It seemed to me that nobody would ever say "IEEEIX", since the pronunciation would sound like a shriek of terror; rather, everyone would call it "Unix". That would have boosted AT&T, the GNU Project's rival, an outcome I did not want. So I looked for another name, but nothing natural suggested itself to me.<p>So I put the initials of "Portable Operating System" together with the same suffix "ix", and came up with "POSIX". It sounded good and I saw no reason not to use it, so I suggested it. Although it was just barely in time, the committee adopted it. 
"<p>so, as can be seen, posix is RMS's way of keeping people from calling unix unix, 
and as a result today, now that AT&T Unix is nearly dead,
people lose track of the fact that BSD <i>is</i> Unix, and don't know what Unix actually is, and are forced to 'decode' the sometimes deliberately less clear cloned sources not knowing to look at the simpler original.
