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

Sorry guys, I just realized I'm posting on serverfault not superuser, huge apologies for "wrong forum"

tail -f /var/log/mail.log | fgrep send – mailq Dec 5 '11 at 23:22
Awesome I didn't think about just tailing the file. Thanks mailq – ehime Dec 5 '11 at 23:24

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).

Great this is the answer, just waiting for the four minutes to chalk down to accept. Thanks slillibri (sp?) – ehime Dec 5 '11 at 23:25
I have an alternative use for watch, which is the nastiest hackiest continuous integration ever. watch git pull – Tom O'Connor Dec 6 '11 at 0:17
