Hi. Chris,

I found the latest inetutils-1.3.2-7 has the same behaviour.

$ ftp localhost
   .......
ftp> pwd
550 Invalid argument.

inetutils-1.3.2/ftpd/ftpd.c also relys on this bug.

$ grep getpwd ftpd.c
        path = getcwd (0, 0);
                char *cwd = getcwd (0, 0);
        char *path = getcwd (0, 0);

The ftpd should be fixed, I think.

Regards,
Takashi Nishigaya
