A easy commandline tool for finding processes that are creating a particular high load. I wanted to know what process creates the disk load. Start atop and press the key d and see the process that creates the high load. You see also the bytes written and read by the process. With the key shortcut CTRL+Cursor key you can see how high the data throughput is.
You have enough of typing every time ls -lah to see the state of copying files? Try watch ls -lah. Watch runs the given command in a configurable interval and displays the result. It can also highlight the diff between two outputs.
