There are many utilities in Linux/Unix which are very useful in our life say for example sed, awk, grep, etc. Some of us might have wished Windows/DOS environment to have similar kind of utilities. Anyway I did. Today I came across some of the open source projects, while googling, which provide some of the utilities in Windows too and thought of sharing :)
The projects are GnuWin and UnxUtils.
GnuWin - http://sourceforge.net/projects/gnuwin32/
UnxUtils - http://sourceforge.net/projects/unxutils/
