Not stopping program (using shell script)

Question

I have a binary program named as some thing like "mm.out". This program has some unexpected bugs and the bugs causes it to stop. I want to write a service or shell script to execute my binary again if it stopped unexpectedly. How should I write this program?

You should debug your program (use a debugger like `gdb`, and set the core dump file limit to a suitable value). You might write a `while` loop inside a shell script. — Basile Starynkevitch, Feb 18 '12 at 18:20

You should fix the program. But if you really want this, run it in a loop:

while ! mm.out
do
    sleep 5    # Just in case the program dies immediately
done

maybe what he means is to get it to start running once it stops (Automatically) – Feb 18 '12 at 18:21

@Nunoxic That's exactly what this is doing. – cnicutar Feb 18 '12 at 18:22
Are we to assume that only 1 instance of the code is allowed at a given time? – Feb 18 '12 at 18:30
@Nunoxic Haven't thought of that. I guess so. – cnicutar Feb 18 '12 at 18:31
If it is, your code is impeccable. Else, we would need to interface it with `ps | grep mm` or something? – Feb 18 '12 at 18:34
@Nunoxic I'm actually a beginner, I'm sure it's flawed. I would go with `pgrep`. – cnicutar Feb 18 '12 at 18:35

Let a shell script execute it and wait for a return code, if that code isn't 0 restart the program.
