How to use efetch to download specific gene from whole genome NCBI by linux terminal?

Question

[Ahmad]

I need download specific gene from whole genome (like gene length from 11200 bp to 11350 bp) on linux terminal.

You already have competent answers to your question, and this is not one of them. If I had to do the same for 500+ genes, I'd probably be looking for a similar solution as you have, because manual solutions would be so time-consuming. But for a single gene, I so would not trust the automated process because there are always things that can wrong. Unless this is for homework, how difficult is it to find a single gene on NCBI and manually excise the range of bases you need?

I have large number of genes, manually is difficult

You can use EntrezDirect for this as follows:

$ esearch -db gene -query '11200:11350[gene length] AND "homo sapiens"[organism]'

This returns 192 genes that satisfy this criteria. You can then pipe the output of the above command to other EntrezDirect tools depending on your downstream analysis.
