The command "sudo nvme smart-log ${device}" is used to retrieve the Self-Monitoring, Analysis, and Reporting Technology (SMART) log data of an NVMe (Non-Volatile Memory Express) device.

Here's a breakdown of the different components within the command:

• "sudo" is a command used in Unix-like operating systems, such as Linux, to execute a command with superuser privileges. It is often used when administrative privileges are required to perform the operation.

• "nvme" is a command-line utility in Linux used to manage NVMe devices. NVMe is a protocol designed for accessing solid-state drives (SSDs) through a high-speed PCIe bus.

• "smart-log" is a specific nvme command that fetches the SMART log, which contains information about the health, temperature, and other vital attributes of an NVMe device.

• "${device}" is a placeholder or variable for the actual device name that you need to specify when using the command. The device name should be provided without the dollar sign.

To use this command, you need to know the device name of the NVMe drive you want to check. Replace "${device}" with the appropriate device name.
