Interface UniqOptions

All Superinterfaces:

Iterable<UniqOption>, OptionSet<UniqOption>

All Known Implementing Classes:

UniqOption, UniqOptions.Default, UniqOptionSet_cdgu, UniqOptionSet_cg, UniqOptionSet_dg, UniqOptionSet_gu

public interface UniqOptions
extends OptionSet<UniqOption>

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

The options for the uniq command are:

	-c		--count		Precedes each output line with a count of the number of times the line occurred in the input.
	-d		--duplicatedOnly		Suppresses the writing of lines that are not repeated in the input.
	-u		--uniqueOnly		Suppresses the writing of lines that are repeated in the input.
	-g		--global		Suppresses repeated lines globally, that is, if lines are non-adjacent. This option guarantees unique output lines even if the input lines are not sorted.

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