Create a program in the "shell script" programming language to display a short message using "echo". Avoid using punctuation for now. Test it.
[solution]
Some punctuation is special to the shell and must be "quoted". Inside single-quotes, all of this special stuff is ignored.
Write an "echo" command which outputs the message
I like this * very * much (really)
[solution]
But single quotes can't be quoted with single quotes. What happens when you run the following file as a shell script? What is going on?
echo 'I don't know'
How about this? (It's different!)
echo 'I don't know much, but at least I ain't lost!'
[solution]
You can also use double-quotes in the shell. The semantics is slightly different, but not in a way which concerns us right now. Use double-quotes to write a shell script which outputs
I don't know
[solution]
