https://community.hpe.com/t5/operating-system-linux/determining-the-elapsed-time-for-a-process-etime/m-p/2820795#M2682 I am trying to write a very simply script taht simply check if a process has been running for more than an hour and then kills it. With the complications of the 24 hour clock I was hoping there was a simply ps option that simply gave me elapsed time. In the man page there does appear to be an option of etime, however I am unable to get this to work has anyone got any ideas.

You might want to do checks for a given process etc. etc., but, that's the basics.<BR /><BR />Hope it helps!<BR /><BR />NOTE: The 'ps' man page gives you lots of options of how you want the output of PS to look. Using the '-o' operator, you supply a comma-separated list of the fields you want. Using the '=' after it means "don't print the title of this field" Wed, 09 Oct 2002 00:21:02 GMT https://community.hpe.com/t5/operating-system-linux/determining-the-elapsed-time-for-a-process-etime/m-p/2820796#M2683 Stuart Browne 2002-10-09T00:21:02Z
