Raspberry Pi is a little useful computer for learning programming and building projects. It comes with Debian Linux based modified operating system called Raspbian. It is the most widely installed OS on RPi. In a recent update, the Raspberry Pi OS installed a Microsoft apt repository on all machines running Raspberry Pi OS without the person’s or admin’s knowledge.

S-tui is a free and open source terminal UI for monitoring your computer. s-tui allows to monitor CPU temperature, frequency, power and utilization in a graphical way from the terminal. It is written in Python and need root permission to use the s-tui. It is useful for:

  1. Watch your CPU temperature/utilization/frequency/power
  2. See performance dips caused by thermal throttling
  3. No need to use X-server. Perfect for headless usage including Raspberry PI

Let us see how to install and use s-tui on a Linux based system.
