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.
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 Koenig, 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 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, please consult the
File::Spec::Unix manpage, which contains the entire set, and
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.
