Good morning Monks, I'm trying to do the bash equivalent of awk on a grep output of a linux process. The idea is to extract the process ID of an application running on the server. Code looks like this:

#!/usr/bin/perl

@array = `ps -ef | grep kdfadm`;
@A = grep (/\/opt\/kdf\/home/, @array);

my @A = split;
print $A[1];

Code output (shortened for readability):

[kdfadm@srv01 ~]$ /usr/bin/perl SplitTest
kdfadm   121562 121527  0 Nov13 ?        00:01:15 /opt/kdf/home/jdk1.8
+.0_162/jre/bin/java -Xms512m -Xmx512m ...
[kdfadm@srv01 ~]$

I've come to grasp that the output is essentially the first line, as opposed to the first field. How do I perform the equivalent of "awk {'print $1,$2,$8'}" in perl?
