iotop: Show only processes or threads actually doing I/O.
$ sudo iotop --only
try on your machine
The command "sudo iotop --only" is used to monitor and display I/O (Input/Output) usage on a Linux system. Here's a breakdown of the different components:
- "sudo" is a command that allows a user to run another command with administrative privileges. It is commonly used in situations where elevated access is required to perform certain operations.
- "iotop" is a utility that provides real-time monitoring of disk I/O usage by processes. It shows the amount of data read from and written to the disk by each process. It is particularly useful for identifying processes that are causing high disk I/O activity and potentially affecting system performance.
- "--only" is an optional argument that limits the output of iotop to only show processes that are actively performing I/O operations. Without this argument, iotop will display all processes, regardless of their I/O activity.
So, when you run "sudo iotop --only", you will see a live view of the processes that are currently using the disk I/O on your system. This can help you identify resource-intensive applications and take necessary actions to manage or optimize your system's performance.

never run a command you are not sure if it is safe.
