in thread remove first and last character of string

Thanks Rob, but is there a way use this Or remove the last character of $str : substr($str, length($str) - 1, '') to remove the last and first in one line?

    Win8 Strawberry 5.8.9.5 (32) Tue 10/13/2020 23:18:23 C:\@Work\Perl\monks >perl -Mstrict -Mwarnings my $s = '"654321_1111"'; print "'$s' \n"; $s = substr $s, 1, -1; print "'$s' \n"; ^Z '"654321_1111"' '654321_1111'


    Give a man a fish:  <%-{-{-{-<

      $s = substr $s, 1, -1;

      Nice.
      I didn't know that would work. I would have done it as:
      $s = substr $s, 1, length($s) - 2;
      But I've read the documentation, now ;-)

      Cheers,
      Rob
