- From your example it appears that you want to remove all whitespace from
the beginning, and end, and duplicates from inside. You can achieve this
easily:
my $text = ' the description of the file ';
for($text) {
s/^\s+//;
s/\s+$//;
# Perhaps its more effecient to put this next line first?
s/\s+/ /g;
}
Also, check "perldoc -q space".
