How do I use htop?

Now run the htop monitoring tool by executing the following command on the terminal.

Htop is having three sections mainly

1. Header, where we can see info like CPU, Memory, Swap and also shows tasks, load average, and Up-time.
2. List of processes sorted by CPU utilization.
3. Footer shows different options like help, setup, filtertreekill, nice, quit, etc.

Press F2 or S for setup menu > there are four columns i.e Setup, Left Column, Right Column, and Available Meters.

Here, you can configure the meters printed at the top of the window, set various display options, select among color patterns and choose which columns are printed in which order.

Type tree or t to display processes tree view.

You can refer to function keys displayed at the footer to use this nifty htop application to monitor Linux running processes. However, we advise using character keys or shortcut keys instead of function keys as they may have mapped with some other functions during secure connection.
