I believe /proc came from Plan 9. However, it's not a standard Unix feature. Last time I checked it was optional on FreeBSD and disabled by default. The FreeBSD version is also different from the Linux version, sufficiently so that there's a second /proc for the Linux emulation layer.  And like Andrew, I find no /proc on my Macs.

Unlike the free unices. Makes it a good platform for developing Unix software on.
