Re: chomp operator

Hi Kaushal,

Yes you are right if you have a hardcoded line of text in your script you
know if there is a "\n" or not at the end.

Now imagine you are reading a bunch of data from a text file created from
user input or some unknown script... who knows how much weird things are
there at the end of those lines.
So in order to save you a huge headache perl offers you the chomp operator
to at least get rid of the line feeds.

Regards,

Rob

Hi,

I have the below lines of code.

#!/usr/bin/perl
use strict;
use warnings;

my $text =" a line of text\n" ;
chomp($text); #the chomp operator gets rid of the newline character
print "$text";

My question is if i remove the new line character "\n" in the above code
then i dont need the chomp operator if my understanding is correct.

so where does the chomp operator plays its role, can some one explain me
here with a sample of code.

Thanks and Regards
