You’re mostly proving the parent’s point here. Yours isn’t a one liner, and even in Bash people don’t write multi-line for loops in one line. I don’t know what you mean about the first two lines being overhead; this doesn’t work without them, and you have magical options “shell” and “text” in there that matter. Your script doesn’t pass the result to another process, so you need another line. This also splits output on spaces, it should be more generic. Doing that involves another module (regex), another function call (or more likely several), and several more lines.
Compared to “last -a | grep tmux | process”, your script is much closer on a log scale to 30 lines than 1, even if the parent’s 30 is a little exaggerated, and even if we use the 5 lines you showed and not the ~10-12 lines it really would be.
