Subject: [9front] [PATCH] awk(1): quote argument for -v option
Reply-To: 9front@9front.org
Precedence: bulk

Dear all,

Running awk from rc, I found that I need to quote the arguments to awk's
-v option, as in:

	awk -v 'myvar=asdf' 'BEGIN{print myvar}'

However, the awk man page specifies this without quotes as "awk -v
myvar=asdf".  I now realize that it will not work without quotes because
rc tries to interpret the assignment operator.

Is this just a beginner mistake, being used to unix behavior, or worth
documenting as in the patch below?

Thanks, Anders
