On our systems, one can get a decent idea of where one is more than half the time: If (bogomips ~= 14037) Processor = z196 && OS = SLES 11 Elif (bogomips ~= 11061) Processor = z10 && OS = SLES 11 or RHEL 6 Elif (bogomips ~= 2800) Processor = z196 && OS = SLES 10 Elif (b

Cuteness, with the exception of small kittens, is in the eye of the beholder. However, you'll want to leave that whole text in your script as a comment because it isn't obvious what that pile is or why you did it. At least it sure wasn't obvious to me. It is, however, efficient. I tried a co
