file::listing(3)
NAME
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(ISTING, '+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 list
ings,...
The first parameter to parse_dir() is the directory list
ing 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'. Cur
rently only 'unix' is implemented and this is also the
default value. Ideally, the listing type should be deter
mined automatically.
The fourth parameter specifies 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 return value from parse_dir() is a list of directory
entries. In a scalar context the return value is a refer
ence to the list. The directory entries are represented
by an array consisting of [ $filename, $filetype, $file
size, $filetime, $filemode ]. The $filetype value is one
of the letters 'f', 'd', 'l' or '?'. The $filetime value
is the seconds since Jan 1, 1970. The $filemode is a bit
mask like the mode returned by stat().
