Hi,
I'm trying to find a way to obtain the PID of qmail-send running on a
FreeBSD 4.7 server using the ps and grep functions.

#ps -aux | grep qmail-send
Results in: (some info removed to fit on single line)
root      85  0.0  0.2   872  300 con- I  1:00.62 supervise qmail-send
qmails  6734  0.0  0.3   972  508  ??  S 1:02.04 qmail-send

How do I modify the above command line to have the output be 6734
only?  Note: I only want the PID of the "qmail-send" process (running
as qmails) and not the "supervise qmail-send" (running as root).

TIA,
Shane

use pgrep.  

_line=$(ps -aux | grep qmail-send | grep -v root)
set -- $_line
_pid=$2
echo $_pid

FreeBSD 4.7 doesn't have pgrep as that would have been too easy.
Thanks for your script which works but is there a way to have it all
in one line.  I need to use it in another script which currently is
using:
my ($pidcmd) = 'pidof qmail-send';

TIA,
Shane

Why do you need it all on one line? All that does is make it harder
to read and to update.

That's not a shell script.

ps -aux  | awk '/[q]mail-send/&&$1="qmails"{print $2}'

Use what does the job.

Good luck

If qmails doesn't run any other process, this might do:

ps -u qmails -o pid=

Otherwise:

ps -u qmails -o pid= -o comm= | awk '$2 ~ /qmail-send/ {print $1}'

This should work:

ps -aux | grep qmail-send | grep -v supervise
or
ps -aux | grep qmail-send | grep -v root

Of all the replies this one is the closest to what I'm looking for.
The output of your script results in:

server# ps -aux  | awk '/[q]mail-send/&&$1="qmails"{print $2}'
85
6734

I need just the "6734" being returned as that is the PID of the actual
qmail-send process.    If you can update your script to do this that
would be appreciated.

TIA,
Shane

Wow.  Apparently you have misunderstood the purpose of this group.  It's
not "free consulting for people who want us to do their work for them".
He gave you everything you need, and answering your question doesn't
mean he owes you anything more; your response seems to indicate it does.

Yes, I guess I did misunderstand.  I tought newsgroups could be used
for asking for assistance from people who know more about a subject
then themselves.  Then the more knowledgable people could feel good
about helping someone out.  I know I would return such assistance if I
could and feel great about helping someone.
You're correct about Dave not owing me anything but if he's like me he
wouldn't mind spending another 20s to answer my question exactly as I
had previously stated.
I tought I had done well in posting my question stating exactly what I
was needing and when I didn't get a suitable answer I didn't know I
couldn't ask for additional assistance.
