NAME

File::Spec::Link - Perl extension for reading and resolving symbolic links

SYNOPSIS

    use File::Spec::Link;
    my $file = File::Spec::Link->linked($link); 
    my $file = File::Spec::Link->resolve($link); 
    my $dirname = File::Spec::Link->chopfile($file);
    my $newname = File::Spec::Link->relative_to_file($path, $link);
  
    my $realname = File::Spec::Link->full_resolve($file);

DESCRIPTION

File::Spec::Link is an extension to File::Spec, adding methods for resolving symbolic links; it was created to implement File::Copy::Link.

->linked($link)

Returns the filename linked to by $link: by readlinking $link, and resolving that path relative to the directory of $link.

->resolve($link)

Returns the non-link ultimately linked to by $link, by repeatedly calling linked. Returns undef if the link can not be resolved.

->chopfile($file)

Returns the directory of $file, by splitting the path of $file and returning (the volumne and) directory parts.

->relative_to_file($path, $file)

Returns the path of $path relative to the directory of file $file. If $path is absolute, just returns $path.

->full_resolve($file)

Returns the filename of $file with all links in the path resolved.

This sub uses Cwd::abs_path and is independent of the rest of File::Spec::Link.

EXPORT

None - all subs are class methods for File::Spec::Link.
