it onto a bunch of floppies in a semi-intelligent way. Useful for things like: tar cf - . | gzip -9 | fdwrite -d /dev/rfd0.1720 -v Where it will keep asking for floppies until tar is done.

|
|
.Sh NAME
|
|
.Nm fdwrite
|
|
.Nd format and write floppy disks
|
|
.Sh SYNOPSIS
|
|
.Nm fdwrite
|
|
.Bq Fl v
|
|
.Bq Fl f Ar inputfile
|
|
.Bq Fl d Ar device
|
|
.Sh DESCRIPTION
|
|
.Nm Fdwrite
|
|
formats and writes one and more floppy disks.
|
|
Any floppy disk device capable of formatting can be used.
|
|
|
|
.Nm Fdwrite
|
|
will ask the user
|
|
.Pq on /dev/tty
|
|
to insert a new floppy and press return.
|
|
The device will then be opened, and queried for it's paramters,
|
|
then each track will be formatted, written with data from the
|
|
.Ar inputfile ,
|
|
read back and compared.
|
|
When the floppy disk if filled, the process is repeated, with the next disk.
|
|
This continues until the program is interrupted or EOF is encountered on the
|
|
.Ar inputfile .
|
|
|
|
The options are as follows:
|
|
.Bl -tag -width 10n -offset indent
|
|
.It Fl v
|
|
toggles 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 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 ``/dev/rfd0''.
|
|
.El
|
|
|
|
.Nm Fdwrite
|
|
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.
|
|
|
|
The parameters returned from
|
|
.Ar device
|
|
are used for formatting.
|
|
If custom formatting is needed, please use
|
|
.Xr fdformat 1
|
|
instead.
|
|
|
|
.Sh EXAMPLE
|
|
.Nm Fdwrite
|
|
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:
|
|
|
|
.ce 1
|
|
tar cf - . | gzip -9 | fdwrite -d /dev/rfd0.1720 -v
|
|
|
|
The main difference from using
|
|
.Xr tar 1 '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
|
|
.Nm Fdwrite
|
|
was written while waiting for ``make world'' to complete.
|
|
Some of the code was taken from
|
|
.Xr fdformat 1 .
|
|
.Sh AUTHOR
|
|
The program has been contributed by
|
|
Poul-Henning Kamp <phk@login.dknet.dk>
|
|
.Sh BUGS
|
|
Diagnostics are less than complete at present.
|
|
|
|
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.
|
|
|
|
This concept could be extended to cover non-seekable input also
|
|
by employing a temporary file .
|
|
|
|
An option (defaulting to zero) should allow the user to ask for
|
|
retries in case of failure.
|
|
|
|
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
