1. Could you please show what you have tried?

2. Please understand that forum members may not have working knowledge of biology. So when you say, "Print out the number of occurrences for each motif that is found in the bacterial genome", this makes no sense to me (and may not to a lot others too)
3. A good post requesting assistance should in my humble opinion have the following information:
  • Clearly state the problem without any ambiguity. Break down your problem into the smallest part where you need help. Posting a question 100 lines long will yield no result. People will yawn and go back to doing their day job.
  • Show your attempt at solving the problem. This will help members focus on the exact place where you need help; and not have to dig about and assume where you might be facing the issue.
  • One line about your OS, your shell, preferred scripting language..
