Heavy IO command


Hi All,
Is there a command to check specific processes that's using the most IO/disk usage? I know sar and ps but I want more specific details on IO on individual processes.

Thanks.

Thanks for the replies, I chked the man pages of top and it only displays CPU, MEM, SWAP, and Virt MEM usage. I don't see anything out IO usage. Can someone please point me in the right direction?

iotop is just a python script - google for it.
If you don't have the taskstats support in your kernel, it will tell you and exit no harm done. If you don't have the kernel support, you are out of luck.
