Thanks,

Try:
$ perl -e'
$str = "asdfggfh 987321qwertyyy\n";
($num = $str) =~ s/^.*?(\d+).*$/$1/s;
print $num;
' | hd
See `perldoc perlre` and search for /Modifiers/. Read the section on
the /s modifier.

Confusion is the first step of understanding.
Programming is as much about organization and communication

The secret to great software: Fail early & often.
Eliminate software piracy: use only FLOSS.
