To get information on the options used by a Linux command, you can use the man command followed by the command name, like this: man [command]. This will display the manual page for the command, detailing its options and usage. Alternatively, you can often use the --help option with the command (e.g., [command] --help) to get a brief summary of options and usage.
The 'man' or the 'info' command have documentation about utilities and commands in the system.
