Line User Interface (LUI) 101

All Linux distrobutions have subtle differences. These commands will generally work cross distro's. consult google. :)

sing dpkg to install packages

dpkg is a command-line tool used to install packages. To install a package with dpkg, open a Terminal and type the following:

cd directory
sudo dpkg -i package_name.deb

Note: replace directory with the directory in which the package is stored and package_name with the filename of the package.

It is recommended that you read the dpkg manual page before using dpkg, as improper use may break the package management database. To view the manual page for dpkg, open a Terminal and type man dpkg.

Getting a list of recently installed packages

You can use the dpkg logs to discover recently installed packages; this is handy if you want to roll back some recent installations to a previous system state.

zcat -f /var/log/dpkg.log* | grep "\ install\ " | sort
