On ubuntu you can show hardware information from the command line, there is a dedicated command for showing hardware information such as CPU, GPU, RAM, HDD, wifi, ethernet, etc.
To show hardware information from the command line we can use the 'lshw' command, this command always ask you to run with super user permission although it also works without it.
If you just run lshw without any parameter it will show everything, this can be difficult to read, so i suggest use special parameter to show on specific hardware you wish to see.
For example to see hardware information about CPU, simply run this command:
showing hardware information for graphic card (GPU)
showing hardware information for ram
showing hardware information for network device (wifi and ethernet/LAN)
showing hardware information for storage device
