I read somewhere (probably in the CookBook) that it's faster to execute this :

$string=~s/^\s+//;
$string=~s/\s+$//;
[download]

Than the one-liner :

$string =~ s/^\s+|\s+$//g;

Note that the `/g` in the two line example are pointless. There's no need to repeatedly remove all whitespace at the front or end. Abigail	[reply]
