This is intended as a high-level overview so we will keep it simple here. This serves to optimize how and when the computer performs the task. Processes can be run in many different ways and are prioritized using a variety of algorithms. An operating system relies on a number of processes running in the background to make other activities possible, such as using a web browser. System processes are also known as tasks. ![]() Tasks Tasks: 210 total, 2 running, 208 sleeping, 0 stopped, 0 zombie For example, a load of 1.0 would mean that 100% of your processing power is currently at work. These figures are readings over 1 minute, 5 minutes, and 15 minutes, in that respective order.įor our purposes load values can be understood as an estimate of the “stress” on your system’s processing power. Next we see three values for the load average. This refers to how long the computer has been running without interruption. Next to it you will see the system up time. The first piece of information is a timestamp, which is pretty self-explanatory. User Info, Uptime, and Load Averages top - 11:49:05 up 27 min, 1 user, load average: 1.13, 0.44, 0.28 Let’s take them line by line and explain what’s going on. The first four lines contain the overview data I mentioned before. Let’s break it into smaller pieces so that we have a more complete understanding. There is a lot of detailed information displayed in a condensed format. Below that, we have a table with specific processes with plenty of details. You’ll notice that while running there are essentially 2 sections with information.Īt the top of our terminal, we get our overview data including memory usage and cpu load. You can easily check CPU load, the number of current tasks, as well as viewing information about memory usage. There are also other key commands to make full use of it that I’ll discuss later. When you want to exit, type the letter q to quit. This simple command will bring you into the top application. In this article, I will explain teach you how to navigate top command with confidence. Using and understanding a program like top is an essential system administration skill. It reports data about current processes which is refreshed (by default) every 3 seconds. The top command offers a quick overview of system information.
