I have just been given the assignment of writting a deamon that would monitor
a list of programs for inactivity and after a certain amount of inactive time,
send a signal to the process. The process would then do a gracefull shutdown.
One requirement is that this program must work under SysV and BSD (SunOS).
Can anyone point me in the right direction?
Thanks in advance.

Just write a shell script loop which uses awk to suck out the TIME field of the procs as reported by ps and see if it's changing or not. The only problem is that the command-line flags are gratuitously different for ps on SYSV and BSD (tho Sun/OS must have the SYSV clone version.) You could probably do some test to just change the flags fields. For a problem like this I'll bet you a nickel crafting the whole thing in C using /dev/kmem etc will not be much faster than the above described script, and will take a week to get right instead of 30 minutes. (hmm, just checked, Sun/OS doesn't seem to have a SYSV clone ps, probably for the same reason people don't serve cooking wine at their dinner table.) -- -Barry Shein Software Tool & Die | bzs@world.std.com | uunet!world!bzs Purveyors to the Trade | Voice: 617-739-0202 | Login: 617-739-WRLD

The process would then do a gracefull shutdown. Just as a followup to this, I found out how to access the process table in SunOS last night via the kvm_* calls and now I need to find equivalent functions under SysV 3.2 (BTW, this SysV I'm working on is on a Unisys U6000). -- Glenn Pitcher UUCP: {crash,ucsd}!edpmgt!gpitcher Programmer/Analyst & hp-sdd!teamnet!gpitcher Unix Guru in training INTERNET: gpitcher@edpmgt.cts.com EDP Management, Inc. * Proud member of Team.Net * =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
