Subject: [9front] [PATCH] awk(1): quote argument for -v option
Date: Tue, 29 Nov 2022 13:10:26 +0100 [thread overview]
Message-ID: <Y4X2srVryGMhBXDR@x1.home> (raw)
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
