Is this a homework assignment? Homework must be posted in the
Homework & Coursework Questions forum and must include a completely filled out
homework template.
If this is not homework, please explain what real-life problem this request is intended to solve. And, note that there is a big difference between number of "lines" in a file and a number of
[MESSAGE BEGIN] to
[MESSAGE END] blocks of text. It isn't at all clear whether you are talking about "lines" or "blocks".
And, no...
sed is not the tool to use for this job. (At least not for the complete job. It could be used for one or two parts of the job, but there are better tools for grabbing a number out of one file and processing another file based on that number.)
