.TH File::Path 3 "2001-09-21" "perl v5.8.8" "Perl Programmers Reference Guide"
File::Path \- create or remove directory trees
\& mkpath(['/foo/bar/baz', 'blurfl/quux'], 1, 0711);
\& rmtree(['foo/bar/baz', 'blurfl/quux'], 1, 1);
The \f(CW\*(C`mkpath\*(C'\fR function provides a convenient way to create directories, even
if your \f(CW\*(C`mkdir\*(C'\fR kernel call won't create more than one level of directory at
a time. \f(CW\*(C`mkpath\*(C'\fR takes three arguments:
the name of the path to create, or a reference
to a list of paths to create,
a boolean value, which if \s-1TRUE\s0 will cause \f(CW\*(C`mkpath\*(C'\fR
to print the name of each directory as it is created
(defaults to \s-1FALSE\s0), and
the numeric mode to use when creating the directories
(defaults to 0777), to be modified by the current umask.
It returns a list of all directories (including intermediates, determined
using the Unix '/' separator) created.
If a system error prevents a directory from being created, then the
\&\f(CW\*(C`mkpath\*(C'\fR function throws a fatal error with \f(CW\*(C`Carp::croak\*(C'\fR. This error
can be trapped with an \f(CW\*(C`eval\*(C'\fR block:
\& eval { mkpath($dir) };
\& print "Couldn't create $dir: $@";
Similarly, the \f(CW\*(C`rmtree\*(C'\fR function provides a convenient way to delete a
subtree from the directory structure, much like the Unix command \f(CW\*(C`rm \-r\*(C'\fR.
\&\f(CW\*(C`rmtree\*(C'\fR takes three arguments:
the root of the subtree to delete, or a reference to
a list of roots. All of the files and directories
below each root, as well as the roots themselves,
a boolean value, which if \s-1TRUE\s0 will cause \f(CW\*(C`rmtree\*(C'\fR to
print a message each time it examines a file, giving the
name of the file, and indicating whether it's using \f(CW\*(C`rmdir\*(C'\fR
or \f(CW\*(C`unlink\*(C'\fR to remove it, or that it's skipping it.
(defaults to \s-1FALSE\s0)
a boolean value, which if \s-1TRUE\s0 will cause \f(CW\*(C`rmtree\*(C'\fR to
skip any files to which you do not have delete access
(if running under \s-1VMS\s0) or write access (if running
under another \s-1OS\s0). This will change in the future when
a criterion for 'delete permission' under OSs other
than \s-1VMS\s0 is settled. (defaults to \s-1FALSE\s0)
It returns the number of files successfully deleted. Symlinks are
simply deleted and not followed.
\&\fB\s-1NOTE:\s0\fR There are race conditions internal to the implementation of
\&\f(CW\*(C`rmtree\*(C'\fR making it unsafe to use on directory trees which may be
altered or moved while \f(CW\*(C`rmtree\*(C'\fR is running, and in particular on any
directory trees with any path components or subdirectories potentially
writable by untrusted users.
Additionally, if the third parameter is not \s-1TRUE\s0 and \f(CW\*(C`rmtree\*(C'\fR is
interrupted, it may leave files and directories with permissions altered
to allow deletion (and older versions of this module would even set
files and directories to world\-read/writable!)
Note also that the occurrence of errors in \f(CW\*(C`rmtree\*(C'\fR can be determined \fIonly\fR
by trapping diagnostic messages using \f(CW$SIG{_\|_WARN_\|_}\fR; it is not apparent
On Windows, if \f(CW\*(C`mkpath\*(C'\fR gives you the warning: \fBNo such file or
directory\fR, this may mean that you've exceeded your filesystem's
