  109. ECHO Use Regular eXpressions in the DIR command.
  110. ECHO.
  111. ECHO Usage:   RXDIR  ^<file_spec^>
  112. ECHO.
  113. ECHO Where:   ^<file_spec^>  is a regular expression specifying the files to display
  114. ECHO.

  116. ECHO.
  117. ECHO Notes:   1. This batch file uses EGREP to interpret the regular expression.
  118. ECHO             EGREP is available in many varieties on many sites.
  119. ECHO             This batch file has been tested with GNU grep 2.4.2, available
  120. ECHO             at http://unxutils.sourceforge.net/
  121. ECHO          2. File specifications are case insensitive.
  122. ECHO          3. All matching files will be displayed, including hidden files.
  123. ECHO          4. This batch file searches the current directory only.
  124. ECHO          5. The regular expression also matches the date, time and size parts
  125. ECHO             of DIR's output; examine the source to understand the limitations.
  126. ECHO.
