MSDOS::Attrib - Get or set MS-DOS file attributes
This document describes version 1.06 of MSDOS::Attrib, released September 6, 2014.
use MSDOS::Attrib qw(get_attribs set_attribs); $attribs = get_attribs($path); set_attribs($attribs, $path1, $path2, ...);
MSDOS::Attrib provides access to MS-DOS file attributes. While the read-only attribute can be handled by
stat, the hidden, system, and archive attributes cannot.
Returns the attributes of
$path, or the empty string if
$path does not exist. Attributes are returned as a five-character string in this format: "RHSAD". Each letter is replaced by an underscore (
_) if the file does not have the corresponding attribute. (This is the same format as a 4DOS directory listing.) The attributes are:
R The file is read-only (not writable) H The file is hidden (does not appear in directory listings) S The file is a system file (does not appear in directory listings) A The file needs to be archived (it has changed since last backup) D The file is a directory
Sets the attributes of
$path2, etc. You can either specify the complete set of attributes, or add and subtract attributes by using
-. The case and order of the attributes is not important. For example, '-s+ra' will remove the system attribute and add the read-only and archive attributes. You should not use whitespace between attributes, although underscores are OK. See
get_attribs for an explanation of the attribute values. You cannot change the directory attribute; if you specify it, it is ignored. Returns the number of files successfully changed.
The OS2::ExtAttr module provides access to extended attributes under OS/2.
The Win32::FileSecurity module provides access to Discretionary Access Control Lists under Windows NT.
MSDOS::Attrib requires no configuration files or environment variables.
No bugs have been reported.
