\D is a shorcut for [^0123456789] (any non digit)
You could remove " lines processed" like this:
$string = "50 lines processed";
$string =~ s/\D//g; #substitute any non-number character with nothing
if you are reading lines and want to not process lines that have
non-numeric elements try this:
while (<IN>) {
continue if (/\D/);
process($_);
}
