Re: Sequentially numbering output files rather than overwriting an existing file

For the first unused "$name$n.txt" file:

if (-f "$name.txt") {
    $n=1;
    $n++ while -f "$name$n.txt";
}

For one greater than the highest "$name$n.txt" file, something like kcott's solution below works.

For more visually pleasing output: `if (-f "$name.txt") { $n=1; my $fn = sprintf "%s-%05d\.txt", $name, $n; $n++ while -f $fn; }` [download]	[reply] [d/l]
