There is no "-n" command by default in linux, though it can be an option to other commands. For example, in the make(1) command, it can be used to suppress the make program from actually doing the actions specified - it just prints out what it would have done.
Answer
[-n] may be what is called a "switch" typically passed to a Unix or Linux command. As mentioned above, it modifies the actions of another command. For example, in the sort(1) command, it instructs sort to sort numerically instead of alphabetically. The meaning of any given switch will typically vary from command to command so read each man page carefully before using a switch. [JMH]
