Extract selected variables

[Muhammad Rahiz]

Dear all,

Two questions;

1. I have RegCM data in GrADS bin/ctl format. I want to extract selected
variables and save them to a new file. How do I do that?

2. How do I do (1) for all the output files that I have without having to
open and extract each individual file? Is there a script to help do that?

Thanks,
Muhammad
