Invoking a script, which has an awk shebang, with parameters (vars)

Question

I have an awk script that I have defined thus:

#!/usr/bin/env awk BEGIN { if (!len) len = 1; end = start + len } { for (i = start; i < end; i++) { print $1 } } 

I have saved it as columns and chmod +x'd it. I want invoke it so that start and end are defined as it traverses over a file. I was thinking this should work:

cat some_file | columns -v start=2 

But it doesn't. Help!

Try using:

#!/usr/bin/awk -f 

as an interpreter
