vlad doster eed099b954 Cohesive shell script formatting
- Format all shell scripts using [shfmt]
  (https://github.com/mvdan/sh).

Options used:

* `-bn`: binary ops like && and | may start a line
* `-sr`: redirect operators will be followed by a space
* `-ci`: indent switch cases
* `-i 4`: indent 4 spaces
* `-s`: simplify the code
* `-p`: parse for posix compliance

- Add Github action to lint changes to scripts and enforce formatting
  going forward
