You might do this on your very personal computer. But you might not care to
pull this through on a production system with any number of users and an IT
department that might have to say something in this matter.

I came across the problem of embedded anonymous awk (and other) scripts in
shell scripts a long time ago. I used two methods, depending on the quality
of the embedded script. First one is to store the script on a file, along
with the shell script. Second is to embed, but write it to a temporary file
(of course, adding the process number to the name in the global temporary
file space) before you call it; delete it after the call.
