Inotify is an inode-based filesystem notification technology. It provides the possibility to monitor various events on files in filesystems. It is a very much great replacement of (obsolete) dnotify. Inotify brings a comfortable way how to manage files used in your applications.
Name
inotify - monitoring file system events
Description
The inotify API provides a mechanism for monitoring file system events. Inotify can be used to monitor individual files, or to monitor directories.When a directory is monitored, inotify will return events for the directory itself, and for files inside the directory.
The following system calls are used with this API: inotify_init(2) (or inotify_init1(2)), inotify_add_watch(2),inotify_rm_watch(2), read(2), and close(2).
inotify_init(2) creates an inotify instance and returns a file descriptor referring to the inotify instance. The more recent inotify_init1(2)is like inotify_init(2), but provides some extra functionality.
inotify_add_watch(2) manipulates the 'watch list' associated with an inotify instance. Each item ('watch') in the watch list specifies the pathnameof a file or directory, along with some set of events that the kernel should monitor for the file referred to by that pathname. inotify_add_watch(2)either creates a new watch item, or modifies an existing watch. Each watch has a unique 'watch descriptor', an integer returned by inotify_add_watch(2)when the watch is created.
inotify_rm_watch(2) removes an item from an inotify watch list.
When all file descriptors referring to an inotify instance have been closed, the underlying object and its resources are freed for reuse by the kernel; allassociated watches are automatically freed.
To determine what events have occurred, an application read(2)s from the inotify file descriptor. If no events have so far occurred, then, assuming ablocking file descriptor, read(2) will block until at least one event occurs (unless interrupted by a signal, in which case the call fails with theerror EINTR; see signal(7)).
Each successful read(2) returns a buffer containing one or more of the following structures:
wd identifies the watch for which this event occurs. It is one of the watch descriptors returned by a previous call to inotify_add_watch(2).mask contains bits that describe the event that occurred (see below). Spinworks for mac.
cookie is a unique integer that connects related events. Currently this is only used for rename events, and allows the resulting pair ofIN_MOVED_FROM and IN_MOVED_TO events to be connected by the application. For all other event types, cookie is set to 0.
The name field is only present when an event is returned for a file inside a watched directory; it identifies the file pathname relative to thewatched directory. This pathname is null-terminated, and may include further null bytes to align subsequent reads to a suitable address boundary.
The len field counts all of the bytes in name, including the null bytes; the length of each inotify_event structure is thussizeof(struct inotify_event)+len.
The behavior when the buffer given to read(2) is too small to return information about the next event depends on the kernel version: in kernelsbefore 2.6.21, read(2) returns 0; since kernel 2.6.21, read(2) fails with the error EINVAL. Specifying a buffer of size
sizeof(struct inotify_event) + NAME_MAX + 1
will be sufficient to read at least one event.
inotify events
File was accessed (read) (*).
IN_ATTRIB
Metadata changed, e.g., permissions, timestamps, extended attributes, link count (since Linux 2.6.25), UID, GID, etc. (*).
IN_CLOSE_WRITE
File opened for writing was closed (*).
IN_CLOSE_NOWRITE
File not opened for writing was closed (*).
IN_CREATE
File/directory created in watched directory (*).
IN_DELETE
File/directory deleted from watched directory (*).
IN_DELETE_SELF
Watched file/directory was itself deleted.
IN_MODIFY
File was modified (*).
IN_MOVE_SELF
Watched file/directory was itself moved.
IN_MOVED_FROM
File moved out of watched directory (*).
IN_MOVED_TO
File moved into watched directory (*).
IN_OPEN
File was opened (*).
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 thereturned inotify_event structure identifies the name of the file within the directory.The IN_ALL_EVENTS macro is defined as a bit mask of all of the above events. This macro can be used as the mask argument when callinginotify_add_watch(2).
Two additional convenience macros are IN_MOVE, which equates to IN_MOVED_FROM|IN_MOVED_TO, and IN_CLOSE, which equates toIN_CLOSE_WRITE|IN_CLOSE_NOWRITE.
The following further bits can be specified in mask when calling inotify_add_watch(2):
Don't dereference pathname if it is a symbolic link.
- The following interfaces can be used to limit the amount of kernel memory consumed by inotify:
- /proc/sys/fs/inotify/max_queued_events
- The value in this file is used when an application calls inotify_init(2) to set an upper limit on the number of events that can be queued to thecorresponding inotify instance. Events in excess of this limit are dropped, but an IN_Q_OVERFLOW event is always generated.
- /proc/sys/fs/inotify/max_user_instances
- This specifies an upper limit on the number of inotify instances that can be created per real user ID.
- /proc/sys/fs/inotify/max_user_watches
- This specifies an upper limit on the number of watches that can be created per real user ID.
Versions
Inotify was merged into the 2.6.13 Linux kernel. The required library interfaces were added to glibc in version 2.4. (IN_DONT_FOLLOW,IN_MASK_ADD, and IN_ONLYDIR were only added in version 2.5.)
Conforming To
The inotify API is Linux-specific.
Notes
Inotify file descriptors can be monitored using select(2), poll(2), and epoll(7). Activation key macrepair. When an event is available, the file descriptorindicates as readable.

Since Linux 2.6.25, signal-driven I/O notification is available for inotify file descriptors; see the discussion of F_SETFL (for setting theO_ASYNC flag), F_SETOWN, and F_SETSIG in fcntl(2). The siginfo_t structure (described in sigaction(2)) that is passedto the signal handler has the following fields set: si_fd is set to the inotify file descriptor number; si_signo is set to the signal number;si_code is set to POLL_IN; and POLLIN is set in si_band.
If successive output inotify events produced on the inotify file descriptor are identical (same wd, mask, cookie, and name) thenthey are coalesced into a single event if the older event has not yet been read (but see BUGS).
The events returned by reading from an inotify file descriptor form an ordered queue. Thus, for example, it is guaranteed that when renaming from onedirectory to another, events will be produced in the correct order on the inotify file descriptor.
The FIONREAD ioctl(2) returns the number of bytes available to read from an inotify file descriptor.
Limitations and caveats
Inotify monitoring of directories is not recursive: to monitor subdirectories under a directory, additional watches must be created. This can take asignificant amount time for large directory trees.The inotify API provides no information about the user or process that triggered the inotify event. In particular, there is no easy way for a process thatis monitoring events via inotify to distinguish events that it triggers itself from those that are triggered by other processes.
Note that the event queue can overflow. In this case, events are lost. Robust applications should handle the possibility of lost events gracefully.
The inotify API identifies affected files by filename. However, by the time an application processes an inotify event, the filename may already have beendeleted or renamed.
If monitoring an entire directory subtree, and a new subdirectory is created in that tree, be aware that by the time you create a watch for the newsubdirectory, new files may already have been created in the subdirectory. Therefore, you may want to scan the contents of the subdirectory immediately afteradding the watch.
Bugs
In kernels before 2.6.16, the IN_ONESHOTmask flag does not work.
Before kernel 2.6.25, the kernel code that was intended to coalesce successive identical events (i.e., the two most recent events could potentially becoalesced if the older had not yet been read) instead checked if the most recent event could be coalesced with the oldest unread event.

Elixir Koans
Elixir koans is a fun, easy way to get started with the elixir programming language. It is a tourof the most important features and idiomatic usage of the language.
Installing Elixir
Elixir runs on the Erlang VM, so to get started with the koans you need to install both Erlang and Elixir. The official Elixir webpage has instructions for how to do this.
Installing Inotify
If you're on a Mac, you can skip this section.
To provide the best experience, koans are run automatically when you save a file. This is accomplished with a tool called
inotify
which needs to be installed separately if you're not using OSX. Linux users will need to install inotify-tools
(guides), and Windows users need inotify-win
(guides).Getting the koans
The next step is to get the source code of the koans so that you can run it. Assuming that you have git installed, it's as simple as:
With the source code pulled, you'll also need to fetch the dependencies for this project:
Running the koans
Now you're ready to run the koans! On your command line, type:
You should see that the first koan has failed in
lib/koans/01_equalities.ex
. Open that file, and change the first koan to make the assertion true. After successfully passing the koan, you should see the next failure.Repeat
Keep making changes to satisfy the assertions in the code. When you've finished the first file, the runner will automatically run the next file until there are no more koans.
