Redirect to file, including current prompt line

How to include the redirected command itself to the output file redirection? For example

echo "hello!">output.txt

I want the content of output file like this:

echo "hello!">output.txt
hello!

You may want one of two things here.

  1. Using tee to get the result of the echo sent to the terminal as well as to the file:

    $ echo 'hello!' | tee output
hello!
$ cat output
hello!

  2. Using script to capture the whole terminal session:

    $ script
Script started, output file is typescript
$ echo 'hello!' >output
$ cat output
hello!
$ exit
Script done, output file is typescript

    $ cat typescript
Script started on Sat Nov 10 15:15:06 2018
$ echo 'hello!' >output
$ cat output
hello!
$ exit

Script done on Sat Nov 10 15:15:37 2018

If this is not what you are asking for, then please clarify your question.
