Finally, I would like to thank Andrew Hume for many fascinating discussions
Mike Haertel would like to thank Andrew Hume for many fascinating discussions
of string searching issues over the years. Hume & Sunday's excellent
paper on fast string searching (AT&T Bell Laboratories CSTR #156)
describes some of the history of the subject, as well as providing
exhaustive performance analysis of various implementation alternatives.
The inner loop of GNU grep is similar to Hume & Sunday's recommended
"Tuned Boyer Moore" inner loop.
More work was done on regex.[ch] by Ulrich Drepper and Arnold
Robbins. Regex is now part of GNU C library, see this package
for complete details and credits.
Arnold Robbins contributed to improve dfa.[ch]. In fact
it came straight from gawk-3.0.3 with small editing and fixes.
Many folks contributed see THANKS, if I omited someone please
send me email.
Alain Magloire is the current maintainer.

Version 2.3:
- When searching a binary file FOO, grep now just reports
`Binary file FOO matches' instead of outputting binary data.
This is typically more useful than the old behavior,
and it is also more consistent with other utilities like `diff'.
A file is considered to be binary if it contains a NUL (i.e. zero) byte.
The new -a or --text option causes `grep' to assume that all
input is text. (This option has the same meaning as with `diff'.)
Use it if you want binary data in your output.
- `grep' now searches directories just like ordinary files; it no longer
silently skips directories. This is the traditional behavior of
Unix text utilities (in particular, of traditional `grep').
Hence `grep PATTERN DIRECTORY' should report
`grep: DIRECTORY: Is a directory' on hosts where the operating system
does not permit programs to read directories directly, and
`grep: DIRECTORY: Binary file matches' (or nothing) otherwise.
The new -d ACTION or --directories=ACTION option affects directory handling.
`-d skip' causes `grep' to silently skip directories, as in grep 2.2;
`-d read' (the default) causes `grep' to read directories if possible,
as in earlier versions of grep.
- The MS-DOS and Microsoft Windows ports now behave identically to the
GNU and Unix ports with respect to binary files and directories.
Version 2.2:
Bug fix release.
- Status error number fix.
- Skipping directories removed.
- Many typos fix.
- -f /dev/null fix(not to consider as an empty pattern).
- Checks for wctype/wchar.
- -E was using the wrong matcher fix.
- bug in regex char class fix
- Fixes for DJGPP
Version 2.1:
This is a bug fix release(see Changelog) i.e. no new features.
- More compliance to GNU standard.
- Long options.
- Internationalisation.
- Use automake/autoconf.
- Directory hierarchy change.
- Sigvec with -e on Linux corrected.
- Sigvec with -f on Linux corrected.
- Sigvec with the mmap() corrected.
- Bug in kwset corrected.
- -q, -L and -l stop on first match.
- New and improve regex.[ch] from Ulrich Drepper.
- New and improve dfa.[ch] from Arnold Robbins.
- Prototypes for over zealous C compiler.
- Not scanning a file, if it's a directory
(cause problems on Sun).
- Ported to MS-DOS/MS-Windows with DJGPP tools.
See Changelog for the full story and proper credits.
Version 2.0:
The most important user visible change is that egrep and fgrep have
