Variables in Bash Script
ShellCheck warns about this and other common problems
-
Can't figure out how to accept user input to break out of while loop
This, plus [shellcheck](https://www.shellcheck.net/) or something similar should help you figure out most problems a LOT faster.
-
I can't for the life of me figure out the weird syntax!
shellcheck is quite nice to check your syntax for mistakes, even ones that don't usually cause issues but perhaps on files with spaces in their names, etc.

i was watching a tutorial of learning bash but came across this error. can anyone help?
Final suggestion, run your script through https://www.shellcheck.net/ to get suggestions on improvements.
-
Choosing an improved terminal/shell and need help
A tool like shellcheck can help quite a bit in navigating bash requirements: https://github.com/koalaman/shellcheck I'd suggest using Zsh interactively (w/ syntax highlighting, autocompletion, easy to use hook functions, etc.); & stick to bash with shellcheck analysis for scripting generally.

AWK return/print as nested array in Bash
So you probably want two nested while loops as you count down or up the array. These examples should fix you up. I recommend the vanilla POSIX while example, and install the command-line version of shellcheck to lint your code as you go along.

Why does this command always output "bar"
Note, also: https://github.com/koalaman/shellcheck/wiki/SC2015
- My code isn’t working as expected, would like some help
-
Bash script to generate patched APK
shellcheck should have caught the above, so the best tip of this lot is probably to introduce you to shellcheck if you weren’t aware of it. It’s not always right, but it’s caught a lot of bugs that I would have otherwise committed.

Code formatter, linters, etc. Recommendations?
There is shellcheck, and shellharden which is a strict version of it. There are similar stuff here, some that also help with your editor. You can also use a docker version of shfmt. See here for a quick tutorial on shfmt.
