You can scroll up and down to see additional processes using the up and down arrows on your keyboard. The larger portion of the display shows the processes, organized by PID by default. Uptime shows how long the system has been up in hours, minutes and seconds along with days if it’s been up more than a day (e.g., Uptime: 1 day, 20:18:15). The load averages show how heavily loaded the system has been over the last 1, 5 and 15 minutes. This portion of the display also shows load averages and uptime. It also shows how many processes are currently running (using the CPU). The upper right of the display shows you the number of tasks, threads ( thr) and kernel threads ( kthr). Clearly this system is not very busy since it doesn't have to swap process data out of memory. Notice in the screenshot above that memory is being significantly used, but swap isn’t being used at all. If you ask for help by pressing F1, you’ll see an explanation of the colors along with other information. The green bars represent user processes, while red bars represent kernel processes. The top left shows the number of CPUs/cores on the system and how busy they are.

Stretch out the window and you’ll be able to see more details on more processes.

The htop display should look something like this: Sandra Henry-Stocker
