Tool to run a command until exit status is 0

Question

Is there a tool that can accept a command and run it over and over until exit status is 0?

I could probably check for value of $? in a loop but I wonder if there's a standard program for this

No, I think the loop is so trivial it hasn't been encoded into a command. Something like

while !cmd; do sleep 1; done

Or `until cmd; do :; done` to use `until` and without the delay. – Kusalananda Dec 18 '18 at 07:01
