How to use multiple arguments for awk with a shebang (i.e. #!)?

Question

I\'d like to execute an gawk script with --re-interval using a shebang. The \"naive\" approach of

#!/usr/bin/gawk --re-interval -f
... awk scri         


        

Answer 1

Just for fun: there is the following quite weird solution that reroutes stdin and the program through file descriptors 3 and 4. You could also create a temporary file for the script.

#!/bin/bash
exec 3>&0
exec <<-EOF 4>&0
BEGIN {print "HALLO"}
{print \$1}
EOF
gawk --re-interval -f <(cat 0>&4) 0>&3

One thing is annoying about this: the shell does variable expansion on the script, so you have to quote every $ (as done in the second line of the script) and probably more than that.
