I could use a little help with ps and grep. When running a command like:
# ps -ewf | grep sendmail
root 2730 1 0 Jul14 ? 00:00:01 sendmail: accepting connections
smmsp 2739 1 0 Jul14 ? 00:00:00 sendmail: Queue runner@01:00:00 for /var/spool/clientmqueue
root 6500 6362 0 07:51 pts/3 00:00:00 grep sendmail
Is there any way to run this command and get these results, but exclude
the actual grep itself, which is the last line?
A little background, I have a java based application that I've used a
custom start and stop script for. Basically the stop script does:
stop() {
for pid in `ps -efww | grep myapp | grep -v grep | cut -b 10-15`;do
#echo $pid
kill -9 $pid
done
RETVAL=$?
return $RETVAL
}
This has worked for years, but for some reason it has stopped working. I
think it may be because the process is killing itself before it kills
the app?
I assume the correct way to do this is store the pid in a file that you
reference, but I haven't figured out how to do that yet.
Any help is appreciated.
Thanks,
James
Could it be that the script itself is getting caught in your "ps" and is
getting killed (not the grep embedded in the script)? Could it be the
"cut" part of the line (we've always used 'awk '{ print $2 }' ' in our
stop blocks...never tried the cut idea) that's getting messed up somehow?
