grep format assistance required

| 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

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.

That's correct. Consider - Give a man a fish and feed him for a day.
Teach a man to fish and feed him for life. Thus a partial answer that
gives a pattern that can be built upon is actually a superior answer
than just typing in a script.

One thing I've learned when teaching UNIX - The folks who write down
exactly what I'm typing come ask again when they least variation is
needed and as such they aren't learning any concepts. The folks
who write down skeleton forms based on what I've typing come back
to show off variations and as such have been learning concepts.
So look at the material. Think about why it works. Build a variation
based on the concepts demonstrated. Post what you ended up using.
Trigger professional pride in self and in teacher by both. And in the
process become a contributor. Take and give bundled together.

Thought you had figured out the problem, which should be obvious
if you print $0 instead of $2.
ps -aux | awk '/[q]mail-send/&&$1="qmails"{print $2}'
Should be:
ps -aux | awk '/[q]mail-send/&&$1=="qmails"{print $2}'

Please omit the "-" in BSD options (and have "-" in SysV options);
I have seen a Linux ps that otherwise sais "depreciated".
aux is BSD:
ps aux | awk '$NF=="qmails-send" {print $2}'
Some systems have pgrep:
pgrep -x qmail-send
