在目录上使用fs.watch似乎没有注意到添加的文件

Question

[当我在目录上使用fs.watch时：https://nodejs.org/docs/latest/api/fs.html#fs_fs_watch_filename_options_listener

在调用fs.watch之后，它没有注意到新文件添加到目录中。我在Linux上-是否需要打电话以使其注意到新添加/删除的文件？

返回的对象FSWatcher上的唯一事件是“更改”，“错误”和“关闭”-文件有“添加”或“删除”。

interface FSWatcher extends events.EventEmitter {
    close(): void;

    /**
     * events.EventEmitter
     *   1. change
     *   2. error
     */
    addListener(event: string, listener: (...args: any[]) => void): this;
    addListener(event: "change", listener: (eventType: string, filename: string | Buffer) => void): this;
    addListener(event: "error", listener: (error: Error) => void): this;
    addListener(event: "close", listener: () => void): this;

    on(event: string, listener: (...args: any[]) => void): this;
    on(event: "change", listener: (eventType: string, filename: string | Buffer) => void): this;
    on(event: "error", listener: (error: Error) => void): this;
    on(event: "close", listener: () => void): this;

    once(event: string, listener: (...args: any[]) => void): this;
    once(event: "change", listener: (eventType: string, filename: string | Buffer) => void): this;
    once(event: "error", listener: (error: Error) => void): this;
    once(event: "close", listener: () => void): this;

    prependListener(event: string, listener: (...args: any[]) => void): this;
    prependListener(event: "change", listener: (eventType: string, filename: string | Buffer) => void): this;
    prependListener(event: "error", listener: (error: Error) => void): this;
    prependListener(event: "close", listener: () => void): this;

    prependOnceListener(event: string, listener: (...args: any[]) => void): this;
    prependOnceListener(event: "change", listener: (eventType: string, filename: string | Buffer) => void): this;
    prependOnceListener(event: "error", listener: (error: Error) => void): this;
    prependOnceListener(event: "close", listener: () => void): this;
}

Nevermind-fs.watch确实看到了删除/添加/创建/未链接的文件。我的错误是仅将文件路径传递给fs.watch而不是传递目录。最好只传递目录。要在Linux上完成类似于fs.watch的操作，可以使用：

 inotifywait -m /path/one -m /path/two -m /path/three -e create \
           -e moved_to -e modify -e moved_from \
           -e move -e create -e delete -e delete_self
