Class LsOptionSets

java.lang.Object

org.unix4j.unix.ls.LsOptionSets

public final class LsOptionSets
extends Object

Options for the ls command with the the following options:

	-a		--allFiles		Lists all files in the given directory, including hidden files (those whose names start with \".\" in Unix). By default, these files are excluded from the list.
	-h		--humanReadable		Print sizes in human readable format. (e.g., 1K, 234M, 2G, etc.)
	-l		--longFormat		Long format, displaying file types, permissions, number of hard links, owner, group, size, date, and filename.
	-R		--recurseSubdirs		Recursively lists subdirectories encountered.
	-r		--reverseOrder		Reverses the order of the sort to get reverse collating sequence or oldest first.
	-t		--timeSorted		Sorts with the primary key being time modified (most recently modified first) and the secondary key being filename in the collating sequence.

This class serves as entry point to every possible set of ls 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:

 ls(Ls.Options.a, ...);
 ls(Ls.Options.a.h, ...);
 ...
 ls(Ls.Options.a.h.l.R.r.t, ...);
