I would grep for the gene name like grep 'Genename' *.rpkmfiles.

Edit: Yes, use -w as mentioned below to avoid partial matches of gene names.

You might want to add a -w to make sure not to get matches to other gene names containing your search pattern. Something like gene "ABC" might otherwise also match gene "ABCD" or gene "AABC2"..
