Command line system information

If you’re not sure which components are installed in your server/pc, you can use inxi which is a command line system information script. It will show you the system hardware, CPU, drivers, Xorg, Desktop, Kernel, GCC version(s), Processes, RAM usage, and a wide variety of other useful information.

For example:
