So, is it possible to update and upgrade without running:

sudo aptitude update && sudo aptitude upgrade

Meaning, is there one command that can do both?

Unfortunately, the two commands have to be executed separately.

Thanks! This answers it perfectly! – polandeer Jul 10 '12 at 0:09

If you are annoyed by too much typing, you can define yourself an "alias". This can be done e.g. by adding a line to the end of your $HOME/.profile like this:

alias sau='sudo aptitude update && sudo aptitude upgrade'

(of course you can replace "sau" by something else -- for me that's an acronym to Sudo Apt-get Update). After saving the file, open a new shell (or "source" the .profile again running . $HOME/.profile. Now you can always simply type "sau" to do the complete job. Works great for me with multiple machines.

Hm. I guess I was just asking someone to tell me to alias it :P – polandeer Jul 10 '12 at 0:09
Yeah, but that's the only way to do it with a "single command". And your question did not exclude this ;) – Izzy Jul 10 '12 at 8:13
Tricky. Anyways, the only reason I asked was because I wanted to understand apt better, not because I'm too lazy to write sudo aptitude update && sudo aptitude upgrade The reason I asked was because you can do it with pacman (sudo pacman -Syu --noconfirm). – polandeer Jul 12 '12 at 12:14
If you have to do that often and on multiple machines, you're glad you can at least have an alias. However: apt-get update has a parameter -u, according to the man page that shows available updates. Did not try whether it then asks to apply them (have no Ubuntu/Debian near me to check right now). – Izzy Jul 12 '12 at 13:31
