If you need to produce a sequence of sequential or random numbers on a Mac OS X or Linux system among the options available to you are the seq or jot commands, or you can use "brace expansion".
Seq
E.g., if you want to generate the numbers from 1 to 15 in increments of 1, you could use the seq command below:$ seq 1 15 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
