in thread Getting the shell's version of working directory, without PWD's help

Please, you should really file a bugreport against Cwd.

Maybe they can't fix cwd() b/c of backwards compatibility but should at least clarify the documentation.

From my POV it's already silly to call two different routines getcwd() and cwd()

So you could suggest to add a new pwd() which always does something like `pwd -L`

    Maybe after I'm more knowledgeable about the actual differences between getcwd() and cwd(). Right now, it's not clear that cwd() should be "fixed". getcwd() tries to call getcwd(3) or reimplements it, while cwd() makes no such promise. And this statement is not strictly wrong: "For most systems it is identical to `pwd` (but without the trailing line terminator)." Though it might benefit the reader to be aware of the difference between pwd -P and pwd -L, and which one the reader is getting with `pwd`.
      Perl should ideally have predictable and consistent behavior across all plattforms and not depend on some shell settings.

      Alone the fact that termux acts differently to ubuntu should ring the alarm bell ...
