I could use a little help with ps and grep. When running a command
# 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
root 6500 6362 0 07:51 pts/3 00:00:00 grep sendmail
# ps -ef | grep [s]endmail
instead. Should do what you want (does for me anyway).
Is there any way to run this command and get these results, but
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:
for pid in `ps -efww | grep myapp | grep -v grep | cut -b 10-15`;do
kill -9 $pid
Well, in a shell, $$ is the PID. If you can capture your process PID
when it starts, you simply write it in a file in /var/run/ and when
you stop, you issue a "kill -9 $(</var/run/pidfile)".
This has worked for years, but for some reason it has stopped
think it may be because the process is killing itself before it kills
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.
You can have a look at various init scripts in /etc/init.d/ to get an
idea about how they done it.
