Command-line commands, entered using a keyboard (in the terminal or a terminal emulator), are marked with the command prompt character $ or # in the current manual. The character indicates the privileges required for execution of the specified command. According to the standard convention for UNIX-based systems,
$—indicates that the command can be executed with user rights.
#—indicates that the command can be executed with superuser (usually root) privileges. To elevate the privileges, use su and sudo commands.
