There are many ways in which you can get help with commands. One way of getting help with a command is by using the “man” command which provides the manual page.
For example, if you want to know more about how to use the “cp” command, you can read its manual page by using the following command in the terminal:
# man cp
Another way is to use the “–help” command. This will give you a brief outline of the arguments that can used with the command.
For example, if want to find what all options or parameters can be used along with the command “mv” or remove command, you can use it by typing the following:
# mv –help
