It is useful to see the output produced, but we'd generally avoid putting this directly in a shell script, as it causes the script to no longer run, e.g.
% ./script-01.sh
Selma
./script-01.sh: line 9: Selma: command not foundIf you're going to include the output, I'd recommend doing so in a comment (i.e. putting a # before the output) so that the scripts can still run :)

It looks like something went slightly wrong in your copy+paste here?
But this raises an interesting workflow question - there are two ways you can go about making this kind of script - you can work in the terminal then copy+paste into the file, or work in the file and run the file each time you want to try something out. How do you feel about the two? What are the advantages/disadvantages of each way of working?

How did you end up with a newline in the middle of your command here? (Same for script-06 and script-07, script-10, and script-11)?
