Otherwise, I think the following is what you are looking for:

#!/usr/bin/env perl

use warnings;
use strict;

my $com1;

# replace call to ps with your ps output for this example:
$com1 = <<EOF;
weblogic start
weblogic /export/home/weblogic/bai/bpps.sh
EOF

print "1st\n";
check_for_bpps($com1);

# now assume that ps show that bpps is NOT running:
$com1 = 'foo bar';
print "2nd\n";
check_for_bpps($com1);
exit;

sub check_for_bpps {
    my $com1 = shift;
    if ($com1 =~ /weblogic/) {
        print "bpps is running.\n";
    }
    else {
        print "running com2.\n";
        #$com2 = `sh -c /export/home/weblogic/bai/bpps.sh start 2 > /d
+ev/null 2>&1`;
    }
}

When I run this, I get the following output:

1st
bpps is running.
2nd
running com2.

The key here is that I'm using a regular expression to search for the 'weblogic' string in your ps output.

This variable below is my start up script:

$com2 = `sh -c /export/home/weblogic/bai/bpps.sh start 2 > /d
+ev/null 2>&1`

I want to know how can i run this with root access. What format should it be in? The shell restart script is only going to be used for now i am going to convert it to perl integrate it into the script, but once i starting learning how to walk on my own. I do get the flow of the script. Thanks in advance.
