How to assign ortholog name to K numbers

Question

[kcbaby9394]

Hello, I am working on a KEGG analysis and I am wondering if there is a way to get a list of KEGG ortholog IDs (i.e. name that corresponds to the K number). Currently, I have to copy the K number and then search it in the KEGG genes database to get the name of the ortholog which is time consuming. What I would like to do is get all of the IDs for my K numbers and put them into my results file so that I do not have to look up the ortholog ID in the KEGG genes database for each K number.

Has anyone been able to do something similar or have any ideas on how to go about doing this? Any input is appreciated, thanks!

There is this file:

If you download it and unpack, it has the following information (only the first 5 lines):
