The command "sudo blkid" is used to list all available block devices along with their corresponding unique identifiers (UUID), file system types, and other attributes.
Here is a breakdown of the command:
-
"sudo" is a command used in Unix-like operating systems to run commands with administrative or root privileges. It allows the user to execute the "blkid" command with elevated permissions.
-
"blkid" is a command-line utility that is used to retrieve information about block devices, which are typically storage devices such as hard drives, solid-state drives, or partitions. It queries the system to gather information about each block device and displays it in a structured format.
When you run the "sudo blkid" command, it will scan all block devices connected to your system and provide metadata about them. The output may include information like the device's UUID (a unique identifier assigned to the filesystem), the file system type (such as ext4, NTFS, FAT32), and other attributes like the label, size, and flags associated with the device.
