53 is used to create a Linux second extended file system on a device (usually
57 is the special file corresponding to the device (e.g /dev/hdXX).
60 is the number of blocks on the device. If omitted,
62 automagically figures the file system size.
66 Specify the size of blocks in bytes.
69 Check the device for bad blocks before creating the file system, using a
73 Specify the size of fragments in bytes.
76 Specify the bytes/inode ratio.
78 creates an inode for every
80 bytes of space on the disk. This value defaults to 4096 bytes.
82 must be at least 1024.

98 Quiet execution. Useful if mke2fs is run in a script.
104 Force mke2fs to run, even if the specified device is not a
105 block special device.
108 Write superblock and group descriptors only. This is useful if all of
109 the superblock and backup superblocks are corrupted, and a last-ditch
110 recovery method is desired. It causes mke2fs to reinitialize the
111 superblock and group descriptors, while not touching the inode table
112 and the block and inode bitmaps. The
114 program should be run immediately after this option is used, and there
115 is no guarantee that any data will be salvageable.

122 accepts the -f option but currently ignores it because the second
123 extended file system does not support fragments yet.
125 There may be some other ones. Please, report them to the author.
