You know that there's more to MAC addresses than just a sequence of 6 HEX numbers separated by : . But, as vague as you are in your request, this will do:

$ awk 'BEGIN {while (i < 2000) {a=sprintf ("%.12X", i++); gsub(/../,"&:",a); sub(":$","",a); print a}}'
00:00:00:00:00:00
00:00:00:00:00:01
.
.

Thanks for your help. I am not into scripting. Just started with it. Can you tell me how to save the following code and run it into linux.
