In the second command, the output is being redirected to a file named patch-test.txt. That's why you are not getting anything on the screen.

sleep 10 && cat /proc/sys/vm/vfs_cache_pressure >> patch-test.txt


The third command will show you the output.

leafpad patch-test.txt

If you get any error related to leafpad, try to check if it is installed on your n900, if not, install through fapman.

Hope it helps.
