Currently in 2007 you ship grep 2.4.2 in UnxUtils. I read from the website that you already made unxupdates in 2003 with some important feature difference such as grep 2.5.1.
Grep 2.5.1 is different from 2.4.2., e.g. -o, -P are two that I know of.
Any reason why you pulled down the grep 2.5.1?
Will you be reposting grep 2.5.1?
Or should I migrate to GnuWin32's grep 2.5.1a?
Quote from the UnxUtils project website:
updated grep v2.5.1: there was a bug in grep -r pattern .
updated sort.exe: Fixed a bug with sorting larger files
updated grep v2.5.1: the -P option (Perl-style regexes now works)
