NCBI will be phasing out their entrez tools this year, so testing out their new datasets tool as replacement.
So far it's been great. Essentially a more general purpose, officially NCBI backed version of the famous ncbi-genome-download package people are already familiar with.
A quick download of genome accession set is as simple as:
datasets download genome accession --inputfile tmp.acc
Which certainly beats my 31 line script calling on entrez
