View NVMe smart data from CLI in Linux:

Therefore install the package:

sudo apt install nvme-cli

Their GitHub-Repository can be found here: github.com/linux-nvme/nvme-cli.

Then use smart-log to view SMART data:

sudo nvme smart-log /path/to/device

→ /path/to/device can be /dev/nvme0

The output the can look like this:
