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

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
