HOWTO: Clear filesystem memory cache

danbh

well, I tried it, nothing seems to have happened really, except now ubuntu is using less ram

I had to ask to get a command that could be run with sudo, so I'm posting it here for reference:
sudo echo 3 | sudo tee /proc/sys/vm/drop_caches

Cool tip. I had to shutdown X server for it to really be effective. For GNOME the GNOME display manager will need to be disabled. I'm using Gentoo and the boot system is different for Ubuntu (Ubuntu uses RC, i believe?) but the xdm daemon needs to be stopped:

Code:

sudo /etc/init.d/xdm stop

ctrl-alt-del.
