This is a simple script that removes the "buff/cache" from RAM every 30 minutes. There nothing different.
One line. One command. And everything is ready!
curl -fsSL https://raw.githubusercontent.com/medowic/simple-memory-cleaner/master/install.sh | sudo bash
You can change the memory cleanup time in /etc/clmem.conf (may be, there will be more settings...)
