alt Hacker NewsWhy take a perfectly readable if-statement and turn it into something, 99.9% of people would need to lookup. Concise != better. You can make it one line with:
[ -z "$1" ] && { echo "missing argument, aborting." 1>&2; exit 1 }Replies

I believe you missed a semicolon after `exit 1` and before `}`. `}` closes the opening `{` only at the start of a command (POSIX rules; don't remember now if bash recognizes it when it's just a command argument).

the people writing it are doing it for themselves probably. i wouldn’t expect it to survive a code review. the necessity of using esoteric bash features or syntax is a pretty good smell that you should be using something else imo.
different strokes of course.
