Class CatOptionSets

java.lang.Object

org.unix4j.unix.cat.CatOptionSets

public final class CatOptionSets
extends Object

Options for the cat command with the the following options:

	-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 class serves as entry point to every possible set of cat options defined as an enum constant. With this explicit expansion of all possible option combinations, options can be passed to the command in a very compact form, such as:

 cat(Cat.Options.b, ...);
 cat(Cat.Options.b.n, ...);
 ...
 cat(Cat.Options.b.n.s, ...);
