GREP is a filter that searches input files, or the standard input, for lines that contain matches for one or more patterns called regular expressions and displays those matching lines.

This document is the complete revision history, starting with the most recent changes. To use GREP, please see the user guide.

Release 5.33, 19 Aug 2001

This is a repackaging for Simtel; there are no significant functional changes.

Release 5.32, 20 May 2001

If you specified current directory on another disk, such as "d:*.htm", GREP was taking that as root directory, "d:\*.htm". Apparently no one but the program author ever does such a thing!

Release 5.31, 18 April 2001

Unfortunately, a bug was introduced in release 5.3: under certain circumstances, GREP got confused about whether it was working from standard input or input files. This release corrects that bug, with my apologies to everyone who downloaded the buggy 5.3.
