One place where chomp() comes in handy is when you're reading from a
file.
Usually a line read from a file will have a newline at the end.
The terminating new line may get in the way of your processing, here's a
contrived example:
my $foo = 'some text to append to line\n';
open my $TESTFILE, '<', '/some/test/file') or die;
while ( defined (my $line = <TESTFILE>) ) {
# $line contains 'Some arbitrary text \n'
print $line, $foo;
}
Without a 'chomp $line' the program will print:
Some arbitrary text
some text to append to line
Instead of:
Some arbitrary text some text to append to line
as was probably intended.
