OP needs to get *protein.faa.gz files since protein data is needed.

OP take a look at the help for ncbi-genome-download. Give the option --format protein-fasta to get what you want.

(or download the genome or CDS data and tranform it yourself)

I am running this command ncbi-genome-download -l complete,chromosome bacteria --genus "Acinetobacter baumannii" --format protein-fasta

but this gives me MD5SUMS file names like this. I need fasta sequnces.

should be included in *.faa

The MD5sums are always provided. They correspond to the files you need which should be present in a folder named GCF_000....

You command is also wrong. complete,chromosome is not one argument to the --assembly-level option. You should specify one or the other. Similarly, bacteria is also a positional argument and should come last in the command.

Make sure you read the documentation on the github page.

Try:

ncbi-genome-download -s refseq -l complete --genus "Acinetobacter baumannii" -v -F protein-fasta bacteria

 ncbi-genome-download -s genbank -l complete --genus "Acinetobacter baumannii" -v -F protein-fasta bacteria

I got:

$  ls /refseq/bacteria

GCF_000018445.1:
GCF_000018445.1_ASM1844v1_protein.faa.gz  MD5SUMS

GCF_000021145.1:
GCF_000021145.1_ASM2114v1_protein.faa.gz  MD5SUMS

GCF_000021245.2:
GCF_000021245.2_ASM2124v2_protein.faa.gz  MD5SUMS

GCF_000069245.1:
GCF_000069245.1_ASM6924v1_protein.faa.gz  MD5SUMS

GCF_000186665.3:
GCF_000186665.3_ASM18666v4_protein.faa.gz  MD5SUMS

GCF_000187205.2:
GCF_000187205.2_ASM18720v4_protein.faa.gz  MD5SUMS
...
...

You may still end up with some empty folders, so you'll need to pull out all the fasta files seperately after with something like find ./ -name "*.faa.gz"
