# NAME

getcwd - get pathname of current working directory

# SYNOPSIS

        use Cwd;
        $dir = cwd;

        use Cwd;
        $dir = getcwd;

        use Cwd;
        $dir = fastgetcwd;

        use Cwd 'chdir';
        chdir "/tmp";
        print $ENV{'PWD'};

# DESCRIPTION

The `getcwd()` function re-implements the `getcwd(3)` (or `getwd(3))` functions in Perl.

The `fastcwd()` function looks the same as `getcwd(),` but runs faster. It's also more dangerous because you might conceivably `chdir()` out of a directory that you can't `chdir()` back into.

The `cwd()` function looks the same as getcwd and fastgetcwd but is implemented using the most natural and safe form for the current architecture. For most systems it is identical to `pwd` (but without the trailing line terminator). It is recommended that cwd (or another *cwd() function) is used in all code to ensure portability.

If you ask to override your `chdir()` built-in function, then your PWD environment variable will be kept up to date. (See Overriding Builtin Functions.) Note that it will only be kept up to date if all packages which use chdir import it from Cwd.
