If I run a
free -m, I get this output:
Is there a command that I could use to clear the used memory? I have tried this:
echo 1 > /proc/sys/vm/drop_caches
It will ask for
sudo. But even after
sudo, it gives bad command error.
Here is the link where I got to know about drop_caches.
I am just looking for a way on how to clear the cache.
