macOS Terminal – How to See Disk I/O Utilization Per Process Without iotop or pidstat

I have the same question like this, but for macOS.

There is a GUI solution with Activity Monitor. Any command line alternative? I use latest macOS Sierra.

iotop is available in macOS/OS X itself.

iotop relies on dtrace though and you have to disable SIP in systems like El Capitan/Sierra to run dtrace.

Check man iotop for options and then execute iotop as root :

sudo iotop [-C] [-D|-o|-P] [-j|-Z] [-d device] [-f filename] [-m mount_point] [-t top] [interval [count]]

ps -axc -o comm

tell app "System Events" to name of application processes would list only processes launched from an application bundle.

Try using iotop in Terminal:

iotop -C 5 12

This would output 12 samples, each 5 seconds long. See this answer for more information.
