FW: sed command grouping brace match problem

[Caldwell, David (Overwatch Systems)]

I saw no evidence that my email to bonzini@...<mailto:bonzini@...> had any effect, so now I'm trying the email address in the sed --version output.

Hi,

I'm using Cygwin with sed version 4.2.1.

I can't get command grouping to work with both the open & closing braces on the same line when one of the commands is "r filename":
sed '/pattern/ { N; N; r fileToInsert }'

Attached is a script that reproduces the problem.

That is by design. You have to use either

sed -e '/pattern/ { N; N; r fileToInsert' -e '}'

or a real newline, ie

sed -e '/pattern/ { N; N; r fileToInsert
}'

bonzini@... was (and is :)) on vacation and tries to read email as
sparingly as possible. :)  Thanks Davide for following up.
