apt-get doesn't incredibly enough have a man page but $ apt-get --help|grep -E 'clean|autoremove' autoremove - Remove automatically all unused packages clean - Erase downloaded archive files autoclean - Erase old downloaded archive files(if this was a small disk, then also localepurge might come handy, read its caveats though)
