It is recommended that getcwd (or another -*cwd() function) be used in I<all> code to ensure portability. - -By default, it exports the functions cwd(), getcwd(), fastcwd(), and -fastgetcwd() (and, on Win32, getdcwd()) into the caller's namespace. - - -=head2 getcwd and friends - -Each of these functions are called without arguments and return the -absolute path of the current working directory. - -=over 4 - -=item getcwd - - my $cwd = getcwd(); - -Returns the current working directory. - -Exposes the POSIX function getcwd(3) or re-implements it if it's not -available. - -=item cwd - - my $cwd = cwd(); - -The cwd() is the most natural form for the current architecture. For -most systems it is identical to `pwd` (but without the trailing line -terminator). - -=item fastcwd - - my $cwd = fastcwd(); - -A more dangerous version of getcwd(), but potentially faster. - -It might conceivably chdir() you out of a directory that it can't -chdir() you back into. If fastcwd encounters a problem it will return -undef but will probably leave you in a different directory. For a -measure of extra security, if everything appears to have worked, the -fastcwd() function will check that it leaves you in the same directory -that it started in. If it has changed it will C<die> with the message -"Unstable directory path, current directory changed -unexpectedly". That should never happen. - -=item fastgetcwd - - my $cwd = fastgetcwd(); - -The fastgetcwd() function is provided as a synonym for cwd(). - -=item getdcwd - - my $cwd = getdcwd(); - my $cwd = getdcwd('C:'); - -The getdcwd() function is also provided on Win32 to get the current working -directory on the specified drive, since Windows maintains a separate current -working directory for each drive. If no drive is specified then the current -drive is assumed. - -This function simply calls the Microsoft C library _getdcwd() function. - -=back - - -=head2 abs_path and friends - -These functions are exported only on request. They each take a single -argument and return the absolute pathname for it. If no argument is -given they'll use the current working directory. - -=over 4 - -=item abs_path - - my $abs_path = abs_path($file); - -Uses the same algorithm as getcwd(). Symbolic links and relative-path -components ("." and "..") are resolved to return the canonical -pathname, just like realpath(3). - -=item realpath - - my $abs_path = realpath($file); - -A synonym for abs_path(). - -=item fast_abs_path - - my $abs_path = fast_abs_path($file); - -A more dangerous, but potentially faster version of abs_path. - -=back - -=head2 $ENV{PWD} - -If you ask to override your chdir() built-in function, - - use Cwd qw(chdir); - -then your PWD environment variable will be kept up to date. Note that -it will only be kept up to date if all packages which use chdir import -it from Cwd. - - -=head1 NOTES - -=over 4 - -=item * - -Since the path seperators are different on some operating systems ('/' -on Unix, ':' on MacPerl, etc...) we recommend you use the File::Spec -modules wherever portability is a concern. - -=item * - -Actually, on Mac OS, the C<getcwd()>, C<fastgetcwd()> and C<fastcwd()> -functions are all aliases for the C<cwd()> function, which, on Mac OS, -calls `pwd`. Likewise, the C<abs_path()> function is an alias for -C<fast_abs_path()>. - -=back - -=head1 AUTHOR - -Originally by the perl5-porters. - -Maintained by Ken Williams <KWILLIAMS@cpan.org> - -=head1 COPYRIGHT - -Copyright (c) 2004 by the Perl 5 Porters.
