Is there any command that prints only the name of the packages that apt-get autoremove selects? I'm creating a script that updates the kernel, removes the old kernel and the unnecessary packages (apt-get autoremove), but I want to print on the screen the list of packages that will be removed by apt-get autoremove, how can I do this?

  • You should just be able to get it to run sudo apt-get autoremove -y and it should autoremove anything needed to be removed...

  • To get the list of packages without removing them actually you can do sudo apt-get --dry-run autoremove

  • I just want to get the name of the packages, not the entire output of the command.... Jul 24 '15 at 20:53

Since as per your comment you want to list only the packages that are going to be removed:

apt-get --dry-run autoremove | grep -Po '^Remv \K[^ ]+'

grep command breakdown:

  • -P: Interprets the given pattern as a PCRE (Perl Compatible Regular Expression) pattern
  • -o: Prints only the matched string instead of the whole line

Regex breakdown:

  • ^: matches the start of the line
  • Remv: matches a Remv string
  • \K: excludes the previously matched substring from the matched string
  • [^ ]+: matches one or more characters not
$ apt-get --dry-run autoremove | grep -Po 'Remv \K[^ ]+'
  • 1
    @GeekLynxAfonso, you don't need to use sudowith --dry-run option.

  • @jarno Makes sense, the fact that it was probably not needed didn't occur to me. Thanks

Actually you only need to filter the output of your

sudo apt-get autoremove --dry-run 


For instance you can do it with

sudo apt-get autoremove --dry-run  | head -n 5 | tail -n 1
  • Your command works too!! But I prefer the kos's command... But thanks in same!! :) Jul 25 '15 at 14:23
