notify if a process take more than X time

[Pol Hallen <deben@fuckaround.org>]

Hi all,

I need add to my script a notify if a process take more than X time, so 
using ps I can see what time take a process:

ps -ao cmd,etime|grep backup
/bin/sh ./backup    03:44:55

what's the easy way to do a notify by email?

redirect output of ps to file and use sed for analize the past time, 
next verify with if/then or there's a better way?

any idea?

thanks for help!
