You can replace the while loop with this little regex:
$text =~ s/.\x08//g;

    Not really. Consider:

    my $text = "No \x08\x08\x08 good"; $text =~ s/.\x08//g; print $text;


    No good

    Perl is environmentally friendly - it saves trees

      This problem with the way /g works is fixed with the 1 while hack

      [james@adajio ~]$ cat #!/usr/bin/perl my $text = "No \x08\x08\x08 good"; 1 while $text =~ s/.\x08//; print "$text\n"; [james@adajio ~]$ ./ good [james@adajio ~]$
