Listing of space used by programs

  • 772

I would like to get a listing of the space used by programs, preferably with the largest listed first.

I am keeping 18.04 ONLY since 20.04 has "broken" my Canon TS9120 scanner.

I could then un-install those programs that are not needed.

    Method #1

    This one is relatively straightforward. You're going to open your terminal, do a search, and then sort that information.

    Press CTRL + ALT + T and open the terminal. Enter the following and press the enter button.

    dpkg-query -W -f='${Installed-Size;8}  ${Package}\n' | sort -nr

    That's going to flood your window, so you can easily send it to a text file.

    dpkg-query -W -f='${Installed-Size;8}  ${Package}\n' | sort -nr >> appsizes.txt

    That will make a text file in your home directory with the name of appsizes.txt and you can use that as reference.

    Method #2

    Open your favorite plain text editor and cut/paste the following:

    #!/bin/bash

export LC_ALL=C

aptitude show $(dpkg-query -Wf '${Package}\n') |
  awk '$1 == "Package:"     { name = $2 }
       $1 == "Uncompressed" { printf("%10s %s\n", $3, name) }' |
  awk '$1 ~ /k/ { $1 *= 1 }; $1 ~ /M/ { $1 *= 1024 }
       { printf("%9d %s\n", $1, $2)}'

    Now, save it (preferably in your home directory) as applist.sh.

    Open your terminal and enter the following:

    chmod +x ./applist.sh
./applist.sh

    That'll do pretty much the same as the first method - except you can just execute the script whenever you want. If you want to be all fancy, try this (make sure you've made it executable in the step above:

    sudo cp ./applist.sh /usr/bin

    Now, no matter what directory you're in with your terminal, you can just run applist.sh. If you want to make it a text file, you can still do something like applist.sh >> ~/applist.txt.
