Help: low space error
 

I recently tried to install Marble, got bored and want to play marble with N900, it crashed during installation. Now, I cannot even run backup. It hanged. when running fast app man... it gave an error, you running 'low space'.... I remember there is a command under xterm/root, one can clear unfinished install app, I forget the command, somebody help? please, TIA,

I have not played with xterm for quite awhile, how do i look at space? free? dmsg? df? Have not done linus for ages... cant remember anything :(
