Программа последнего правильного ввода пароля:

#!/usr/local/bin/perl -w dbmopen(%last_good, "lastdb", 0666) || die "can't dbmopen lastdb: $!"; foreach $name (sort keys (%last_good)) { $when = $last_good{$name}; $hours = (time() - $when) / 3600; write; }

format STDOUT = User @&lt&lt&lt&lt&lt&lt&lt&lt&lt&lt: last correct guess was @&lt&lt&lt hour ago. $name, $hours .
