mkfs.minix

MKFS.MINIX(8)						       System Administration						     MKFS.MINIX(8)

NAME

       mkfs.minix - make a Minix filesystem

SYNOPSIS

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

DESCRIPTION

       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 a 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 omit-
       ted the size will be determined automatically.  Only block counts strictly greater than 10 and strictly less than 65536 are allowed.

OPTIONS

       -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.  Ver-
	      sion 3 allows only value 60.  The default is 30.

       -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.

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

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

       -3     Make a Minix version 3 filesystem.

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

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

EXIT CODES

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

       0      No errors

       8      Operational error

       16     Usage or syntax error

SEE ALSO

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

AVAILABILITY

       The mkfs.minix command is part of the util-linux package and is available from https://www.kernel.org/pub/linux/utils/util-linux/.
