       mkfs.minix - make a Minix filesystem


       mkfs.minix [options] device [size-in-blocks]


       mkfs.minix creates a Linux MINIX filesystem on a device (usually a disk partition).

       The device is usually of the following form:

           /dev/hda[1-8] (IDE disk 1)
           /dev/hdb[1-8] (IDE disk 2)
           /dev/sda[1-8] (SCSI disk 1)
           /dev/sdb[1-8] (SCSI disk 2)

       The device may be a block device or an image file of one, but this is not enforced. Expect
       not much fun on a character device :-).

       The size-in-blocks parameter is the desired size of the file system, in blocks. It is
       present only for backwards compatibility. If omitted the size will be determined
       automatically. Only block counts strictly greater than 10 and strictly less than 65536 are


       -c, --check
           Check the device for bad blocks before creating the filesystem. If any are found, the
           count is printed.

       -n, --namelength length
           Specify the maximum length of filenames. Currently, the only allowable values are 14
           and 30 for file system versions 1 and 2. Version 3 allows only value 60. The default
           is 30.

           Use exclusive BSD lock for device or file it operates. The optional argument mode can
           be yes, no (or 1 and 0) or nonblock. If the mode argument is omitted, it defaults to
           yes. This option overwrites environment variable $LOCK_BLOCK_DEVICE. The default is
           not to use any lock at all, but it’s recommended to avoid collisions with
           systemd-udevd(8) or other tools.

       -i, --inodes number
           Specify the number of inodes for the filesystem.

       -l, --badblocks filename
           Read the list of bad blocks from filename. The file has one bad-block number per line.
           The count of bad blocks read is printed.

           Make a Minix version 1 filesystem. This is the default.

       -2, -v
           Make a Minix version 2 filesystem.

           Make a Minix version 3 filesystem.

       -h, --help
           Display help text and exit.

       -V, --version
           Print version and exit. The long option cannot be combined with other options.


           use exclusive BSD lock. The mode is "1" or "0". See --lock for more details.


       The exit status returned by mkfs.minix is one of the following:

           No errors

           Operational error

           Usage or syntax error


       fsck(8), mkfs(8), reboot(8)
