NAME

       isosize - output the length of an iso9660 filesystem

SYNOPSIS

       isosize [options] iso9660_image_file

DESCRIPTION

       This  command  outputs  the  length  of an iso9660 filesystem that is contained in the specified file.  This file may be a normal file or a
       block device (e.g. /dev/hdd or /dev/sr0).  In the absence of any options (and errors), it will output the size of the iso9660 filesystem in
       bytes.  This can now be a large number (>> 4 GB).

OPTIONS

       -x, --sectors
	      Show the block count and block size in human-readable form.  The output uses the term "sectors" for "blocks".

       -d, --divisor number
	      Only has an effect when -x is not given.	The value shown (if no errors) is the iso9660 file size in bytes divided by number.  So if
	      number is the block size then the shown value will be the block count.

       The size of the file (or block device) holding an iso9660 filesystem can be marginally larger than the actual size of the iso9660  filesys-
       tem.  One reason for this is that cd writers are allowed to add "run out" sectors at the end of an iso9660 image.

AVAILABILITY

       The  isosize  command  is  part	of the util-linux package and is available from Linux Kernel Archive <ftp://ftp.kernel.org/pub/linux/utils
       /util-linux/>.

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
