Get NVMe Firmware Version

To obtain the firmware version of an NVMe drive on a Debian-based system, you can use the nvme command-line utility. If it is not already installed, you can install it using the apt package manager:

sqlCopy code
sudo apt-get update
sudo apt-get install nvme-cli

After the nvme-cli tool is installed, you can check the firmware version of the NVMe drive using the following command:

bashCopy code
sudo nvme id-ctrl /dev/nvme0 -H

This command will display a lot of information about your NVMe drive. The "FR" field represents the firmware revision.

Please note that you might need to replace /dev/nvme0 with the correct path to your NVMe device if it's different. You can list all NVMe devices using the following command:

bashCopy code
ls /dev/nvme*

The output of this command will show you all the NVMe devices on your system. The main device names should look something like /dev/nvme0, /dev/nvme1, and so on, and each partition on those devices will be listed as /dev/nvme0n1, /dev/nvme0n1p1, etc.

Remember, it's always a good idea to run these commands with care and make sure you are pointing to the correct device.
