I'm trying to figure out a process that monitors users sessions on a remote server and alerts them when they are being idle too long, which with the Linux command
w is aptly appropriate.
Problem is -
w uses 3 different formats to specify the idle time of the session, and I can't figure them out properly. An output of
w might look like this:
11:40:57 up 400 days, 10:46, 13 users, load average: 5.07, 5.10, 4.83 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT john pts/1 XX.XX.XX.XX Wed13 22:29m 0.13s 0.04s ssh master-db june pts/2 XX.XX.XX.XX Wed13 46.00s 0.67s 0.13s -bash jenn pts/4 XX.XX.XX.XX 11:13 27:47 4.16s 0.11s -bash
As you can see, IDLE has different formats for each of the users:
- "AA.BBs" obviously means that AA seconds and BB 1/100ths of a second (46 seconds in the case of June) has passed since she was last active on the console.
- "AA:BBm" probably means that AA hours and BB minutes have passed since John was last active on his session.
- "AA:BB" is the format I can't figure out - how long has Jennifer not being active in her session?
