mkfs - build a Linux filesystem SYNOPSIS
mkfs [options] [-t type] [fs-options] device [size] DESCRIPTION
mkfs is used to build a Linux filesystem on a device, usually a hard disk partition. The device argument is either the device name (e.g. /dev/hda1, /dev/sdb2), or a regular file that shall contain the filesystem. The size argument is the number of blocks to be used for the filesystem. The exit code returned by mkfs is 0 on success and 1 on failure. In actuality, mkfs is simply a front-end for the various filesystem builders (mkfs.fstype) available under Linux. The filesystem-specific builder is searched for in a number of directories, like perhaps /sbin, /sbin/fs, /sbin/fs.d, /etc/fs, /etc (the precise list is defined at compile time but at least contains /sbin and /sbin/fs), and finally in the directories listed in the PATH environment variable. Please see the filesystem-specific builder manual pages for further details. OPTIONS
-t, --type type Specify the type of filesystem to be built. If not specified, the default filesystem type (currently ext2) is used. fs-options Filesystem-specific options to be passed to the real filesystem builder. Although not guaranteed, the following options are sup- ported by most filesystem builders. -V, --verbose Produce verbose output, including all filesystem-specific commands that are executed. Specifying this option more than once inhibits execution of any filesystem-specific commands. This is really only useful for testing. -V, --version Display version information and exit. (Option -V will display version information only when it is the only parameter, otherwise it will work as --verbose.) -h, --help Display help and exit. BUGS
All generic options must precede and not be combined with filesystem-specific options. Some filesystem-specific programs do not support the -V (verbose) option, nor return meaningful exit codes. Also, some filesystem-specific programs do not automatically detect the device size and require the size parameter to be specified. AUTHORS

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 util-linux June 2015 MKFS.MINIX(8)
