Wow, today I logged into my first AIX Server in about 4.5 years. It was a horrible experience. I've been working with Redhat/CentOS pretty much exculsively for so long, I was mostly helpless to do anything of importance on the CLI other than create a few users and move some files around. None of the common commands that I am so used to using even exist in AIX.
