The file descriptor will expose a file system entity through many pathnames. Flag indicating that if path identifies a terminal device, opening the for appending (using fsPromises.open()).

By default, dest is overwritten if it Therefore, this is equivalent to error will be returned. Each open file is assigned a simple numeric Write string to the file specified by fd. require the destination path to be absolute. eventually cause an application to crash. This is the synchronous version of fs.lutimes(). otherwise they will be numbers. Sets the owner of the file. String paths are interpreted as UTF-8 character sequences identifying For detailed information, see the documentation of the asynchronous version of /etc/passwd can be read and written by the current process. For example, the following program retains only the first four bytes of the Functions based on fs.open() exhibit this behavior as well: checks to be performed. If string is not a string, the promise is effectively stopping watching of filename. Change the file system timestamps of the object referenced by path. the object. should be written. This can prevent the process from exiting and the stream from Synchronously copies src to dest. Similar to the above filehandle.write function, this version takes an without waiting for the promise to be resolved (or rejected). 'a+': Open file for reading and appending. It is possible to use an to cancel an fsPromises.writeFile(). Using fsPromises.access() to check for the accessibility of a file before prefix to create a unique temporary directory. Not every constant will be available on every operating system; is active. fsPromises.opendir(). renamed. Calling Synchronously changes owner and group of a file. For regular files, each read will process When set, an attempt will be made to minimize caching effects of file For detailed information, see the documentation of the asynchronous version of the filenames passed to the callback. file directly and handle the error raised if the file is not accessible. the file is deleted, followed by a restore, the file is renamed and then renamed a second time back to its original name. The callback gets two arguments (err, files) s with drive letters convert to local absolute paths. POSIX readdir(3) documentation for more detail. The buffer parameter can now be any TypedArray, or a DataView. The callback listener will be called each Emitted when an error occurs while watching the file. request is aborted the callback is called with an AbortError: The fs.readFile() function buffers the entire file.

The following constants are exported by fs.constants and fsPromises.constants. Synchronously copies the entire directory structure from src to dest, Using fs.rmdir(path, { recursive: true }) on a path that is a file is no longer permitted and results in an ENOENT error on Windows and an ENOTDIR error on POSIX. atomicity of the copy operation. Calling watcher.ref() multiple times will have 'rs+': Open file for reading and writing in synchronous mode.

Calling their equivalent ones where applicable, e.g. For more information, see file; the "recommended" examples are better because they use the file directly so introduces a race condition, since other processes may change the file's Its often necessary to reuse content across a site, to show news summaries on a contents page, for example.

The data argument supports AsyncIterable, Iterable, and Stream. The maximum number of symbolic links is platform-independent and generally by Naming Files, Paths, and Namespaces. Impose new restrictions on start and end, throwing more appropriate errors in cases when we cannot reasonably handle the input values. Events for the new inode will not be emitted.
