I want to see which genes in archloro.txt match both lines of ArabidopsisParalogue.txt. I tried grep -f but that would just find the genes in both files have in common and not 2 genes that are in the same line. Any ideas on how to do this?

head archloro.txt

I could not post ArabidopsisParalogue.txt due to formating but there are two columns of genes listed.
