And since one cannot reliably and portably quote a string into a
regular expression in Shell, one has to use:
$ grep -F -- "$string" ...
to search for a user-supplied string in a Shell script.
(The `--' ``option'' prevents `"$string"' from being processed
as an option even if it begins with `-'; consider, e. g.: `$
grep -l *' vs. `$ grep -- -l *'.)
