Module: InotifyEvents

Defined in:: lib/inotify.rb

Overview

Constants for each inotify event found in /usr/include/sys/inotify.h, descriptions from inotify man page (7), (note: When monitoring a directory, the events marked with an asterisk (*) above can occur for files in the directory, in which case the name field in the returned inotify_event structure identifies the name of the file within the directory.)

Constant Summary collapse

IN_ACCESS = File was accessed (read) (*).

0x00000001

IN_MODIFY = File was modified (*).

0x00000002

IN_ATTRIB = Metadata changed, e.g., permissions, timestamps, extended attributes, link count (since Linux 2.6.25), UID, GID, etc. (*).

0x00000004

IN_CLOSE_WRITE = File opened for writing was closed (*).

0x00000008

IN_CLOSE_NOWRITE = File not opened for writing was closed (*).

0x00000010

IN_CLOSE = File was closed (*).

(IN_CLOSE_WRITE | IN_CLOSE_NOWRITE)

IN_OPEN = File was opened (*).

0x00000020

IN_MOVED_FROM = Generated for the directory containing the old filename when a file is renamed (*).

0x00000040

IN_MOVED_TO = Generated for the directory containing the new filename when a file is renamed (*).

0x00000080

IN_MOVE = Generated when a file is moved (*).

(IN_MOVED_FROM | IN_MOVED_TO)

IN_CREATE = File/directory created in watched directory (*).

0x00000100

IN_DELETE = File/directory deleted from watched directory (*).

0x00000200

IN_DELETE_SELF = Watched file/directory was itself deleted.

0x00000400

IN_MOVE_SELF = Watched file/directory was itself moved.

0x00000800

IN_UNMOUNT = Filesystem containing watched object was unmounted.

0x00002000

IN_Q_OVERFLOW = Event queue overfloved.

0x00004000

IN_IGNORED = Watch was removed explicitly (inotify_rm_watch(2)) or automatically (file was deleted, or filesystem was unmounted).

0x00008000

IN_ONLYDIR = Only watch pathname if it is a directory.

0x01000000

IN_DONT_FOLLOW = Don’t dereference pathname if it is a symbolic link.

0x02000000

IN_EXCL_UNLINK = By default, when watching events on the children of a directory, events are generated for children even after they have been unlinked from the directory. This can result in large numbers of uninteresting events for some applications (e.g., if watching /tmp, in which many applications create temporary files whose names are immediately unlinked). Specifying IN_EXCL_UNLINK changes the default behavior, so that events are not generated for children after they have been unlinked from the watched directory.

0x04000000

IN_MASK_ADD = Add (OR) events to watch mask for this pathname if it already exists (instead of replacing mask).

0x20000000

IN_ISDIR = Subject of this event is a directory.

0x40000000

IN_ONESHOT = Monitor pathname for one event, then remove from watch list.

0x80000000

IN_ALL_EVENTS = Set all events.
