    root@h:~# iotop --help

    Usage: /usr/sbin/iotop [OPTIONS]

    DISK READ and DISK WRITE are the block I/O bandwidth used during the sampling
    period. SWAPIN and IO are the percentages of time the thread spent respectively
    while swapping in and waiting on I/O more generally. PRIO is the I/O priority at
    which the thread is running (set using the ionice command).

    Controls: left and right arrows to change the sorting column, r to invert the
    sorting order, o to toggle the --only option, p to toggle the --processes
    option, a to toggle the --accumulated option, i to change I/O priority, q to
    quit, any other key to force a refresh.

    Options:
    --version show program's version number and exit
    -h, --help show this help message and exit
    -o, --only only show processes or threads actually doing I/O
    -b, --batch non-interactive mode
    -n NUM, --iter=NUM number of iterations before ending [infinite]
    -d SEC, --delay=SEC delay between iterations [1 second]
    -p PID, --pid=PID processes/threads to monitor [all]
    -u USER, --user=USER users to monitor [all]
    -P, --processes only show processes, not all threads
    -a, --accumulated show accumulated I/O instead of bandwidth
    -k, --kilobytes use kilobytes instead of a human friendly unit
    -t, --time add a timestamp on each line (implies --batch)
    -q, --quiet suppress some lines of header (implies --batch)
