TIL - Ternary in Bash

I have been working with shell scripts for 4-5 years now, and I only recently saw, for the first time, someone shortcut the classic if/else/then statements:

[ $condition == "true" ] && echo "true" || echo "false"

It took me a few minutes of staring at it to make sure it works the way I think it works.

Having seen this though, I still feel it’s better to be a bit more verbose:

if [ $condition == "true" ]; then
  echo "true"
  echo "false"

Better readability, easier to understand, and better for the next guy/gal who needs to read your script.
