.Sh NAME
.Nm fdwrite
.Nd format and write floppy disks
.Sh SYNOPSIS
.Nm
.Op Fl v
.Op Fl y
.Op Fl f Ar inputfile
.Op Fl d Ar device
.Sh DESCRIPTION
The
.Nm
utility formats and writes one and more floppy disks.
Any floppy disk device capable of formatting can be used.
.Pp
The
.Nm
utility will ask the user
(on
.Pa /dev/tty )
to insert a new floppy and press return.
The device will then be opened, and queried for its parameters,
then each track will be formatted, written with data from the
.Ar inputfile ,
read back and compared.
When the floppy disk is filled, the process is repeated, with the next disk.
This continues until the program is interrupted or EOF is encountered on the
.Ar inputfile .
.Pp
The options are as follows:
.Bl -tag -width 10n -offset indent
.It Fl v
Toggle verbosity on stdout.
Default is ``on''.
After
.Ar device
is opened first time the format will be printed.
During operation progress will be reported with the number of tracks
remaining on the current floppy disk, and the letters I, Z, F, W,
R and C, which indicates completion of Input, Zero-fill, Format
Write, Read and Compare of current track respectively.
.It Fl y
Don't ask for presence of a floppy disk in the drive.
This non-interactive flag
is useful for shell scripts.
.It Fl f Ar inputfile
Input file to read.  If none is given, stdin is assumed.
.It Fl d Ar device
The name of the floppy device to write to.  Default is
.Pa /dev/fd0 .
.El
.Pp
The
.Nm
utility actually closes the
.Ar device
while it waits for the user to press return,
it is thus quite possible to use the drive for other purposes at this
time and later resume writing with the next floppy.
.Pp
The parameters returned from
.Ar device
are used for formatting.
If custom formatting is needed, please use
.Xr fdformat 1
instead.
.Sh EXAMPLES
The
.Nm
utility
was planned as a tool to make life easier when writing a set of floppies,
one such use could be to write a tar-archive:
.Pp
.Dl "tar cf - . | gzip -9 | fdwrite -d /dev/fd0.1720 -v
.Pp
The main difference from using
.Xr tar 1 Ns 's
multivolume facility is of course the formatting of the floppies, which
here is done on the fly,
thus reducing the amount of work for the floppy-jockey.
.Sh SEE ALSO
.Xr fdformat 1
.Sh HISTORY
The
.Nm
utility was written while waiting for ``make world'' to complete.
Some of the code was taken from
.Xr fdformat 1 .
.Sh AUTHORS
The program has been contributed by
.An Poul-Henning Kamp Aq phk@FreeBSD.org .
.Sh BUGS
Diagnostics are less than complete at present.
.Pp
If a floppy is sick, and the
.Ar inputfile
is seekable, it should ask the user to frisbee the disk, insert
another, and rewind to the right spot and continue.
.Pp
This concept could be extended to cover non-seekable input also
by employing a temporary file.
.Pp
An option (defaulting to zero) should allow the user to ask for
retries in case of failure.
.Pp
At present a suitable tool for reading back a multivolume set
of floppies is missing.
Programs like
.Xr tar 1
for instance, will do the job, if the data has not been compressed.
One can always trust
.Xr dd 1
to help out in this situation of course.
