mkfs.bfs - make an SCO bfs filesystem


mkfs.bfs [options] device [block-count]


mkfs.bfs creates an SCO bfs filesystem on a block device (usually a disk partition or a file accessed via the loop device).

The block-count parameter is the desired size of the filesystem, in blocks. If nothing is specified, the entire partition will be used.


-N, --inodes number

Specify the desired number of inodes (at most 512). If nothing is specified, some default number in the range 48-512 is picked depending on the size of the partition.

-V, --vname label

Specify the volume label. I have no idea if/where this is used.

-F, --fname name

Specify the filesystem name. I have no idea if/where this is used.


Use exclusive BSD lock for device or file it operates. The optional argument mode can be yes, no (or 1 and 0) or nonblock. If the mode argument is omitted, it defaults to yes. This option overwrites environment variable $LOCK_BLOCK_DEVICE. The default is not to use any lock at all, but it’s recommended to avoid collisions with systemd-udevd(8) or other tools.

-v, --verbose

Explain what is being done.


This option is silently ignored.


This option is silently ignored.

-h, --help

Display help text and exit.

-V, --version

Print version and exit. Option -V only works as --version when it is the only option.


The exit status returned by mkfs.bfs is 0 when all went well, and 1 when something went wrong.
