Using uppercase variable names is a naming convention you'll see in most scripts out there. You can chose a different convention :) nothing is stopping you :)
sh stands for shell. bash is a shell. Read @maxwell_dev's post at the beginning of the article.
I've been a professional C, Perl, PHP and Python developer.
I'm an ex-sysadmin from the late 20th century.
These days I do more Javascript and CSS and whatnot, and promote UX and accessibility.
Using uppercase is a convention for variables from the parent environment. Lowercase for variables that are local to our script.
I see people use uppercase all the time, but it's usually just because a lot of scripts don't need local variables and that's how they learnt.
I mean, it doesn't really matter... but I am the cheerleader for Team Lowercase.
