in reply to substr problem

I think substr is doing exactly what you're asking it to.

You've set the offset to -1. That means, "Start at the last character on the string." From the last character of the string to the last character + $length characters is still only going to return the last character.

What had you hoped to get instead?

    I was hoping to get a certain number($length) of characters from the end of the string.
    But using -$lenght returns "" regardless of $length.

      so what you need is:
      my $offset = -5; # or however many characters from the end
                 # that you want
my $new_string = substr $filename, $offset;
