NAME

File::Listing - Parse directory listing

VERSION

version 6.14

SYNOPSIS

use File::Listing qw(parse_dir);
     $ENV{LANG} = "C";  # dates in non-English locales not supported
     foreach my $file (parse_dir(`ls -l`)) {
         my ($name, $type, $size, $mtime, $mode) = @$file;
         next if $type ne 'f'; # plain file
         #...
     }
     
     # directory listing can also be read from a file
     open my $listing, "zcat ls-lR.gz|";
     $dir = parse_dir($listing, '+0000');

DESCRIPTION

This module exports a single function called parse_dir, which can be
    used to parse directory listings.

FUNCTIONS

parse_dir

my $dir = parse_dir( $listing );
     my $dir = parse_dir( $listing, $time_zone );
     my $dir = parse_dir( $listing, $time_zone, $type );
     my $dir = parse_dir( $listing, $time_zone, $type, $error );
     my @files = parse_dir( $listing );
     my @files = parse_dir( $listing, $time_zone );
     my @files = parse_dir( $listing, $time_zone, $type );
     my @files = parse_dir( $listing, $time_zone, $type, $error );

The first parameter ($listing) 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 ($time_zone) 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 ($type) is the type of listing to assume. Currently
    supported formats are 'unix', 'apache' and 'dosftp'. The default value
    is 'unix'. Ideally, the listing type should be determined
    automatically.

The fourth parameter ($error) 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.

# list context
     foreach my $file (parse_dir($listing)) {
         my($name, $type, $size, $mtime, $mode) = @$file;
     }
     
     # scalar context
     my $dir = parse_dir($listing);
     foreach my $file (@$dir) {
         my($name, $type, $size, $mtime, $mode) = @$file;
     }

The return value from parse_dir() is a list of directory entries. In a
    scalar context the return value is a reference to the list. The
    directory entries are represented by an array consisting of:

name

The name of the file.

type

One of: f file, d directory, l symlink, ? unknown.

size

The size of the file.

time

The number of seconds since January 1, 1970.

mode

Bitmask a la the mode returned by stat.
