5 File::Path - create or remove a series of directories
11 C<mkpath(['/foo/bar/baz', 'blurfl/quux'], 1, 0711);>
13 C<rmtree(['foo/bar/baz', 'blurfl/quux'], 1, 1);>
17 The C<mkpath> function provides a convenient way to create directories, even if
18 your C<mkdir> kernel call won't create more than one level of directory at a
19 time. C<mkpath> takes three arguments:
25 the name of the path to create, or a reference
26 to a list of paths to create,
30 a boolean value, which if TRUE will cause C<mkpath>
31 to print the name of each directory as it is created
32 (defaults to FALSE), and
36 the numeric mode to use when creating the directories
41 It returns a list of all directories (including intermediates, determined using
42 the Unix '/' separator) created.
44 Similarly, the C<rmtree> function provides a convenient way to delete a
45 subtree from the directory structure, much like the Unix command C<rm -r>.
46 C<rmtree> takes three arguments:
52 the root of the subtree to delete, or a reference to
53 a list of roots. All of the files and directories
54 below each root, as well as the roots themselves,
59 a boolean value, which if TRUE will cause C<rmtree> to
60 print a message each time it examines a file, giving the
61 name of the file, and indicating whether it's using C<rmdir>
62 or C<unlink> to remove it, or that it's skipping it.
67 a boolean value, which if TRUE will cause C<rmtree> to
68 skip any files to which you do not have delete access
69 (if running under VMS) or write access (if running
70 under another OS). This will change in the future when
71 a criterion for 'delete permission' under OSs other
72 than VMS is settled. (defaults to FALSE)
76 It returns the number of files successfully deleted. Symlinks are
77 treated as ordinary files.
