awk command with PERL

Hi All,

My Input file looks like below:

Input:
100,200,300

$fw=`head -1 test.csv | awk -F, '{print \$1}'`;
$fw="'$fw"
$fw="$fw'"
print $fw

Output:'100'

I want the first field to be printed in single quotes ('') like above.
I could get the ouptput but the problem is single quote (') is printed in next line below.
'100
'
I dont know how to avoid this space.

NAME
IO::Digest - Calculate digests while reading or writing SYNOPSIS
use IO::Digest; # Get a Digest::MD5 object that takes input while $fh being written or read $iod = IO::Digest->new ($fh, 'MD5'); print $fh "fooo"; print $iod->hexdigest DESCRIPTION
This module allows you to calculate digests while reading or writing file handles. This avoids the case you need to reread the same content to compute the digests after written a file. TEST COVERAGE
