pipe two files as inputs of an script in linux command line

Question

I have 2 *.gz files. I want to cat them (zcat) and pipe them to a command as its inputs.

zcat file1.gz
zcat file2.gz

then pipe them in order as input

| script file1 file2  > 

Answer 1

If you're using bash or zsh, you can do this:

script <(zcat file1.gz) <(zcat file2.gz)

It's a bit more difficult otherwise, and I would probably use named pipes.
