System messages
Warning messages
A warning message alerts you to a possible problem and prompts you to respond before the system
continues a task. For example, before you format a hard drive, a message warns you that you may lose all
data on the hard drive. Warning messages usually interrupt the task and require you to respond by typing
y (yes) or n (no).
NOTE: Warning messages are generated by either the application or the operating system. For more
information, see the documentation that accompanied the operating system or application.
