Arch Linux sort installed packages by size

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 current folder permission from /, useful for debugging ssh key permission

Handled all within awk. Takes the value from $PWD and constructs directory structures and runs commands against them. The gsub() call is not necessary, but added for better visibility.

If a variable DIR is given on the awk command-line, then that directory is used instead:

awk -vDIR=$HOME/.ssh 'BEGIN{dir=DIR?...}'
