.SH "NAME"
mkfs.bfs \- make an SCO bfs filesystem
.SH "SYNOPSIS"
.sp
\fBmkfs.bfs\fP [options] \fIdevice\fP [\fIblock\-count\fP]
.SH "DESCRIPTION"
.sp
\fBmkfs.bfs\fP creates an SCO bfs filesystem on a block device (usually a disk partition or a file accessed via the loop device).
.sp
The \fIblock\-count\fP parameter is the desired size of the filesystem, in blocks. If nothing is specified, the entire partition will be used.
.SH "OPTIONS"
.sp
\fB\-N\fP, \fB\-\-inodes\fP \fInumber\fP
.RS 4
Specify the desired \fInumber\fP 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.
.RE
.sp
\fB\-V\fP, \fB\-\-vname\fP \fIlabel\fP
.RS 4
Specify the volume \fIlabel\fP. I have no idea if/where this is used.
.RE
.sp
\fB\-F\fP, \fB\-\-fname\fP \fIname\fP
.RS 4
Specify the filesystem \fIname\fP. I have no idea if/where this is used.
.RE
.sp
\fB\-\-lock\fP[\fB=\fP\fImode\fP]
.RS 4
Use an exclusive BSD lock for the device or file that is operated upon.
The optional argument \fImode\fP can be \fByes\fP (\fB1\fP), \fBno\fP (\fB0\fP), or \fBnonblock\fP.
If the \fImode\fP argument is omitted, it defaults to \fByes\fP.
This option overrides the environment variable \fB$LOCK_BLOCK_DEVICE\fP.
The default is to not use any lock at all, but using a lock is recommended
to avoid collisions with \fBsystemd\-udevd\fP(8) or other tools.
.RE
.sp
\fB\-v\fP, \fB\-\-verbose\fP
.RS 4
Explain what is being done.
.RE
.sp
\fB\-c\fP
.RS 4
This option is silently ignored.
.RE
.sp
\fB\-l\fP
.RS 4
This option is silently ignored.
.RE
.sp
\fB\-h\fP, \fB\-\-help\fP
.RS 4
Display help text and exit.
.RE
.sp
\fB\-V\fP, \fB\-\-version\fP
.RS 4
Display version and exit.
Option \fB\-V\fP only works as \fB\-\-version\fP when it is the only option.
.RE
.SH "EXIT STATUS"
.sp
The exit status returned by \fBmkfs.bfs\fP is 0 when all went well, and 1 when something went wrong.
.SH "SEE ALSO"
.sp

.SH "REPORTING BUGS"
.sp
For bug reports, use the \c
.URL "https://github.com/util\-linux/util\-linux/issues" "issue tracker" "."
.SH "AVAILABILITY"
.sp
The \fBmkfs.bfs\fP command is part of the util\-linux package which can be downloaded from \c
.URL "https://www.kernel.org/pub/linux/utils/util\-linux/" "Linux Kernel Archive" "."
