Killing child process in ksh
I have a script that (ideally) starts tcpdump, sleeps a given number of seconds, then kills it.
When I do this for 10 seconds or and hour, it works fine. When I try it for 10 hours (the length I actually want) it just doesn't die, and will actually stick around for days. Relevant part of my script: secondstime=$(($HOURSRUN * 60 * 60)) tcpdump -ni hme0 -w ${LOGDIRECTORY}${LOGFILE}`date +%m%d`.log -F $EXPRESSIONFILE& sleep $secondstime kill %1 Using 'ps', I can see that sleep got the right number of seconds. My ksh version is: @(#)PD KSH v5.2.14 99/07/13.2 Any ideas or better ways to do this would be appreciated. |
