|
|
|
|
File::Spec - portably perform operations on file names
|
|
|
|
=head1 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');
|
|
|
|
=head1 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 KE<ouml>nig, 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, L<File::Spec::Functions> provides convenient functional
|
|
forms of these methods.
|
|
|
|
For a list of available methods, please consult L<File::Spec::Unix>,
|
|
which contains the entire set, and which is inherited by the modules for
|
|
other platforms. For further information, please see L<File::Spec::Mac>,
|
|
L<File::Spec::OS2>, L<File::Spec::Win32>, or L<File::Spec::VMS>.
