This section gives a summary of command usage. It enables you to see how options can be given to the command. For example:
cp [-iprR] directory1 directory2
The first word or consecutive characters are the name of the command.
The characters enclosed in [square brackets] are optional. A '-' (hyphen) preceding a character indicates that this is an option that can be applied to the command.
Options grouped together after a single hyphen, like this, [-abcD] can be used in this format. If they are given separately, like this, [-n] [-r] [-Z] then they must be used in this format.
Arguments are represented by a name such as file, filename or directory.
