SYNOPSIS
require File::Spec::Epoc; # Done internally by File::Spec if needed
DESCRIPTION
See File::Spec::Unix for a documentation of the methods
provided there. This package overrides the implementation
of these methods, not the semantics.
This package is still work in progress ;-) o.flebbe@gmx.de
devnull
Returns a string representation of the null device.
tmpdir
Returns a string representation of a temporay direc
tory:
path
Takes no argument, returns the environment variable
PATH as an array. Since there is no search path sup
ported, it returns undef, sorry.
canonpath
No physical check on the filesystem, but a logical
cleanup of a path. On UNIX eliminated successive
slashes and successive "/.".
splitpath
($volume,$directories,$file) = File::Spec->splitpath( $path );
($volume,$directories,$file) = File::Spec->splitpath( $path, $no_file );
Splits a path in to volume, directory, and filename
portions. Assumes that the last file is a path unless
the path ends in '\\', '\\.', '\\..' or $no_file is
true. On Win32 this means that $no_file true makes
this return ( $volume, $path, undef ).
Separators accepted are \ and /.
The results can be passed to the catpath entry else
where in this document to get back a path equivalent
to (usually identical to) the original path.
splitdir
The opposite of the catdir() entry elsewhere in this
document.
@dirs = File::Spec->splitdir( $directories );
$directories must be only the directory portion of the
path on systems that have the concept of a volume or
that have path syntax that differentiates files from
directories.
Unlike just splitting the directories on the separa
tor, leading empty and trailing directory entries can
be returned, because these are significant on some
OSs. So,
File::Spec->splitdir( "/a/b/c" );
Yields:
( '', 'a', 'b', '', 'c', '' )
catpath
Takes volume, directory and file portions and returns
an entire path. Under Unix, $volume is ignored, and
this is just like catfile(). On other OSs, the $volume
become significant.
abs2rel
Takes a destination path and an optional base path
returns a relative path from the base path to the des
tination path:
$rel_path = File::Spec->abs2rel( $destination ) ;
$rel_path = File::Spec->abs2rel( $destination, $base ) ;
If $base is not present or '', then the cwd() entry
elsewhere in this document is used. If $base is rela
tive, then it is converted to absolute form using the
rel2abs() entry elsewhere in this document. This means
that it is taken to be relative to the cwd() entry
elsewhere in this document.
On systems with the concept of a volume, this assumes
that both paths are on the $destination volume, and
ignores the $base volume.
On systems that have a grammar that indicates file
names, this ignores the $base filename as well. Other
wise all path components are assumed to be directo
ries.
If $path is relative, it is converted to absolute form
using the rel2abs() entry elsewhere in this document.
This means that it is taken to be relative to the
cwd() entry elsewhere in this document.
Based on code written by Shigio Yamaguchi.
No checks against the filesystem are made.
rel2abs
Converts a relative path to an absolute path.
$abs_path = File::Spec->rel2abs( $destination ) ;
$abs_path = File::Spec->rel2abs( $destination, $base ) ;
If $base is not present or '', then the cwd() entry
elsewhere in this document is used. If $base is rela
tive, then it is converted to absolute form using the
rel2abs() entry elsewhere in this document. This means
that it is taken to be relative to the cwd() entry
elsewhere in this document.
Assumes that both paths are on the $base volume, and
ignores the $destination volume.
On systems that have a grammar that indicates file
names, this ignores the $base filename as well. Other
wise all path components are assumed to be
directories.
If $path is absolute, it is cleaned up and returned
using the canonpath() entry elsewhere in this docu
ment.
Based on code written by Shigio Yamaguchi.
No checks against the filesystem are made.
