in thread Wanted: humanly readable `script` output

Not really. Consider:

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

Prints:

No good

    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 ~]$
