powerstat:tldr:02e87

The command powerstat -a ${interval} ${number_of_samples} is used to measure power consumption on a Linux system. Here is an explanation of the different components:

• powerstat: This is the command itself. It is a tool that analyzes power consumption on a Linux system.
• -a: This option stands for "all" and it instructs powerstat to measure power consumption on all available devices.
• ${interval}: This variable is used to specify the interval at which power consumption measurements will be taken. It represents the duration between consecutive samples. You need to replace ${interval} with an actual number representing the interval in seconds (e.g., 1, 2, 5).
• ${number_of_samples}: This variable is used to specify the number of samples to be taken. It represents the total number of power consumption measurements that will be recorded. You need to replace ${number_of_samples} with an actual number (e.g., 10, 100, 1000).

To use this command, you will need to open a terminal on a Linux system and run it with the desired interval and number of samples. The powerstat tool will then collect and report power consumption information for the specified duration.
