Help

By convention, most production-ready CLI tools have a "help" option that prints information about how to use the tool. It's usually accessed with one of the following:

--help (flag)
-h (flag)
help (first positional argument)

The "help" output is often easier to parse than a full man page. It's usually more of a quick start guide than a full manual.

For example:

grep --help

Assignment

In the shell on the right, print the help menu for grep.

Submit the shell checks.
