NAME¶
File::Listing - parse directory listing
SYNOPSIS¶
use File::Listing qw(parse_dir);
$ENV{LANG} = "C"; # dates in non-English locales not supported
for (parse_dir(`ls -l`)) {
($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¶
This module exports a single function called
parse_dir(), which can be
used to parse directory 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. Currently supported
formats are 'unix', 'apache' and 'dosftp'. The default value is 'unix'.
Ideally, the listing type should be determined 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 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 the seconds since Jan 1, 1970.
The $filemode is a bitmask like the mode returned by
stat().
