Happy Almost New Year!
I want to run a command inside a script. From the shell, here's the command:
% ps -ef | /bin/egrep '/usr/lib/sendmail' | /bin/grep -v grep | /bin/awk '{print $2}' 19460
What is returned is the pid of the process being grep'd.
But, when I put this into a test script,
my $pid = `ps -ef | /bin/egrep '/usr/lib/sendmail' | /bin/grep -v grep | /bin/awk '{print $2}'`; print "\$pid is: $pid \n";
here's what I'm seeing ,
$pid is: root 19460 1 0 Dec 18 ? 0:08 /usr/lib/sendmail -bd -q15m

It seems to be only going as far as dropping off the grep, and not doing the
awk '{print $2}'. I've tried this with the system() call, with the same
results.
Try changing the $2 to \$2. Perl is interpolating $2 before it gets to bash, so bash sees "/bin/awk '{print }'".
