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 be 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. - -=head1 METHODS - -=over 2 - -=item canonpath - -No physical check on the filesystem, but a logical cleanup of a -path. - - $cpath = File::Spec->canonpath( $path ) ; - -Note that this does *not* collapse F<x/../y> sections into F<y>. This -is by design. If F</foo> on your system is a symlink to F</bar/baz>, -then F</foo/../quux> is actually F</bar/quux>, not F</quux> as a naive -F<../>-removal would give you. If you want to do this kind of -processing, you probably want C<Cwd>'s C<realpath()> function to -actually traverse the filesystem cleaning up paths like this. - -=item catdir - -Concatenate two or more directory names to form a complete path ending -with a directory. But remove the trailing slash from the resulting -string, because it doesn't look good, isn't necessary and confuses -OS/2. Of course, if this is the root directory, don't cut off the -trailing slash :-) - - $path = File::Spec->catdir( @directories ); - -=item catfile - -Concatenate one or more directory names and a filename to form a -complete path ending with a filename - - $path = File::Spec->catfile( @directories, $filename ); - -=item curdir - -Returns a string representation of the current directory. - - $curdir = File::Spec->curdir(); - -=item devnull - -Returns a string representation of the null device. - - $devnull = File::Spec->devnull(); - -=item rootdir - -Returns a string representation of the root directory. - - $rootdir = File::Spec->rootdir(); - -=item tmpdir - -Returns a string representation of the first writable directory from a -list of possible temporary directories. Returns the current directory -if no writable temporary directories are found. The list of directories -checked depends on the platform; e.g. File::Spec::Unix checks C<$ENV{TMPDIR}> -(unless taint is on) and F</tmp>. - - $tmpdir = File::Spec->tmpdir(); - -=item updir - -Returns a string representation of the parent directory. - - $updir = File::Spec->updir(); - -=item no_upwards - -Given a list of file names, strip out those that refer to a parent -directory. (Does not strip symlinks, only '.', '..', and equivalents.) - - @paths = File::Spec->no_upwards( @paths ); - -=item case_tolerant - -Returns a true or false value indicating, respectively, that alphabetic -case is not or is significant when comparing file specifications. - - $is_case_tolerant = File::Spec->case_tolerant(); - -=item file_name_is_absolute - -Takes as its argument a path, and returns true if it is an absolute path. - - $is_absolute = File::Spec->file_name_is_absolute( $path ); - -This does not consult the local filesystem on Unix, Win32, OS/2, or -Mac OS (Classic). It does consult the working environment for VMS -(see L<File::Spec::VMS/file_name_is_absolute>). - -=item path - -Takes no argument. Returns the environment variable C<PATH> (or the local -platform's equivalent) as a list. - - @PATH = File::Spec->path(); - -=item join - -join is the same as catfile. - -=item splitpath - -Splits a path in to volume, directory, and filename portions. On systems -with no concept of volume, returns '' for volume. - - ($volume,$directories,$file) = File::Spec->splitpath( $path ); - ($volume,$directories,$file) = File::Spec->splitpath( $path, $no_file ); - -For systems with no syntax differentiating filenames from directories, -assumes that the last file is a path unless C<$no_file> is true or a -trailing separator or F</.> or F</..> is present. On Unix, this means that C<$no_file> -true makes this return ( '', $path, '' ). - -The directory portion may or may not be returned with a trailing '/'. - -The results can be passed to L</catpath()> to get back a path equivalent to -(usually identical to) the original path. - -=item splitdir - -The opposite of L</catdir()>. - - @dirs = File::Spec->splitdir( $directories ); - -C<$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 separator, empty -directory names (C<''>) can be returned, because these are significant -on some OSes. - -=item catpath() - -Takes volume, directory and file portions and returns an entire path. Under -Unix, C<$volume> is ignored, and directory and file are concatenated. A '/' is -inserted if need be. On other OSes, C<$volume> is significant. - - $full_path = File::Spec->catpath( $volume, $directory, $file ); - -=item abs2rel - -Takes a destination path and an optional base path returns a relative path -from the base path to the destination path: - - $rel_path = File::Spec->abs2rel( $path ) ; - $rel_path = File::Spec->abs2rel( $path, $base ) ; - -If C<$base> is not present or '', then L<cwd()|Cwd> is used. If C<$base> is -relative, then it is converted to absolute form using -L</rel2abs()>. This means that it is taken to be relative to -L<cwd()|Cwd>. - -On systems with the concept of volume, if C<$path> and C<$base> appear to be -on two different volumes, we will not attempt to resolve the two -paths, and we will instead simply return C<$path>. Note that previous -versions of this module ignored the volume of C<$base>, which resulted in -garbage results part of the time. - -On systems that have a grammar that indicates filenames, this ignores the -C<$base> filename as well. Otherwise all path components are assumed to be -directories. - -If C<$path> is relative, it is converted to absolute form using L</rel2abs()>. -This means that it is taken to be relative to L<cwd()|Cwd>. - -No checks against the filesystem are made. On VMS, there is -interaction with the working environment, as logicals and -macros are expanded. - -Based on code written by Shigio Yamaguchi. - -=item rel2abs() - -Converts a relative path to an absolute path. - - $abs_path = File::Spec->rel2abs( $path ) ; - $abs_path = File::Spec->rel2abs( $path, $base ) ; - -If C<$base> is not present or '', then L<cwd()|Cwd> is used.
