Actually, seems it pads the PID to five digits, so you may or may not get one or more spaces, depending on the width of the PID. Is this version dependent? That would explain why people are trying different things and not getting it right. But IIRC it has been this way in my version of ps for quite some time. Also, if you happen to get PID 123, then the grep will match 1234, 12345 as well, so you should bound it on both sides. Personally, on a Debian-based system, I would perhaps try to use a more specific option to ps(1) to look for the PID in question. "ps --pid $PID" would appear to do that, and seems to return useful error status. You'll also need to redirect to /dev/null if you don't want artefacts to be displayed on the screen (grep -q handled that in the original code).
