Is there a xterm command to clear out ram that may still be used by apps that you have shut down?

At times my n900 feels slugish. And I dont feel like rebooting everytime.

Thanks

I wanted to know this too

If an application is shut down the memory is freed, thats how more or less all systems work.

pkill command
kill the process you like with PID.

run "top" on your XTerminal and then use "kill <pid>" to kill a process of your choice. For some, you might need to have root access...

ah, so no super command to free up any memory thats being used up uselessly.

thanks for the rplkies guys. ill have to keep "kill" in mind and figure out what i need to kill.

why do you want to keep your memory free? its bit like buying a ferrari and keeping it in garage forever....

think of the memory as oil. if the oil is dirty or low (fragments of memory being used by programs you thought were closed) the car starts running bad and making funny noises(other programs you are running start to skip or freeze).

i enjoy my ferrari, i just want to keep it running well.

The OS cannot identify pages as being "used up uselessly" nor could any command. A page is in use until the process that is using it is terminated.

90% of the time sluggish behavior is less from memory usage and more from cpu/disk usage. I've found it tends to be the background daemons like the mail daemon, tracker, and the thumbnailer.

wakkamis: RAM (memory) on the N900 (or any Linux system) does not work the way you think. It really doesn't. There's no reason to worry about dirty RAM.
