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.

-v, --verbose

Explain what is being done.


This option is silently ignored.


This option is silently ignored.

-h, --help

-V, --version

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