Native file system watcher for Linux

for using with Jetbrains product like pycharm and idea :

The current limit can be verified by executing:

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

or

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf

… and issuing this command to apply the change:

sudo sysctl -p

Check if there is a file in /etc/sysctl.d with your parameter. These files override the /etc/sysctl.conf file
