This was a recently-added question to the FAQ (in perlfaq5, under the
title "Why do I get weird spaces when I print an array of lines?
Why not using chomp instead?
from perlfunc:
"This safer version of chop removes any trailing string that
corresponds to the current value of $/ ..."

Well, I think a regex is your best bet.
---
$data = 'This is a very long string ';
$data =~ s/\s+$//;

That will trim all trailing spaces.
Without a regex you could try something like
---
$data = 'This is a very long string ';
do {
$_ = $data;
$test = chop;

There's also:
$foo =~ s/^\s*//;
and if you want to strip leading and trailing spaces:
$foo =~ s/^\s*(.*?)\s*$/$1/;
Though some say that the two step:
$foo =~ s/^\s*//;
$foo =~ s/\s*$//;

String::Strip
with a function
StripLTSpace()

Hello,
Of course this regex only removes the leading spaces only, or the
trailing spaces if there are no leading spaces.
You can use
$string =~ s/^ +| +$//g; # g for global matches
or do it in 2 steps:
$str =~ s/^ +//;
$str =~ s/ +$//;
Hope this helps,,,
