How to check firmware version on Linux

Question: I would like to upgrade the firmware of my Linux computer. But first I want to check the firmware version. Is there any Linux command for that?

To find out the firmware version of a Linux computer, you can use a command line tool called dmidecode. This tool dumps the content of a computer's system BIOS table in a human-readable format. Displayed information includes various hardware properties such as firmware, motherboard, CPU, cache, memory controller, PCI slots, etc.

Run the following command, and look for firmware version under "BIOS information."

$ sudo dmidecode | more
