re: Bash from scratch: learn enough bash to write your own scripts VIEW POST

re: Thanks Ahmed for this concsice article covers shell scripting essentials which will help in writingand understanding the bash doubt is 1....

Hey, Glad you liked it!

  1. 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 :)
  2. sh stands for shell. bash is a shell. Read @maxwell_dev's post at the beginning of the article.

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.
