Do you mean the Single Unix Specification? – Andrew Lambert Feb 29 '12 at 8:18
I think that's it, bro. – Eroen Feb 29 '12 at 8:20
No, I mean the POSIX standard. It's a different organisation (although specifications overlap). – Andrew J. Brehm Feb 29 '12 at 8:54
Well,the Wikipedia article lists many more, or are you looking for a special certification? – slhck Feb 29 '12 at 11:37
No, the Wikipedia article points to the list linked above. – Eroen Feb 29 '12 at 17:59
