This is the list of backends that can be listed with fsmon -L:

  • inotify (linux / android)
  • fanotify (linux > 2.6.36 / android with custom kernel)
  • devfsev (osx /dev/fsevents – requires root)
  • kqueue (xnu – requires root)
  • kdebug (bsd?, xnu – requires root)
  • fsevapi (osx filesystem monitor api)

Use

The tool retrieves file system events from a specific directory and shows them in colorful format or in JSON.

It is possible to filter the events happening from a specific program name or process id (PID).

Usage: ./fsmon [-jc] [-a sec] [-b dir] [-B name] [-p pid] [-P proc] [path]
 -a [sec]  stop monitoring after N seconds (alarm)
 -b [dir]  backup files to DIR folder (EXPERIMENTAL)
 -B [name] specify an alternative backend
 -c        follow children of -p PID
 -f        show only filename (no path)
 -h        show this help
 -j        output in JSON format
 -L        list all filemonitor backends
 -p [pid]  only show events from this pid
 -P [proc] events only from process name
 -v        show version
 [path]    only get events from this path
