Note: help and version output are generated by a naïve script which tries a few variants of
<command> --help, <command> -h etc. to find the command's help and version info.
Sometimes it gets lucky, sometimes it doesn't; if the output below looks wrong, it probably is.
pwdx --version (return code: 0)
pwdx from procps-ng 3.3.10
pwdx --help (return code: 0)
pwdx [options] pid...
-h, --help display this help and exit
-V, --version output version information and exit
For more details see pwdx(1).
