  • This, like the other commands listed here, displays installed arch packages. Unlike the other ones this also displays the short description so you can see what that package does without having to go to google. It also shows the largest packages on top. You can optionally pipe this through head to display an arbitrary number of the largest packages installed (e.g. ... | head -30 # for the largest 30 packages installed) Show Sample Output


    -1
    pacman -Qi | grep 'Name\|Size\|Description' | cut -d: -f2 | paste - - - | awk -F'\t' '{ print $2, "\t", $1, "\t", $3 }' | sort -rn
