All I want is a fucking grep for windows.

http://sourceforge.net/projects/unxutils

1. Download (UnxUtils.zip)
2. Open in in zip/rar/7z/windows explorer, go to the \usr\local\wbin\ folder
3. unzip the grep.exe (into %WINDIR% or into the folder of your choice and and add that folder to the PATH).

Works ouf of the box (well, out of the zip file is a more correct term :)
Have all the options as on unix (--help for example ;-).
Plus you have wget, whoami, zip, unzip, uname, sed, printf, less, wc and all the usual stuff.

FUCK cygwin.
FUCK crappy projects trying to recreate grep.
FUCK those who did not added it to windows by default.
