Restart Program when crashed
 

I have a program called HelloWorld, but it crashes a lot,

is there anyway to tell Linux to automatically check if Hello World crashed, and if it is crashed, restart HelloWorld?

Thanks!

P.S. Running Ubuntu

Searching for "restart" in apt turned up a few promising hits.

launchtool
monit
restartd

I haven't tried any of these myself.

A simple brute-force way is to run it in a loop.
Any time the command terminates, for any reason, the loop will start it up again. The only way to get out of it is to crtl-c terminate the loop.
