Cygwin ToolsOriginally Posted by dodgyedgy
It's a full GNU environment compiled for windows.
So, basically, you get a bourne shell, + all the usual UNIX / Linux commands (grep, ls, ps etc. - as well as the powerful UNIX-style regular expressions), and all the benefits of shell scripting, without actually running Linux.
You can run most Linux software on it too, so long as you don't mind compiling it.
