FULL DISCUSSION
 

by convention, variable names should be all in uppercase.

A lot of scripts do that, so you could call it a convention, but generally you should only use ALL_CAPS_NAMES for environment variables or other stuff that's part of the shell's world. Variables local to scripts should be lower_snake_case to avoid collisions and hint that they're not going to have any effects outside the script.
