  22. Is a monitor——windows(ReadDirectoryChangesW)，macos(FSEvents) and linux(fanotifyandinotify) Simple examples of directory monitoring;
    1. fanotifyUsed inglobalMode, infanotify_markJoinFAN_MARK_FILESYSTEM(needCAP_SYS_ADMINability, that is, root permissions)flag, All events on the specified file system can be monitored, and then the required events can be filtered according to the specified monitored folder directory. This function is moreinotifyMore powerful;
      1. Get the upper path where the event file is located, usingopen_by_handle_atThis method will appear under ordinary usersOperation not permittedError, also requiredCAP_SYS_ADMINAbility, that is, root permissions;
      2. It is recommended to use root permissions to run. If you must run it under normal users, it is recommended to use it.inotifyInsteadfanotify, open a monitoring file descriptor (fd) cannot be achievedsubtreemonitor;
