# File System - Watcher

## 1 - Linux

File system watcher requires inotify(7) facility. The sign of inotify availability in a system is a presence of /proc/sys/fs/inotify/ directory.

File system watcher is a single binary executable (fsnotifier) and can be downloaded directly from our Git repository.

cat /proc/sys/fs/inotify/max_user_watches

It can be raised by adding following line to the /etc/sysctl.conf file:

fs.inotify.max_user_watches = 524288

… and issuing this command to apply the change:

sudo sysctl -p
