$ # list the files in current directory
$ ls -1
MQS_MT535_A1b2X_20100831_blah
MQS_MT535_PQ9rs_20100831_blah

     4  opendir (my $dh, $some_dir) || die "Can't opendir $some_dir: $!";
     5  @files = grep {/$pattern/x} readdir($dh);
     6  print $_,"\n" for (@files);
     7  closedir ($dh) || die "Can't closedir $some_dir: $!";

RIG(6)								   Games Manual 							    RIG(6)

NAME

       RIG - Random Identity Generator

USAGE

       rig [ -f | -m ] [ -d datadir ] [ -c num ]

DESCRIPTION

       Rig is a utility that will piece together a random first name, last name, street number and address, along with a geographically consistant
       (ie, they all match the same area) city, state, ZIP code, and area code.

       It is suitable for such applications as feeding the NY times registration page to fend off junk (snail) mail and telemarketers, or for reg-
       istering on BBS's to which you don't wish to reveal your real information.

OPTIONS

       -f, -m Respectively, use female and male names. If neither or both options are selected, RIG uses both female and male names.

       -d datadir
	      Use data files found in datadir. Without this option, the default directory of /usr/share/rig is assumed.

       -c num Output num identities. Default is 1.

FILES

       /usr/share/rig/locdata.idx
       /usr/share/rig/street.idx
       /usr/share/rig/fnames.idx
       /usr/share/rig/mnames.idx
       /usr/share/rig/lnames.idx

HISTORY

       Based on "fake" written for MS-DOS. Unfortunately the author and publish date are unknown.

       First UNIX version written from scratch in 1999.

       This manpage based on RIG version 1.10.

       original  version  and  I  believe  it  to  be  held   in   the	 public   domain.    Names   database	is   from   the   US   Census	at
