Join with gzipped files

Question

I want to use the command line join utility on two files. Unfortunately, they're gzipped. Because they're both gzipped, I can't use gzip -cd. Is there a slick way to do this without having to unzip them?

Answer 1

No, but bash (among other shells) can do process substitution.

join <(zcat foo.gz) <(zcat bar.gz)
