Hi there, I'm new to Perl.
How do I remove the last character of a scalar?
For example, I have
$temp = "1234\n";
I want to get rid of the '\n', is there a function, or a regular operation to do that?
Thanks much.

try this.

$temp=chomp($temp);

OR

$temp=~ s/\n//g;

OR

$temp=chop($temp)

chomp and chop don't need to be assigned to $temp again, else I get nothing, but they all work.
thanks
