Interface CatOptions

All Superinterfaces:

Iterable<CatOption>, OptionSet<CatOption>

All Known Implementing Classes:

CatOption, CatOptions.Default, CatOptionSet_bns, CatOptionSet_bs, CatOptionSet_ns

public interface CatOptions
extends OptionSet<CatOption>

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

The options for the cat command are:

	-b		--numberNonBlankLines		Number the non-blank output lines, starting at 1.
	-n		--numberLines		Number the output lines, starting at 1.
	-s		--squeezeEmptyLines		Squeeze multiple adjacent empty lines, causing the output to be single spaced.

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