Examples
--------

Show disk I/O latency using the default values and the current directory, until interrupted

```
$ ioping .
4096 bytes from . (ext4 /dev/sda3): request=1 time=0.2 ms
4096 bytes from . (ext4 /dev/sda3): request=2 time=0.2 ms
4096 bytes from . (ext4 /dev/sda3): request=3 time=0.3 ms
4096 bytes from . (ext4 /dev/sda3): request=4 time=12.7 ms
4096 bytes from . (ext4 /dev/sda3): request=5 time=0.3 ms

--- . (ext4 /dev/sda3) ioping statistics ---

Measure disk seek rate (iops, avg)

```
$ ioping -R /dev/sda

--- /dev/sda (device 465.8 GiB) ioping statistics ---

```

Measure disk sequential speed (MiB/s)

```
$ ioping -RL /dev/sda

--- /dev/sda (device 465.8 GiB) ioping statistics ---
