simple-scripts

A collection of simple but useful Bash scripts so I don't have to remember the commands. Most scripts deal with .pdf or video file manipulation/conversion. Some scripts have become less "simple" over time as I add more functionality, but my goal is to make the code easy to understand over making it compact or efficient.
