For all you Linux fans out there, that use a lot of linux commands (sed,ls,awk,etc) and would like to have this also on linux, you can give UnxUtils a try. The big differences between UnxUtils and Cygwin is that UnxUtils uses executables that are only dependent to Microsoft C-runtime (msvcrt.dll).
All you have to do is:
1. Download the zip file from owners site
2. Unzip the file in any location (preferably C:\Program Files (x86)\UnxUtils )
3. Add the path C:\Program Files (x86)\UnxUtils\usr\local\wbin to the System Variables PATH (Start – Control Panel – System – Advanced system settings – Advanced – Environment Variables – System variables – PATH – edit)
You can find a complete list of programs that are ported on the UnxUtils site.
