Trigger service on file change

Create service file

nano /etc/systemd/system/lsws-restart.service

Content:

[Service]
Type=oneshot
ExecStart=/usr/bin/systemctl restart lsws.service

[Install]
WantedBy=multi-user.target

Create "path" service

nano /etc/systemd/system/lsws-restart.path

Content:

[Path]
PathChanged=/usr/local/lsws/vhosts/xxx/http/current/public/.htaccess

[Install]
WantedBy=multi-user.target

Enable "path" service

systemctl enable lsws-restart.path
systemctl start lsws-restart.path

And let the magic begin
