>How do you deal with words like "---" in your text that look like the match separator of grep?

For this one you can use the "--" flag to signal that everything else should be treated as an argument.

    $ grep -rn -- -

yeah, I should have made that more clar: I was talking about the sed expression on p17. It looks for "--" in stdin. This could alsp be a word. I realize now that the first tr before removes all non a-zA-Z characters, so in this case it should not be an issue.

However intermixing text with separators is not trivial. There are reasons we use JSON/XML for exchanging structured data.
