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