This is a note: Notes often give important information about a tool.

This is a caution
This will inform you of something that you be careful about (because it could be harmful to your system).
This is a warning
This will inform you of something that you shouldn't do (because it probably will break something within your system).

Note: Note that some tools do not accept options.
Also note that most commands, even when not explicitly stated, will work with standard wildcards (or globbing patterns) such as *, [A-Z] and various other standard wildcards. Refer to the Section called Standard Wildcards (globbing patterns) in Chapter 20 for further information.
