Ok thanks Sam here is why I asked the question:
This is what you get:
# Medibuntu repository (Multimedia, Entertainment & Distractions In
Ubuntu) is a repository of packages that cannot be included into the
Ubuntu distribution for legal reasons (copyright, license, patent, etc).
# win32 codecs (divx, xvid etc) and DVD support globally
# Firefox support for Flash, Java, MPEG, DVD, DivX support
# Google Earth
# RAR compressor/decompressor
# Compiz Config Settings Manager
# Ubuntu Tweak
# media player similar to KDE’s Amarok but for Gnome
# MPlayer and VLC video players
# SSH Server to allow you to connect remotely to your computer
# The ability to listen and rip Internet radio stations
# More codecs
Get the script:
|$ wget http://www.linuxlove.org/stuff/postinstall.sh|
Edit and add/remove things you need/don’t need (add a ‘#’ in front of
the line installing what you don’t want):
|$ nano -w postinstall.sh|
Run the script:
|$ chmod +x postinstall.sh
|So I DLed the script from the url above and in looking at it i realized
I was sure about some things but not all to '#' out. I'm new and do not
always understand when looking at commands how the hell Linux knows what
to do from the command, so makes me nervous.
Thanks for the info.
