Help! Writing script to show process id
Hello, I am writing a perl script that will just display the process id given a process name.
Here is a piece of it....
$pid = `ps -ef -o pid,ppid,comm | grep xview | awk '{print $1'}`;
print "pid = $pid\n";
now, when I just run this command via command line-->
ps -ef -o pid,ppid,comm | grep xview | awk '{print $1'}
it prints out only the process id number:
55386
However, when I run it in the script, it prints out:
55386 4593 Â xview
Am I using the wrong quotes or something?
