## NAME

File::Spec - portably perform operations on file names

## SYNOPSIS

    	use File::Spec;

    	$x=File::Spec->catfile('a', 'b', 'c');

    which returns 'a/b/c' under Unix. Or:

    	use File::Spec::Functions;

    	$x = catfile('a', 'b', 'c');

## DESCRIPTION

This module is designed to support operations commonly performed on file specifications (usually called "file names", but not to be confused with the contents of a file, or Perl's file handles), such as concatenating several directory and file names into a single path, or determining whether a path is rooted. It is based on code directly taken from MakeMaker 5.17, code written by Andreas König, Andy Dougherty, Charles Bailey, Ilya Zakharevich, Paul Schinder, and others.

    Since these functions are different for most operating systems, each set of
    OS specific routines is available in a separate module, including:

    	File::Spec::Unix
    	File::Spec::Mac
    	File::Spec::OS2
    	File::Spec::Win32
    	File::Spec::VMS

The module appropriate for the current OS is automatically loaded by File::Spec. Since some modules (like VMS) make use of facilities available only under that OS, it may not be possible to load all modules under all operating systems.

    Since File::Spec is object oriented, subroutines should not called directly,
    as in:

    	File::Spec::catfile('a','b');

    but rather as class methods:

    	File::Spec->catfile('a','b');

For simple uses, the File::Spec::Functions manpage provides convenient functional forms of these methods.

For a list of available methods, please consult the File::Spec::Unix manpage, which contains the entire set, and which is inherited by the modules for other platforms. For further information, please see the File::Spec::Mac manpage, the File::Spec::OS2 manpage, the File::Spec::Win32 manpage, or the File::Spec::VMS manpage.
