Bash_unit – bash unit testing framework

You're right, but it's neither of those for command interpolation. Double quotes enable variable expansion, single quotes do not. Command interpolation is back quotes, which is a carryover from sh. The more modern bash way is as follows:

   $ echo $(pwd)

Incidentally: how does one type back quotes on an iPhone?!

Edited to add: shellcheck [0] will flag the back quote usage if you're writing a bash script instead of a sh script.

Longpress single-quote.

That ... lacks discoverability.

`Thank you`!

Like most iPhone tips. How was I to discover long press space bar for cursor placement?! I like it, but discoverability...

It was much better on the 3D Touch equipped models, press “through” the keyboard to get cursor placement, press “through” again while on a word to select the whole word.

ShellCheck always points out backticks as "legacy".
