Rosetta Stone for UNIX

Know AIX? Ever wonder what that simple command in AIX is on Solaris or HP/UX? Need to know what the command for tcp/ip management is in Linux compared to OS/X? Now you can! Check out this helpful website Rosetta Stone for UNIX. My boss passed this along a while ago and I thought I had passed it along to the community, but I cannot remember if I did. So, here is a great website for UNIX admins and those learning UNIX to help you transition from one vendor to another.
