   5 .SH NAME
   6 mkfs \- make a Linux MINIX filesystem
   7 .SH SYNOPSIS
   8 .BR "mkfs [ \-c ] [ \-n"
   9 namelength
  10 .B ] [ \-i
  11 inodecount
  12 .B ]
  13 device size-in-blocks
  14 .br
  15 .B "mkfs [ \-l"
  16 filename
  17 .B ]
  18 device size-in-blocks
  19 .SH DESCRIPTION
  20 .B mkfs
  21 creates a Linux MINIX file-system on a device (usually a disk partition).
  22
  23 The
  24 .I device
  25 is usually of the following form:
  26
  27 .nf
  28 .RS
  29 /dev/hda[1-8]
  30 /dev/hdb[1-8]
  31 /dev/sda[1-8]
  32 /dev/sdb[1-8]
  33 .RE
  34 .fi
  35
  36 The
  37 .I size-in-blocks
  38 parameter is the desired size of the file system, in blocks.  This
  39 information can be determined from the
  40 .BR fdisk (8)
  41 program.  Only block counts strictly greater than 10 and strictly less than
  42 65536 are allowed.
  43 .SH OPTIONS
  44 .TP
  45 .B \-c
  46 Check the device for bad blocks before creating the file system.  If any
  47 are found, the count is printed.
  48 .TP
  49 .BI \-n " namelength"
  50 Specify the maximum length of filenames.  No space is allowed between the
  51 .B \-n
  52 and the
  53 .IR namelength.  Currently, the only allowable
  54 values are 14 and 30.
  55 .B 30 is the default.
  56 .TP
  57 .BI \-i " inodecount"
  58 Specify the number of inodes for the filesystem.
  59 .TP
  60 .BI \-l " filename"
  61 Read the bad blocks list from
  62 .IR filename .
  63 The file has one bad block number per line.  The count of bad blocks read
  64 is printed.
  65 .SH "EXIT CODES"
  66 The exit code returned by
  67 .B mkfs.minix
  68 is one of the following:
  69 .IP 0
  70 No errors
  71 .IP 8
  72 Operational error
  73 .IP 16
  74 Usage or syntax error
