mkfs.minix
MKFS.MINIX(8) System Administration MKFS.MINIX(8)
NAME
mkfs.minix - make a Minix filesystem
SYNOPSIS
mkfs.minix [-c|-l filename] [-n namelength] [-i inodecount] [-v] 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 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 the device for bad blocks before creating the filesystem. If any are found, the count is printed.
-n namelength
Specify the maximum length of filenames. Currently, the only allowable values are 14 and 30. The default is 30. Note that kernels
older than 0.99p7 only accept namelength 14.
-i inodecount
Specify the number of inodes for the filesystem.
-l 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.
-2, -v Make a Minix version 2 filesystem.
-3 Make a Minix version 3 filesystem.
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
mkfs(8), fsck(8), reboot(8)
AVAILABILITY
The mkfs.minix command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
