Advanced Shell Scripting Techniques: Automating Complex Tasks with Bash

Shouldn't the first one be `grep -F/--fixed-strings "${partition}"? The second example will break in any case where $partition contains special characters.

Yes, it's an easy fix though:

    df -h | grep -Po "\d+(?=%\s+\Q$partition\E)"

Oh cool, this is the first time I've heard of `grep \Q..\E'

Thanks!

At some point I should probably write an article about the 20k lines of bash and a little python that power my homelab and various automations. Bash isn't perfect but often 99% good enough is fine.
