The sudo iotop --accumulated command is used in Unix-like systems to monitor and display the input/output (I/O) usage of different processes and storage devices.

Here is a breakdown of the command:

• sudo: This is a command that allows users to execute a command with administrative or superuser privileges. It prompts the user to enter their password before running the command.
• iotop: This is the main command that is used to display information about I/O usage. It provides a dynamic and real-time overview of I/O activities of processes on the system.
• --accumulated: This is an optional flag that can be added to the iotop command. When used, it changes the display to show accumulated I/O instead of the default per-second statistics. This means that instead of showing the current I/O rates, it shows the total amount of I/O performed by each process or device since the program started.

In summary, sudo iotop --accumulated command allows you to monitor the accumulated I/O usage of processes and storage devices with superuser privileges.
