How to see this information from a command line?

iotop -o -a only measures the data accumulated since iotop was started.
-a, --accumulated
Show accumulated I/O instead of bandwidth. In this mode, iotop
shows the amount of I/O processes have done since iotop started.
gnome-system-monitor shows the amount of data since the process was started, even if gnome-system-monitor was started later.
