`locate`

Here's locate itself:

        use strict 'vars';
        
        $ENV{PATH} = '/bin:/usr/bin';
        
        my $DEF_DB= '/var/lib/slocate/FILES';
        my $DB = $DEF_DB;
        my @GREPFLAGS = ();

        while ($ARGV[0] =~ /^-/) {
          if ($ARGV[0] =~ /^--([^=]*)=(.*)/) {
            if ($1 eq 'database') {
              $DB = $2;
            } else {
              push @GREPFLAGS, $ARGV[0];
            }
          } elsif ($ARGV[0] =~ /^-(.)/) {
            if ($1 eq 'd') {
              $DB = $ARGV[1];
              shift;
            } else {

            }
          } 
          shift;
        }
