Enum FindOption

java.lang.Object

java.lang.Enum<FindOption>

org.unix4j.unix.find.FindOption

All Implemented Interfaces:

Serializable, Comparable<FindOption>, Iterable<FindOption>, Option, OptionSet<FindOption>, FindOptions

public enum FindOption
extends Enum<FindOption>
implements Option, FindOptions

Options for the find command.

For most applications, it may be more convenient to use Find.Options instead of the option constants defined here.

	-d		--typeDirectory		Consider only directories
	-f		--typeFile		Consider only regular files
	-l		--typeSymlink		Consider only symbolic links
	-x		--typeOther		Consider only files that are neither of directory (d), regular file (f) or symlink (l).
	-r		--regex		Use full regular expression syntax for the patterns specified by the name operand (This option is ignored if no name operand is specified).
	-i		--ignoreCase		Use case insensitive matching when applying the file name pattern specified by the name operand (This option is ignored if no name operand is specified).
	-n		--timeNewer		Consider only files that have been created, modified or accessed after or at the time specified by the time operand (the default) (This option is ignored if no time operand is specified).
	-o		--timeOlder		Consider only files that have been created, modified or accessed before or at the time specified by the time operand (This option is ignored if no time operand is specified).
	-c		--timeCreate		The time operand refers to the creation time of the file (This option is ignored if no time operand is specified).
	-a		--timeAccess		The time operand refers to the last access time of the file (This option is ignored if no time operand is specified).
	-m		--timeModified		The time operand refers to the last modification time of the file (the default) (This option is ignored if no time operand is specified).
	-z		--print0		Print the full file name on the standard output, followed by a null character (instead of the newline character used by default). This allows file names that contain newlines or other types of white space to be correctly interpreted by programs that process the find output. This option corresponds to the --delimiter0 option of xargs.
