22 File::Spec - portably perform operations on file names
28 $x=File::Spec->catfile('a', 'b', 'c');
30 which returns 'a/b/c' under Unix. Or:
32 use File::Spec::Functions;
34 $x = catfile('a', 'b', 'c');
38 This module is designed to support operations commonly performed on file
39 specifications (usually called "file names", but not to be confused with the
40 contents of a file, or Perl's file handles), such as concatenating several
41 directory and file names into a single path, or determining whether a path
42 is rooted. It is based on code directly taken from MakeMaker 5.17, code
43 written by Andreas KE<ouml>nig, Andy Dougherty, Charles Bailey, Ilya
44 Zakharevich, Paul Schinder, and others.
46 Since these functions are different for most operating systems, each set of
47 OS specific routines is available in a separate module, including:
55 The module appropriate for the current OS is automatically loaded by
56 File::Spec. Since some modules (like VMS) make use of facilities available
57 only under that OS, it may not be possible to load all modules under all
60 Since File::Spec is object oriented, subroutines should not called directly,
63 File::Spec::catfile('a','b');
65 but rather as class methods:
67 File::Spec->catfile('a','b');
69 For simple uses, L<File::Spec::Functions> provides convenient functional
70 forms of these methods.
72 For a list of available methods, please consult L<File::Spec::Unix>,
73 which contains the entire set, and which is inherited by the modules for
74 other platforms. For further information, please see L<File::Spec::Mac>,
75 L<File::Spec::OS2>, L<File::Spec::Win32>, or L<File::Spec::VMS>.
