Ubuntu command to constantly monitor a service?

I was curious if anyone new a command like tail or top to constantly monitor a service as it runs. I'm trying to watch sendmail currently to see who is connecting to it, but would like to have it a little more dynamic than just repeatedly typing ps aux | grep send

is there a good way to constantly keep this running? Thanks guys n' gals


You can use the watch command along with ps -aux to refresh. watch -n 5 "ps -axf |grep send" will run the ps command every 5 seconds (note the quotes).

  • +1 – I have an alternative use for watch, which is the nastiest hackiest continuous integration ever. watch git pull — Dec 06, 2011 at 00:17
