about fsnotifywait

fsnotifywait can be added as Linux Command. run apt install inotofy-tools.

This command can watch file changed by fanotify API. fanotify is added Linux Kernel 5.10.

Compare inotifywatch, fsnotifywait uses FAN( fanotify API not inotify).

fanotify API can watch arbitrarily chosen dir, and recursively too many file in it which inotify cannot watch.

fsnotifywait -q --format '#%w%f %e ::::' -m -r -S -e create,delete,move,modify /mnt/sample

fsnotifywait -q --timefmt '%F %T' --format '{"time":"%T","type":"%e"}:%w%f%0' -m -r -F -e create,delete,move,modify,moved_from,moved_to /opt/work/sample/

This command will output this.
