Code and explanation of a Trim function for the Perl Programming language.

There is a simple function you can build to trim strings in your Perl programs.
The function uses two regular expressions to trim a string from the left side of the string as well as one for the right side.

	Code Snippet 1

#!/usr/bin/perl -w

# Perl trim function

sub trimStr($){

my $string = shift;
           # the first regular expression removes space
           # from the left side
$string =~ s/^\s+//;
           # the second regular expression removes space
           # from the right side
$string =~ s/\s+$//;

return $string;

}

exit 0;
