[stijn_pol]

nuclear_eclipse,
why don't you install Ubuntu server?

where does the output of the command in the first post (to backup) get put?

The directory that you are in. To find this out type (present working directory)

~$ pwd

To put this into a dir called "install" within your home dir you could have

~$ dpkg --get-selections > ~/install/installed-software

function usage()

        echo "USAGE:"
        echo "$0 [-s] [-r] [-f installedpackages.txt]"
        echo ""
        echo "-s ... save installed packages"
        echo "-r ... restore installed packages"
        echo ""
        echo "-f file.txt ... file where installed packages are saved"
        echo "                or from which installed packages are taken"
        echo ""
        exit 0;

while getopts ":srf:" options

   case "$options" in
   s) vsave=1 ;;
   r) vrestore=1 ;;
   f) file="$OPTARG" ;;

   esac
done

function doSave()
{
   dpkg --get-selections > $file
}

function doRestore()
{
   dpkg --set-selections < $file
}

if [ "$vsave" == "1" ] && [ "$vrestore" == "1" ] || [ "$file" == "" ]
then
   usage
fi

if [ "$vsave" == "1" ] && [ "$file" != "" ]
then
   doSave
fi

if [ "$vrestore" == "1" ] && [ "$file" != "" ]
then
   doRestore
fi

The script didn't work for me (posted above) .... just opened up Archive Manager and that's it.

Is there an easy way to tell Ubuntu / dpkg to uninstall every package *except* what's listed in that output file? I'm trying to take an existing install, and remove all the unnecesary packages beyond a basic command line system, but I know of no easy way to do so.

But if I could use a package list from a different system, which is just a command line install, as a basis, and tell it to remove everything but that package list, that would be great.

Have a look here. It might help you.

Could someone post a CLEAN Gutsy Install list??

This might be helpful if you want to uninstall everything except what's listed in your output file: http://www.inportb.com/wp/index.php/...ackages-later/
