at any one time.
You can also use the FOR /F parsing logic on an immediate string, by
making the file-set between the parenthesis a quoted string,
using single quote characters. It will be treated as a single line
of input from a file and parsed.
Finally, you can use the FOR /F command to parse the output of a
command. You do this by making the file-set between the
parenthesis a back quoted string. It will be treated as a command
line, which is passed to a child CMD.EXE and the output is captured
into memory and parsed as if it was a file. So the following
example:
FOR /F "usebackq delims==" %i IN (`set`) DO @echo %i
would enumerate the environment variable names in the current
environment.
In addition, substitution of FOR variable references has been enhanced.
You can now use the following optional syntax:
%~I - expands %I removing any surrounding quotes (")
%~fI - expands %I to a fully qualified path name
%~dI - expands %I to a drive letter only
%~pI - expands %I to a path only
%~nI - expands %I to a file name only
%~xI - expands %I to a file extension only
%~sI - expanded path contains short names only
%~aI - expands %I to file attributes of file
%~tI - expands %I to date/time of file
%~zI - expands %I to size of file
%~$PATH:I - searches the directories listed in the PATH
environment variable and expands %I to the
fully qualified name of the first one found.
If the environment variable name is not
defined or the file is not found by the
search, then this modifier expands to the
empty string
The modifiers can be combined to get compound results:
%~dpI - expands %I to a drive letter and path only
%~nxI - expands %I to a file name and extension only
%~fsI - expands %I to a full path name with short names only
%~dp$PATH:I - searches the directories listed in the PATH
environment variable for %I and expands to the
drive letter and path of the first one found.
%~ftzaI - expands %I to a DIR like output line
In the above examples %I and PATH can be replaced by other valid
values. The %~ syntax is terminated by a valid FOR variable name.
Picking upper case variable names like %I makes it more readable and
avoids confusion with the modifiers, which are not case sensitive.

FORMAT volume [/V:label] [/Q] [/P:passes]
FORMAT volume [/Q]
volume Specifies the drive letter (followed by a colon),
mount point, or volume name.
/FS:filesystem Specifies the type of the file system (FAT, FAT32, exFAT,
NTFS, UDF).
/V:label Specifies the volume label.
/Q Performs a quick format. Note that this switch overrides /P.
/C NTFS only: Files created on the new volume will be compressed
by default.
/X Forces the volume to dismount first if necessary. All opened
handles to the volume would no longer be valid.
/R:revision UDF only: Forces the format to a specific UDF version
(1.02, 1.50, 2.00, 2.01, 2.50). The default
revision is 2.01.
/D UDF 2.50 only: Metadata will be duplicated.
/L NTFS Only: Use large size file records.
By default, the volume will be formatted with small size file
records.
/A:size Overrides the default allocation unit size. Default settings
are strongly recommended for general use.
NTFS supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K.
FAT supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K,
(128K, 256K for sector size > 512 bytes).
FAT32 supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K,
(128K, 256K for sector size > 512 bytes).
exFAT supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K,
128K, 256K, 512K, 1M, 2M, 4M, 8M, 16M, 32M.
Note that the FAT and FAT32 files systems impose the
following restrictions on the number of clusters on a volume:
FAT: Number of clusters <= 65526
FAT32: 65526 < Number of clusters < 4177918
Format will immediately stop processing if it decides that
the above requirements cannot be met using the specified
cluster size.
NTFS compression is not supported for allocation unit sizes
above 4096.
/F:size Specifies the size of the floppy disk to format (1.44)
/T:tracks Specifies the number of tracks per disk side.
/N:sectors Specifies the number of sectors per track.
/P:count Zero every sector on the volume. After that, the volume
will be overwritten "count" times using a different
random number each time. If "count" is zero, no additional
overwrites are made after zeroing every sector. This switch
is ignored when /Q is specified.
/S:state Specifies support for short filenames (enable, disable)
Short names are disabled by default

Displays or modifies file types used in file extension associations
FTYPE [fileType[=[openCommandString]]]
fileType Specifies the file type to examine or change
openCommandString Specifies the open command to use when launching files
of this type.
Type FTYPE without parameters to display the current file types that
have open command strings defined. FTYPE is invoked with just a file
type, it displays the current open command string for that file type.
Specify nothing for the open command string and the FTYPE command will
delete the open command string for the file type. Within an open
command string %0 or %1 are substituted with the file name being
launched through the assocation. %* gets all the parameters and %2
gets the 1st parameter, %3 the second, etc. %~n gets all the remaining
parameters starting with the nth parameter, where n may be between 2 and 9,
inclusive. For example:
ASSOC .pl=PerlScript
FTYPE PerlScript=perl.exe %1 %*
would allow you to invoke a Perl script as follows:
script.pl 1 2 3
If you want to eliminate the need to type the extensions, then do the
following:
set PATHEXT=.pl;%PATHEXT%
and the script could be invoked as follows:
script 1 2 3
Directs cmd.exe to a labeled line in a batch program. GOTO label label Specifies a text string used in the batch program as a label. You type a label on a line by itself, beginning with a colon. If Command Extensions are enabled GOTO changes as follows: GOTO command now accepts a target label of :EOF which transfers control to the end of the current batch script file. This is an easy way to exit a batch script file without defining a label. Type CALL /? for a description of extensions to the CALL command that make this feature useful.

[/setintegritylevel Level:policy[...]]
/grant[:r] Sid:perm grants the specified user access rights. With :r,
the permissions replace any previously granted explicit permissions.
Without :r, the permissions are added to any previously granted
explicit permissions.
/deny Sid:perm explicitly denies the specified user access rights.
An explicit deny ACE is added for the stated permissions and
the same permissions in any explicit grant are removed.
/remove[:[g|d]] Sid removes all occurrences of Sid in the ACL. With
:g, it removes all occurrences of granted rights to that Sid. With
:d, it removes all occurrences of denied rights to that Sid.
/setintegritylevel [(CI)(OI)]Level explicitly adds an integrity
ACE to all matching files. The level is to be specified as one
of:
L[ow]
M[edium]
H[igh]
Inheritance options for the integrity ACE may precede the level
and are applied only to directories.
/inheritance:e|d|r
e - enables inheritance
d - disables inheritance and copy the ACEs
r - remove all inherited ACEs
Note:
Sids may be in either numerical or friendly name form. If a numerical
form is given, affix a * to the start of the SID.
/T indicates that this operation is performed on all matching
files/directories below the directories specified in the name.
/C indicates that this operation will continue on all file errors.
Error messages will still be displayed.
/L indicates that this operation is performed on a symbolic link
itself versus its target.
/Q indicates that icacls should suppress success messages.
ICACLS preserves the canonical ordering of ACE entries:
Explicit denials
Explicit grants
Inherited denials
Inherited grants
perm is a permission mask and can be specified in one of two forms:
a sequence of simple rights:
N - no access
F - full access
M - modify access

Performs conditional processing in batch programs.
IF [NOT] ERRORLEVEL number command
IF [NOT] string1==string2 command
IF [NOT] EXIST filename command
NOT Specifies that Windows should carry out
the command only if the condition is false.
ERRORLEVEL number Specifies a true condition if the last program run
returned an exit code equal to or greater than the number
specified.
string1==string2 Specifies a true condition if the specified text strings
match.
EXIST filename Specifies a true condition if the specified filename
exists.
command Specifies the command to carry out if the condition is
met. Command can be followed by ELSE command which
will execute the command after the ELSE keyword if the
specified condition is FALSE
The ELSE clause must occur on the same line as the command after the IF. For
example:
IF EXIST filename. (
del filename.
) ELSE (
echo filename. missing.
)
The following would NOT work because the del command needs to be terminated
by a newline:
IF EXIST filename. del filename. ELSE echo filename. missing
Nor would the following work, since the ELSE command must be on the same line
as the end of the IF command:
IF EXIST filename. del filename.
ELSE echo filename. missing
The following would work if you want it all on one line:
IF EXIST filename. (del filename.) ELSE echo filename. missing
If Command Extensions are enabled IF changes as follows:
IF [/I] string1 compare-op string2 command
IF CMDEXTVERSION number command
IF DEFINED variable command
where compare-op may be one of:
EQU - equal
NEQ - not equal
LSS - less than
LEQ - less than or equal
GTR - greater than
GEQ - greater than or equal
and the /I switch, if specified, says to do case insensitive string
compares. The /I switch can also be used on the string1==string2 form
of IF. These comparisons are generic, in that if both string1 and
string2 are both comprised of all numeric digits, then the strings are
converted to numbers and a numeric comparison is performed.
The CMDEXTVERSION conditional works just like ERRORLEVEL, except it is
comparing against an internal version number associated with the Command
Extensions. The first version is 1. It will be incremented by one when
significant enhancements are added to the Command Extensions.
CMDEXTVERSION conditional is never true when Command Extensions are
disabled.
The DEFINED conditional works just like EXIST except it takes an
environment variable name and returns true if the environment variable
is defined.
%ERRORLEVEL% will expand into a string representation of
the current value of ERRORLEVEL, provided that there is not already
an environment variable with the name ERRORLEVEL, in which case you
will get its value instead. After running a program, the following
illustrates ERRORLEVEL use:
goto answer%ERRORLEVEL%
:answer0
echo Program had return code 0
:answer1
echo Program had return code 1
You can also use numerical comparisons above:
IF %ERRORLEVEL% LEQ 1 goto okay
%CMDCMDLINE% will expand into the original command line passed to
CMD.EXE prior to any processing by CMD.EXE, provided that there is not
already an environment variable with the name CMDCMDLINE, in which case
you will get its value instead.
%CMDEXTVERSION% will expand into a string representation of the
current value of CMDEXTVERSION, provided that there is not already
an environment variable with the name CMDEXTVERSION, in which case you
will get its value instead.
Creates, changes, or deletes the volume label of a disk.
LABEL [drive:][label]
LABEL [/MP] [volume] [label]
drive: Specifies the drive letter of a drive.
label Specifies the label of the volume.
/MP Specifies that the volume should be treated as a
mount point or volume name.
volume Specifies the drive letter (followed by a colon),
mount point, or volume name. If volume name is specified,
the /MP flag is unnecessary.
Creates a directory.
MKDIR [drive:]path
MD [drive:]path
If Command Extensions are enabled MKDIR changes as follows:
MKDIR creates any intermediate directories in the path, if needed.
For example, assume \a does not exist then:
mkdir \a\b\c\d
is the same as:
mkdir \a
chdir \a
mkdir b
chdir b
mkdir c
chdir c
mkdir d
which is what you would have to type if extensions were disabled.
Creates a directory.
MKDIR [drive:]path
MD [drive:]path
If Command Extensions are enabled MKDIR changes as follows:

mkdir \a\b\c\d
is the same as:
mkdir \a
chdir \a
mkdir b
chdir b
mkdir c
chdir c
mkdir d
which is what you would have to type if extensions were disabled.

will be displayed.
/E Enable extended features
/C Clear screen before displaying page
/P Expand FormFeed characters
/S Squeeze multiple blank lines into a single line
/Tn Expand tabs to n spaces (default 8)
Switches can be present in the MORE environment
variable.
+n Start displaying the first file at line n

are separated by blanks.
If extended features are enabled, the following commands
are accepted at the -- More -- prompt:
P n Display next n lines

Moves files and renames files and directories.
To move one or more files:
MOVE [/Y | /-Y] [drive:][path]filename1[,...] destination
To rename a directory:
MOVE [/Y | /-Y] [drive:][path]dirname1 dirname2
[drive:][path]filename1 Specifies the location and name of the file
or files you want to move.
destination Specifies the new location of the file. Destination
can consist of a drive letter and colon, a
directory name, or a combination. If you are moving
only one file, you can also include a filename if
you want to rename the file when you move it.
[drive:][path]dirname1 Specifies the directory you want to rename.
dirname2 Specifies the new name of the directory.
/Y Suppresses prompting to confirm you want to
overwrite an existing destination file.
/-Y Causes prompting to confirm you want to overwrite
an existing destination file.
The switch /Y may be present in the COPYCMD environment variable.
This may be overridden with /-Y on the command line. Default is
to prompt on overwrites unless MOVE command is being executed from
within a batch script.
OPENFILES /parameter [arguments]

Displays, sets, or removes cmd.exe environment variables.
SET [variable=[string]]
variable Specifies the environment-variable name.
string Specifies a series of characters to assign to the variable.
Type SET without parameters to display the current environment variables.
If Command Extensions are enabled SET changes as follows:
SET command invoked with just a variable name, no equal sign or value
will display the value of all variables whose prefix matches the name
given to the SET command. For example:
SET P
would display all variables that begin with the letter 'P'
SET command will set the ERRORLEVEL to 1 if the variable name is not
found in the current environment.
SET command will not allow an equal sign to be part of the name of
a variable.
Two new switches have been added to the SET command:
SET /A expression
SET /P variable=[promptString]
The /A switch specifies that the string to the right of the equal sign
is a numerical expression that is evaluated. The expression evaluator
is pretty simple and supports the following operations, in decreasing
order of precedence:
() - grouping
! ~ - - unary operators
* / % - arithmetic operators
+ - - arithmetic operators
<< >> - logical shift
& - bitwise and
ˆ - bitwise exclusive or
| - bitwise or
= *= /= %= += -= - assignment
&= ˆ= |= <<= >>=
, - expression separator
If you use any of the logical or modulus operators, you will need to
enclose the expression string in quotes. Any non-numeric strings in the
expression are treated as environment variable names whose values are
converted to numbers before using them. If an environment variable name
is specified but is not defined in the current environment, then a value
of zero is used. This allows you to do arithmetic with environment
variable values without having to type all those % signs to get their
values. If SET /A is executed from the command line outside of a
command script, then it displays the final value of the expression. The
assignment operator requires an environment variable name to the left of
the assignment operator. Numeric values are decimal numbers, unless
prefixed by 0x for hexadecimal numbers, and 0 for octal numbers.
So 0x12 is the same as 18 is the same as 022. Please note that the octal
notation can be confusing: 08 and 09 are not valid numbers because 8 and
9 are not valid octal digits.
The /P switch allows you to set the value of a variable to a line of input
entered by the user. Displays the specified promptString before reading
the line of input. The promptString can be empty.
Environment variable substitution has been enhanced as follows:
%PATH:str1=str2%
would expand the PATH environment variable, substituting each occurrence
of "str1" in the expanded result with "str2". "str2" can be the empty
string to effectively delete all occurrences of "str1" from the expanded
output. "str1" can begin with an asterisk, in which case it will match
everything from the beginning of the expanded output to the first
occurrence of the remaining portion of str1.
May also specify substrings for an expansion.
%PATH:~10,5%
would expand the PATH environment variable, and then use only the 5
characters that begin at the 11th (offset 10) character of the expanded
result. If the length is not specified, then it defaults to the
remainder of the variable value. If either number (offset or length) is
negative, then the number used is the length of the environment variable
value added to the offset or length specified.
%PATH:~-10%
would extract the last 10 characters of the PATH variable.
%PATH:~0,-2%
would extract all but the last 2 characters of the PATH variable.
Finally, support for delayed environment variable expansion has been
added. This support is always disabled by default, but may be
enabled/disabled via the /V command line switch to CMD.EXE. See CMD /?
Delayed environment variable expansion is useful for getting around
the limitations of the current expansion which happens when a line
of text is read, not when it is executed. The following example
demonstrates the problem with immediate variable expansion:
set VAR=before
if "%VAR%" == "before" (
set VAR=after
if "%VAR%" == "after" @echo If you see this, it worked
)
would never display the message, since the %VAR% in BOTH IF statements
is substituted when the first IF statement is read, since it logically
includes the body of the IF, which is a compound statement. So the
IF inside the compound statement is really comparing "before" with
"after" which will never be equal. Similarly, the following example
will not work as expected:
set LIST=
for %i in (*) do set LIST=%LIST% %i
echo %LIST%
in that it will NOT build up a list of files in the current directory,
but instead will just set the LIST variable to the last file found.
Again, this is because the %LIST% is expanded just once when the
FOR statement is read, and at that time the LIST variable is empty.
So the actual FOR loop we are executing is:
for %i in (*) do set LIST= %i
which just keeps setting LIST to the last file found.
Delayed environment variable expansion allows you to use a different
character (the exclamation mark) to expand environment variables at
execution time. If delayed variable expansion is enabled, the above
examples could be written as follows to work as intended:
set VAR=before
if "%VAR%" == "before" (
set VAR=after
if "!VAR!" == "after" @echo If you see this, it worked
)
set LIST=
for %i in (*) do set LIST=!LIST! %i
echo %LIST%
If Command Extensions are enabled, then there are several dynamic
environment variables that can be expanded but which don't show up in
the list of variables displayed by SET. These variable values are
computed dynamically each time the value of the variable is expanded.
If the user explicitly defines a variable with one of these names, then
that definition will override the dynamic one described below:
%CD% - expands to the current directory string.
%DATE% - expands to current date using same format as DATE command.
%TIME% - expands to current time using same format as TIME command.
%RANDOM% - expands to a random decimal number between 0 and 32767.
%ERRORLEVEL% - expands to the current ERRORLEVEL value
%CMDEXTVERSION% - expands to the current Command Processor Extensions
version number.
%CMDCMDLINE% - expands to the original command line that invoked the
Command Processor.
%HIGHESTNUMANODENUMBER% - expands to the highest NUMA node number
on this machine.
Begins localization of environment changes in a batch file. Environment
changes made after SETLOCAL has been issued are local to the batch file.
ENDLOCAL must be issued to restore the previous settings. When the end
of a batch script is reached, an implied ENDLOCAL is executed for any
outstanding SETLOCAL commands issued by that batch script.
SETLOCAL
If Command Extensions are enabled SETLOCAL changes as follows:
SETLOCAL batch command now accepts optional arguments:
ENABLEEXTENSIONS / DISABLEEXTENSIONS
enable or disable command processor extensions. These
arguments takes precedence over the CMD /E:ON or /E:OFF
switches. See CMD /? for details.
ENABLEDELAYEDEXPANSION / DISABLEDELAYEDEXPANSION
enable or disable delayed environment variable
expansion. These arguments takes precedence over the CMD
/V:ON or /V:OFF switches. See CMD /? for details.
These modifications last until the matching ENDLOCAL command,
regardless of their setting prior to the SETLOCAL command.
The SETLOCAL command will set the ERRORLEVEL value if given
an argument. It will be zero if one of the two valid arguments
is given and one otherwise. You can use this in batch scripts
to determine if the extensions are available, using the following
technique:
VERIFY OTHER 2>nul
SETLOCAL ENABLEEXTENSIONS
IF ERRORLEVEL 1 echo Unable to enable extensions
This works because on old versions of CMD.EXE, SETLOCAL does NOT
set the ERRORLEVEL value. The VERIFY command with a bad argument
initializes the ERRORLEVEL value to a non-zero value.
Changes the position of replaceable parameters in a batch file.
SHIFT [/n]
If Command Extensions are enabled the SHIFT command supports
the /n switch which tells the command to start shifting at the
nth argument, where n may be between zero and eight. For example:
SHIFT /2
would shift %3 to %2, %4 to %3, etc. and leave %0 and %1 unaffected.

SORT [/R] [/+n] [/M kilobytes] [/L locale] [/REC recordbytes]
[[drive1:][path1]filename1] [/T [drive2:][path2]]
[/O [drive3:][path3]filename3]
/+n Specifies the character number, n, to
begin each comparison. /+3 indicates that
each comparison should begin at the 3rd
character in each line. Lines with fewer
than n characters collate before other lines.
By default comparisons start at the first
character in each line.
/L[OCALE] locale Overrides the system default locale with
the specified one. The ""C"" locale yields
the fastest collating sequence and is
currently the only alternative. The sort
is always case insensitive.
/M[EMORY] kilobytes Specifies amount of main memory to use for
the sort, in kilobytes. The memory size is
always constrained to be a minimum of 160
kilobytes. If the memory size is specified
the exact amount will be used for the sort,
regardless of how much main memory is
available.
The best performance is usually achieved by
not specifying a memory size. By default the
sort will be done with one pass (no temporary
file) if it fits in the default maximum
memory size, otherwise the sort will be done
in two passes (with the partially sorted data
being stored in a temporary file) such that
the amounts of memory used for both the sort
and merge passes are equal. The default
maximum memory size is 90% of available main
memory if both the input and output are
files, and 45% of main memory otherwise.
/REC[ORD_MAXIMUM] characters Specifies the maximum number of characters
in a record (default 4096, maximum 65535).
/R[EVERSE] Reverses the sort order; that is,
sorts Z to A, then 9 to 0.
[drive1:][path1]filename1 Specifies the file to be sorted. If not
specified, the standard input is sorted.
Specifying the input file is faster than
redirecting the same file as standard input.
/T[EMPORARY]
[drive2:][path2] Specifies the path of the directory to hold
the sort's working storage, in case the data
does not fit in main memory. The default is
to use the system temporary directory.
/O[UTPUT]
[drive3:][path3]filename3 Specifies the file where the sorted input is
to be stored. If not specified, the data is
written to the standard output. Specifying
the output file is faster than redirecting
standard output to the same file.
Starts a separate window to run a specified program or command.
START ["title"] [/D path] [/I] [/MIN] [/MAX] [/SEPARATE | /SHARED]
[/LOW | /NORMAL | /HIGH | /REALTIME | /ABOVENORMAL | /BELOWNORMAL]
[/NODE <NUMA node>] [/AFFINITY <hex affinity mask>] [/WAIT] [/B]
[command/program] [parameters]
"title" Title to display in window title bar.
path Starting directory.
B Start application without creating a new window. The
application has ˆC handling ignored. Unless the application
enables ˆC processing, ˆBreak is the only way to interrupt
the application.
I The new environment will be the original environment passed
to the cmd.exe and not the current environment.
MIN Start window minimized.
MAX Start window maximized.
SEPARATE Start 16-bit Windows program in separate memory space.
SHARED Start 16-bit Windows program in shared memory space.
LOW Start application in the IDLE priority class.
NORMAL Start application in the NORMAL priority class.
HIGH Start application in the HIGH priority class.
REALTIME Start application in the REALTIME priority class.
ABOVENORMAL Start application in the ABOVENORMAL priority class.
BELOWNORMAL Start application in the BELOWNORMAL priority class.
NODE Specifies the preferred Non-Uniform Memory Architecture (NUMA)
node as a decimal integer.
AFFINITY Specifies the processor affinity mask as a hexadecimal number.
The process is restricted to running on these processors.
The affinity mask is interpreted differently when /AFFINITY and
/NODE are combined. Specify the affinity mask as if the NUMA
node's processor mask is right shifted to begin at bit zero.
The process is restricted to running on those processors in
common between the specified affinity mask and the NUMA node.
If no processors are in common, the process is restricted to
running on the specified NUMA node.
WAIT Start application and wait for it to terminate.
command/program
If it is an internal cmd command or a batch file then
the command processor is run with the /K switch to cmd.exe.
This means that the window will remain after the command
has been run.
If it is not an internal cmd command or batch file then
it is a program and will run as either a windowed application
or a console application.
parameters These are the parameters passed to the command/program.
NOTE: The SEPARATE and SHARED options are not supported on 64-bit platforms.
Specifying /NODE allows processes to be created in a way that leverages memory
locality on NUMA systems. For example, two processes that communicate with
each other heavily through shared memory can be created to share the same
preferred NUMA node in order to minimize memory latencies. They allocate
memory from the same NUMA node when possible, and they are free to run on
processors outside the specified node.
start /NODE 1 application1.exe
start /NODE 1 application2.exe
These two processes can be further constrained to run on specific processors
within the same NUMA node. In the following example, application1 runs on the
low-order two processors of the node, while application2 runs on the next two
processors of the node. This example assumes the specified node has at least
four logical processors. Note that the node number can be changed to any valid
node number for that computer without having to change the affinity mask.
start /NODE 1 /AFFINITY 0x3 application1.exe
start /NODE 1 /AFFINITY 0xc application2.exe
If Command Extensions are enabled, external command invocation
through the command line or the START command changes as follows:
non-executable files may be invoked through their file association just
by typing the name of the file as a command. (e.g. WORD.DOC would
launch the application associated with the .DOC file extension).
See the ASSOC and FTYPE commands for how to create these
associations from within a command script.
When executing an application that is a 32-bit GUI application, CMD.EXE
does not wait for the application to terminate before returning to
the command prompt. This new behavior does NOT occur if executing
within a command script.
When executing a command line whose first token is the string "CMD "
without an extension or path qualifier, then "CMD" is replaced with
the value of the COMSPEC variable. This prevents picking up CMD.EXE
from the current directory.
When executing a command line whose first token does NOT contain an
extension, then CMD.EXE uses the value of the PATHEXT
environment variable to determine which extensions to look for
and in what order. The default value for the PATHEXT variable
is:
.COM;.EXE;.BAT;.CMD
Notice the syntax is the same as the PATH variable, with
semicolons separating the different elements.
When searching for an executable, if there is no match on any extension,
then looks to see if the name matches a directory name. If it does, the
START command launches the Explorer on that path. If done from the
command line, it is the equivalent to doing a CD /D to that path.
Associates a path with a drive letter.
SUBST [drive1: [drive2:]path]
SUBST drive1: /D
drive1: Specifies a virtual drive to which you want to assign a path.
[drive2:]path Specifies a physical drive and path you want to assign to
a virtual drive.
/D Deletes a substituted (virtual) drive.
Type SUBST with no parameters to display a list of current virtual drives.

If no date is given, copies only those files whose
source time is newer than the destination time.
/EXCLUDE:file1[+file2][+file3]...
Specifies a list of files containing strings. Each string
should be in a separate line in the files. When any of the
strings match any part of the absolute path of the file to be
copied, that file will be excluded from being copied. For
example, specifying a string like \obj\ or .obj will exclude
all files underneath the directory obj or all files with the
.obj extension respectively.
/P Prompts you before creating each destination file.
/S Copies directories and subdirectories except empty ones.
/E Copies directories and subdirectories, including empty ones.
Same as /S /E. May be used to modify /T.
/V Verifies the size of each new file.
/W Prompts you to press a key before copying.
/C Continues copying even if errors occur.
/I If destination does not exist and copying more than one file,
assumes that destination must be a directory.
/Q Does not display file names while copying.
/F Displays full source and destination file names while copying.
/L Displays files that would be copied.
/G Allows the copying of encrypted files to destination that does
not support encryption.
/H Copies hidden and system files also.
/R Overwrites read-only files.
/T Creates directory structure, but does not copy files. Does not
include empty directories or subdirectories. /T /E includes
empty directories and subdirectories.
/U Copies only files that already exist in destination.
/K Copies attributes. Normal Xcopy will reset read-only attributes.
