tune2fs:tldr:d8e43

The command "tune2fs" is a utility in Linux used to modify the properties of an ext2, ext3, or ext4 file system.

Here is an explanation of the command you provided:

• "tune2fs": This is the command itself, used to interact with ext2, ext3, or ext4 file systems.
• "-L": This option is used to set a new label for the file system. The label is a name assigned to the file system, which can be used to identify it more easily.
• "${'MY_LABEL'}": This is an example of a placeholder for a label. The notation "${...}" is often used to represent a variable or a value to be substituted in the command. In this case, the label "MY_LABEL" is used as an example, and it should be replaced with an actual label you want to assign to the file system.
• "${-dev-sdXN}": This is another placeholder representing the device file for the file system. The device file should be specified in the format "/dev/sdXN", where "X" is a letter representing the storage device (e.g., "sda", "sdb") and "N" is the partition number (e.g., "1", "2"). Like the label placeholder, this should be replaced with the actual device file of the file system you want to modify.

Putting it all together, the command "tune2fs -L ${'MY_LABEL'} ${-dev-sdXN}" is used to change the label of a specified ext2, ext3, or ext4 file system. However, it would be better to replace the placeholders with actual values before running the command.
