What does a shell script do on a Raspberry Pi?
A shell script is simply a text file containing a series of shell (command line) commands that are executed one by one, as if they were input directly on the command line. They can save time if you need to execute lots of commands at once, or if you want to execute commands automatically, like when the Pi boots up.

Why does my Raspberry Pi auto run programs?
