Genomics: Downloading genomic data from the NCBI Genbank database I'm taking a genomics course at school, and we have a final project due in a few weeks. 
Now, I can write bash scripts to sort and analyze the data, etc. However, I'm not quite sure how to actually get the data from the database. I was hoping to get some help there.

I'd like to get the assemblies of genomes for the species in the Borrelia genus. Is there any way that I can do this using commands like "wget", for example. I'm not even sure what URL I'd have to give the computer to go fetch these. Then once I give it the correct URL, how should I tell it what file in that directory to download?

I'd greatly appreciate some help on this issue.
For downloading data from commandline use the E-utilities of NCBI.
