perl scripting for checking if a process is running

Hi All,

I am new to perl and have been trying to write a short script to check a process.Though i havent reached to the stage where i can match the output.
I am trying to pass a variable x with value /opt/RGw/csbp-base/CSBP_BAT.01.00.05/csbp_BAT.01.00.05.jar

and then pass another variable y to check if the process is running in the system

ps -ef | grep -i "csbp_BAT.01.00.05.jar" | grep -v grep |awk -F" " '{print $11}'
Though this command works from the command line.but if i run and print the same via the script i get all messed up

#!/usr/bin/perl
$x="/opt/RGw/csbp-base/CSBP_BAT.01.00.05/csbp_BAT.01.00.05.jar";
$y=`ps -ef | grep -i "csbp_BAT.01.00.05.jar" | grep -v grep |awk -F" " '{print $11}'`;
print "\n";
print "$x \n";
print " \n";
print "$y";
print "\n";
#echo $y;
#if [$x=$y]#then
# echo "1st step completed"
# echo "let me try somemore"
#else
#echo "try again"
#echo "will need to see how it works"
#fi
#exit


Thanks in advance for clearing my doubts.

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
