shell script to backup installed packages

A quick way of backing up a list of programs is to run this:

dpkg --get-selections > ~/Package.list sudo cp -R /etc/apt/sources.list* ~/ sudo apt-key exportall > ~/Repo.keys It will back them up in a format that dpkg can read* for after your reinstall, like this:

sudo apt-key add ~/Repo.keys sudo cp -R ~/sources.list* /etc/apt/ sudo apt-get update sudo apt-get install dselect sudo dselect update sudo dpkg --set-selections < ~/Package.list sudo apt-get dselect-upgrade -y

• You may have to update dpkg's list of available packages or it will just ignore your selections (see this debian bug for more info). You should do this before sudo dpkg --set-selections < ~/Package.list, like this:

apt-cache dumpavail > ~/temp_avail sudo dpkg --merge-avail ~/temp_avail rm ~/temp_avail Settings and Personal Data

Before you reinstall, you should probably back up the settings from some of your programs, this can easily be done by grabbing folders from /etc and all the content from your user directory (not just the stuff you can see in nautilus!):

rsync --progress /home/whoami /path/to/user/profile/backup/here After you reinstall, you can restore it with:

rsync --progress /path/to/user/profile/backup/here /home/whoami So all together as a pseudo-bash script.

This assumes there is only one user on the machine (remove /'whoami' otherwise) and that you used the same username on both installs (modify dest. of rsync otherwise).

dpkg --get-selections > ~/Package.list sudo cp -R /etc/apt/sources.list* ~/ sudo apt-key exportall > ~/Repo.keys rsync --progress /home/whoami /path/to/user/profile/backup/here

Reinstall now

rsync --progress /path/to/user/profile/backup/here /home/whoami sudo apt-key add ~/Repo.keys sudo cp -R ~/sources.list* /etc/apt/ sudo apt-get update sudo apt-get install dselect sudo dpkg --set-selections < ~/Package.list sudo dselect
