Flag indicating that number of optional arguments is not limited.

◆ SHELL_OPT_ARG_MAX

#define SHELL_OPT_ARG_MAX (0xFD)

Flag indicating maximum number of optional arguments that can be validated.

◆ SHELL_OPT_ARG_RAW

#define SHELL_OPT_ARG_RAW (0xFE)

Flag indicates that optional arguments will be treated as one, unformatted argument.

By default, shell is parsing all arguments, treats all spaces as argument separators unless they are within quotation marks which are removed in that case. If command rely on unformatted argument then this flag shall be used in place of number of optional arguments in command definition to indicate that only mandatory arguments shall be parsed and remaining command string is passed as a raw string.
