I knew that I tried to keep the script very simple not using too much of perl expressions so that beginners can understand what's happening with the script. Anyways, I modified the script to user regular expressions and is pasted below thanks for making me write this
Code:
#! perl
$passwdfile = "passwd";
die "Input a pattern as argument!" if (not $ARGV[0]);
@loggedOn = `who`;
foreach $name (@loggedOn) { $n = (split(/\s+/,$name))[0]; next if $n !~ /^$ARGV[0]/i; $users{$n} = 1; }
die "Pattern doesn't match into any of the logged on users" if (not scalar keys %users);
open (file, $passwdfile) || die "couldn't open $passwdfile: $?";
foreach $line (<file>) {
($username,$fullname) = (split(/:/,$line))[0,4];
$fullname =~ s/,/ /g;
$full{$username} = $fullname;
}
foreach $i (sort keys %users) {
if (not exists $full{$i}) {print "WARNING: $i is not in passwd file\n"; next;}
print "Hello ***$full{$i}\n";
}

dshbak
DSHBAK(1) General Commands Manual DSHBAK(1)NAME
dshbak - format output from pdsh command
SYNOPSIS
dshbak [OPTION]..
DESCRIPTION
The dshbak program formats pdsh pdsh output for humans. Output from each node is consolidated, the leading "node:" is stripped, and a
header block with the node name is added. If the -c option is specified, nodes with identical output are not displayed twice; instead, the
header will contain a list of nodes. The list of nodes is further compressed into node ranges if the node names have a numeric suffix.
OPTIONS -h Display a summary of command line options.
-c Do not display identical output from nodes twice. Instead, print the list of nodes with matching output in the header block.
-d DIR Write consolidated node output to separate files in output directory DIR. Any existing files will be overwritten.
-f With -d, force creation of specified DIR.
ORIGIN
A rewrite of IBM dshbak(1) by Jim Garlick
<garlick@llnl.gov> on LLNL's ASCI Blue-Pacific IBM SP system.
