If none is given, stdin is assumed. 59.It Fl d Ar device 60The name of the floppy device to write to. Default is 61.Pa /dev/fd0 . 62.El 63.Pp 64.Nm Fdwrite 65actually closes the 66.Ar device 67while it waits for the user to press return, 68it is thus quite possible to use the drive for other purposes at this 69time and later resume writing with the next floppy. 70.Pp 71The parameters returned from 72.Ar device 73are used for formatting. 74If custom formatting is needed, please use 75.Xr fdformat 1 76instead. 77.Sh EXAMPLES 78.Nm Fdwrite 79was planned as a tool to make life easier when writing a set of floppies, 80one such use could be to write a tar-archive: 81.Pp 82.Dl "tar cf - . | gzip -9 | fdwrite -d /dev/fd0.1720 -v 83.Pp 84The main difference from using 85.Xr tar 1 's 86multivolume facility is of course the formatting of the floppies, which 87here is done on the fly, 88thus reducing the amount of work for the floppy-jockey. 89.Sh SEE ALSO 90.Xr fdformat 1 91.Sh HISTORY 92.Nm Fdwrite 93was written while waiting for ``make world'' to complete. 94Some of the code was taken from 95.Xr fdformat 1 . 96.Sh AUTHORS 97The program has been contributed by 98.An Poul-Henning Kamp Aq phk@login.dknet.dk . 99.Sh BUGS 100Diagnostics are less than complete at present. 101.Pp 102If a floppy is sick, and the 103.Ar inputfile 104is seekable, it should ask the user to frisbee the disk, insert 105another, and rewind to the right spot and continue. 106.Pp 107This concept could be extended to cover non-seekable input also 108by employing a temporary file. 109.Pp 110An option (defaulting to zero) should allow the user to ask for 111retries in case of failure. 112.Pp 113At present a suitable tool for reading back a multivolume set 114of floppies is missing. 115Programs like 116.Xr tar 1 117for instance, will do the job, if the data has not been compressed. 118One can always trust 119.Xr dd 1 120to help out in this situation of course. 121
