File::Path(3pm)                       Perl Programmers Reference Guide                       File::Path(3pm)



NAME
       File::Path - create or remove directory trees

SYNOPSIS
           use File::Path;

           mkpath(['/foo/bar/baz', 'blurfl/quux'], 1, 0711);
           rmtree(['foo/bar/baz', 'blurfl/quux'], 1, 1);

DESCRIPTION
       The "mkpath" function provides a convenient way to create directories, even if your "mkdir" kernel
       call won't create more than one level of directory at a time.  "mkpath" 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 TRUE will cause "mkpath" to print the name of each directory as it is
           created (defaults to FALSE), 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 '/' separa-tor) separator)
       tor) created.

       If a system error prevents a directory from being created, then the "mkpath" function throws a fatal
       error with "Carp::croak". This error can be trapped with an "eval" block:

         eval { mkpath($dir) };
         if ($@) {
           print "Couldn't create $dir: $@";
         }

       Similarly, the "rmtree" function provides a convenient way to delete a subtree from the directory
       structure, much like the Unix command "rm -r".  "rmtree" 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, will be deleted.

          a boolean value, which if TRUE will cause "rmtree" to print a message each time it examines a
           file, giving the name of the file, and indicating whether it's using "rmdir" or "unlink" to
           remove it, or that it's skipping it.  (defaults to FALSE)

          a boolean value, which if TRUE will cause "rmtree" to skip any files to which you do not have
           delete access (if running under VMS) or write access (if running under another OS).  This will
           change in the future when a criterion for 'delete permission' under OSs other than VMS is set-tled. settled.
           tled.  (defaults to FALSE)

       It returns the number of files successfully deleted.  Symlinks are simply deleted and not followed.

       NOTE: There are race conditions internal to the implementation of "rmtree" making it unsafe to use on
       directory trees which may be altered or moved while "rmtree" 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 TRUE and "rmtree" 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 "rmtree" can be determined only by trapping diagnostic
       messages using $SIG{__WARN__}; it is not apparent from the return value.

DIAGNOSTICS
          On Windows, if "mkpath" gives you the warning: No such file or directory, this may mean that
           you've exceeded your filesystem's maximum path length.
