I don't remember now either lol. I can revert the revert though. Is it POSIX 2018 or POSIX 2017 now? On the site, it has:
```
The Open Group Base Specifications Issue 7, 2018 edition
IEEE Std 1003.1™-2017 (Revision of IEEE Std 1003.1-2008)
```
at the top, but I don't know the different between the top and the bottom.
