#            This Perl program is intended to illustrate how one reads
#            UNIX directories(filenames in a subdirectory) with readdir.
#            Perl's glob function makes this method a bit archaic if
#            all one wants to do is to know the names of files in some
#            directory...

$dirToRead = shift(@ARGV);

# Open the directory handle
opendir(DH, $dirToRead) || die "Could not open up $dirToRead\n";

# Read the directory entries.  Perl's readdir function will read
# ALL the entries if it is called in a list context.  Kool!
@dirEnts = readdir(DH);
closedir(DH);

# No loop was required to read the data, so we have
# a loop here to print it all out. :)
foreach $dirEnt (@dirEnts) {
  printf("File: %s\n", $dirEnt);
