File::Spec

See the current Perl documentation for File::Spec.

Here is our local, out-dated (pre-5.6) version:


File::Spec - portably perform operations on file names



use File::Spec;

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

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



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:

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

The module appropriate for the current OS is automatically loaded by File::Spec. Since some modules (like VMS) make use of OS specific facilities, 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 a reference of available functions, pleaes consult Spec_Unix, which contains the entire set, and inherited by the modules for other platforms. For further information, please see Spec::Mac, Spec::OS2, Spec::Win32, or Spec::VMS.
