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;

    Prints:

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