“bad interpreter” error message when trying to run awk executable

Question

I\'m trying to make an awk file executable. I\'ve written the script, and did chmod +x filename. Here is the code:

#!/bin/awk -v

\'TOPNUM = $1         


        

Answer 1

Actually this form is more preferrable:

#! /bin/awk -E 

Man told:

-E Similar to -f, however, this is option is the last one processed and should be used with #! scripts, particularly for CGI applications, to avoid passing in options or source code (!) on the command line from a URL. This option disables command-line variable assignments
