I'm an old Unix geezer.
I've administered Esix System V R3.2, SCO Xenix, SCO Unix, SunOS 4.x, Solaris 2+, FreeBSD, Slackware Linux, RedHat Linux, AIX, and HP-UX. I've used a lot more Unixes than I've administered.
At one time, I was an AIX admin for IBM. I am also certified in Solaris and HP-UX. Most of my work is currently done under Red Hat Enterprise Linux, although I am switching back to FreeBSD as soon as is humanly possible.
The FAQ has a Unix section, but no Windows section. The Forum has a Windows section, but no Unix section. Isn't that incongruous?
No one seems to ask Unix questions.
But, I will create a Unix forum and we will see if we can make it popular!
