Create a Linux file system on a hard-disk partition or a diskette.
mkfs [-V] [-t] [options] device_name [blocks]
-V produces verbose output needed for testing.
-t fstype specifies the file system type (such as ext2).
-c checks the device for bad blocks before creating the file system.
-l filename reads the bad-block list from specified file.
The mkfs command creates a Linux file system on a specified device. The device is typically a hard-disk partition or a diskette (that has been formatted with fdformat).
