An improvement upon while true loop

The story

So normally when I want to see output for something, I’ll run a while true loop.

while true; do zabbix_get -s -k 'task.converter_cpu'; done

That doesn’t always stop even when I mash ^C (CTRL+C).

The solution

So I offer my improvement. The way to stop the loop is obvious, and also I will explain it.

while test ! -f /tmp/foo; do zabbix_get -s -k 'task.converter_cpu'; done

To stop the loop, in another shell just:

touch /tmp/foo
