Dear grep programmers, I found an interesting case of grep malfunctioning and I'm not sure if it's Cygwin's fault or greps... in either case it has stumped even the nerdiest of my colleagues as well as I.
Simple examples show a Cygwin machine vs. an Ubuntu machine. Sorry about the ugly ascii text documenting this... wasn't sure if you guys accept HTML formatted e-mails. ====================== 1. Cygwin Windows XP: ====================== $ grep --version grep (GNU grep) 2.5.1 Copyright 1988, 1992-1999, 2000, 2001 Free Software Foundation, Inc.

[EMAIL PROTECTED] /c/music/nsf $ echo x.nsF | grep -i '[^ ]\+\.nsf$' x.nsF ^^^^^^^^^^^^^^ =====> omitting -o option makes the regex match now.... but I still need -o on this one.
