apt is a very cool and easy to use package manager for UNIX based systems. Here are some simple and effective commands that might help you do things XD
apt-get update – makes sure that all the information is newest.
apt-get upgrade – checks for all packages that needs to be updated.
apt-get remove <package> – Removes the package from the system.
apt-get purge <package> – Same as remove but deletes all the configuration files.
apt-cache search – This can be useful if you don’t know the package name, e.g “apt-cache search “stats” | more”
apt-cache depends <package> – Lists all the packages dependences.
apt-get -u install <package> – Updates just the specified package.
