If you have done a new installation of Ubuntu or Fedora, then yuou know you have to search all kind of blogs to find out what all to install. So, here is a easier way to do that. Just run this script, it will install some applications which are mostly a “MUST” for all the installations. And the list of applications that are installed are :

colorgcc vim-gnome vim-gtk vlc evolution-exchange vlc smplayer mplayer
w32codecs skype wireshark patch openssh-server tkcvs g++ g++-multilib
libaio1 libpq5 libqscintilla2-8 libfam0 libqt3-mt libc6-dev
ubuntu-restricted-addons ubuntu-restricted-extras and
mediubutu repository.

And here is the script::

#!/bin/bash -
