lsblk:tldr:3e041

The command "lsblk --output ${NAME},${SERIAL},${MODEL},${TRAN},${TYPE},${SIZE},${FSTYPE},${MOUNTPOINT}" is used to list information about block devices (such as hard drives, USB drives, etc.) in a Linux system.

Here's an explanation of the different parameters used in this command:

• "lsblk" is the command itself, used to list block devices.
• "--output" is an option that specifies the format of the output.
• "${NAME}" is a placeholder for the name of the device.
• "${SERIAL}" is a placeholder for the serial number of the device.
• "${MODEL}" is a placeholder for the model or make of the device.
• "${TRAN}" is a placeholder for the transport type of the device (e.g., sata, usb, etc.).
• "${TYPE}" is a placeholder for the type of device (e.g., disk, part, loop, etc.).
• "${SIZE}" is a placeholder for the size of the device.
• "${FSTYPE}" is a placeholder for the file system type present on the device.
• "${MOUNTPOINT}" is a placeholder for the mount point of the device (if it is currently mounted).

By running this command, you will get a table-like output with columns displaying the specified information for each block device detected in the system. The actual values will be displayed in place of the placeholders.
