Filter InterProScan output for a specific function

Question

[Purger]

I am working with metagenomic data.

After running InterProScan (IPS), I want to get only the genes related to a function (for example lipid-active enzymes).

I know that there are some databases that only focus on a group of genes (like CAZy, VFDB,...) but the group I am wondering about doesn't have any database like that.

Can someone tell me the way to filter the IPS output, or is there any other annotation tool providing the filter option?

I imagine you can filter on things like E.C. numbers and domain names using bash, awk, R, or some other code.
