I am not an awk expert. But from your problem statement, you have file 1 with some names. Then another file 2 with some data. The output swaps the data associated with >name1 and >name3. Can you show what would happen if there was say, some >name2 or some >name4 data there?

I don't find: "awk 'NR==FNR {a$1;next} $1 in a {print RS$0}' file1 RS=">" file2 > output" easy to understand.
