parse_dir - parse directory listing
SYNOPSIS
use File::Listing;
for (parse_dir(`ls -l`)) {
($name, $type, $size, $mtime, $mode) = @$_;
next if $type ne 'f'; # plain file
#...
}
# directory listing can also be read from a file
open(LISTING, "zcat ls-lR.gz|");
$dir = parse_dir(\*LISTING, '+0000');
DESCRIPTION
The parse_dir() routine can be used to parse directory
listings. Currently it only understand Unix 'ls -l' and
'ls -lR' format. It should eventually be able to most
things you might get back from a ftp server file listing
(LIST command), i.e. VMS listings, NT listings, DOS
listings,...
The first parameter to parse_dir() is the directory
listing to parse. It can be a scalar, a reference to an
array of directory lines or a glob representing a
filehandle to read the directory listing from.
The second parameter is the time zone to use when parsing
time stamps in the listing. If this value is undefined,
then the local time zone is assumed.
The third parameter is the type of listing to assume. The
values will be strings like 'unix', 'vms', 'dos'.
Currently only 'unix' is implemented and this is also the
default value. Ideally, the listing type should be
determined automatically.
The fourth parameter specify how unparseable lines should
be treated. Values can be 'ignore', 'warn' or a code
reference. Warn means that the perl warn() function will
be called. If a code reference is passed, then this
routine will be called and the return value from it will
be incorporated in the listing. The default is 'ignore'.
Only the first parameter is mandatory. The parse_dir()
prototype is ($;$$$).
The return value from parse_dir() is a list of directory
entries. In scalar context the return value is a
reference to the list. The directory entries are
represented by an array consisting of [ $filename,
$filetype, $filesize, $filetime, $filemode ]. The

$filetype value is one of the letters 'f', 'd', 'l' or
'?'. The $filetime value is converted to seconds since
Jan 1, 1970. The $filemode is a bitmask like the mode
returned by stat().
