Glances is a very nice system information script for Linux. This can show a lot of very useful information when run. Install this on Ubuntu very easily.
┌──[jason@11000000.10101000.00000001.00000010]─[~] └──╼ ╼ $ sudo apt install glances |
Then just execute the glances command and this will open.
The screenshot below shows what this looks like, a most useful application to have running on a spare monitor.
Type “man glances” to get information on such things as the keybinds used by this script.
