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

Under Cygwin and Linux everything after the path of the shebang gets parsed to the program as one argument.

It's possible to hack around this by using another awk script inside the shebang:

#!/usr/bin/gawk {system("/usr/bin/gawk --re-interval -f " FILENAME); exit}

This will execute {system("/usr/bin/gawk --re-interval -f " FILENAME); exit} in awk.
And this will execute /usr/bin/gawk --re-interval -f path/to/your/script.awk in your systems shell.
