Interface HeadOptions

All Superinterfaces:

Iterable<HeadOption>, OptionSet<HeadOption>

All Known Implementing Classes:

HeadOption, HeadOptions.Default, HeadOptionSet_cq

public interface HeadOptions
extends OptionSet<HeadOption>

Interface implemented by all option sets for the head command. It is recommended to use Head.Options to specify a valid combination of options.

The options for the head command are:

	-c		--chars		The count argument is in units of characters instead of lines. Starts from 1 and includes line ending characters.
	-q		--suppressHeaders		Suppresses printing of headers when multiple files are being examined.

This interface serves as an alias for the extended interface to simplify the command signature methods by avoiding generic parameters.
