![]() ![]() It can gather information from hard disk, monitor, keyboard, mouse, network card and etc. This command can extract information form hardware. It is used to monitor the system’s condition and health. Hardware information or in short, the hwinfo command is a very professional command to identify the filesystem UUID of Linux. Identifying FileSystem UUID in Linux By hwinfo Command You can also check the dumpe2fs version of your Linux machine. Let, if we want to run the dumpe2fs command on the location of sda1 in our Linux filesystem, all we need is to type the following command in the terminal. The dumpe2fs command can determine where the file is mounted, the UUID of the filesystem, filesystem magic number, filesystem flags, error behavior, Filesystem OS type, free blocks, Flex block group size, and many more things. If you lose your superblock on a filesystem, you lose the access to that filesystem. The dumpe2fs command is used to identify the blocksize, superblock information of a file system. ![]() Identifying Disk Partition UUID By dumpe2fs Command $ udevadm trigger -verbose -dry-run -type=devices -subsystem-match=scsi_disk We can also use trigger action under udevadm command. The output will be like the picture provided below. $ udevadm monitorĪnd the monitor will print the received events for: UDEV - the event which udev sends out after rule processingĪfter this stage, if we insert any removable device, it will print the disk status in the terminal. Let, we want to check the removable file status on the terminal using udevadm, we can type the following command in the terminal. The udevadm command can gather file info from the database, trigger any action under administrative user, control the udev daemon, monitor the Kernel, and test an event. ![]() Runtime contents are associated with the processes undergoing inside the device. Userspace device manager administrator or, in short, udevadm is a command used in Linux to identify the runtime and kernel events of a file. Determining Disk Partition UUID in Linux By udevadm Command The lsblk command can show the name, device type, major-minor device numbers, removable device, mount point, size of the device, etc. Identifying FileSystem UUID in Linux By lsblk Commandīlockwise List information, lsblk command is used to see the detailed information and the UUID of the filesystem in Linux. And in the output, we will find the UUID, partition ID, and the type of the driver. For that, we need to type the following command in the terminal. Let, we want to find the UUID of the /dev/sda1 location. The blkid command can identify the UUID and details information of the Linux filesystem. Identifying FileSystem UUID By blkid Commandįor determining the block device attributes of the Linux filesystem, we can use the block identification (blkid)command in the terminal. If you find any error like, permission denied while trying to open /dev/sda1 you can try the second command that includes sudo (superuser do). For that, we need to type the following command in the terminal using the tune2fs command. Let, we want to see the filesystem UUID properties of my dev/sda1 location. If you want to see the details usages of tune2fs, just simply type tune2fs in the Terminal, it will show the lists that can be done by tune2fs. The tune2fs is a powerful command that can also determine the current file settings of your Linux filesystem. If you need to change the variables or parameters of those files, you can use the tune2fs command. You may know that in Windows, files are mostly created in NTFS or Fat32, but in Linux, files are generated in ext2, ext3, or ext4 filesystems. ![]() The tune2fs is a command in Linux that can be used to adjust the framework of tunable files. Identifying FileSystem UUID in Linux By tune2fs Command The formation of UUID contains a timestamp variation, the encoded MAC address, and some randomly generated numbers. ![]()
