If none is given, stdin is assumed. 62.It Fl d Ar device 63The name of the floppy device to write to. Default is 64.Pa /dev/fd0 . 65.El 66.Pp 67The 68.Nm 69utility actually closes the 70.Ar device 71while it waits for the user to press return, 72it is thus quite possible to use the drive for other purposes at this 73time and later resume writing with the next floppy. 74.Pp 75The parameters returned from 76.Ar device 77are used for formatting. 78If custom formatting is needed, please use 79.Xr fdformat 1 80instead. 81.Sh EXAMPLES 82The 83.Nm 84utility 85was planned as a tool to make life easier when writing a set of floppies, 86one such use could be to write a tar-archive: 87.Pp 88.Dl "tar cf - . | gzip -9 | fdwrite -d /dev/fd0.1720 -v 89.Pp 90The main difference from using 91.Xr tar 1 Ns 's 92multivolume facility is of course the formatting of the floppies, which 93here is done on the fly, 94thus reducing the amount of work for the floppy-jockey. 95.Sh SEE ALSO 96.Xr fdformat 1 97.Sh HISTORY 98The 99.Nm 100utility was written while waiting for ``make world'' to complete. 101Some of the code was taken from 102.Xr fdformat 1 . 103.Sh AUTHORS 104The program has been contributed by 105.An Poul-Henning Kamp Aq phk@FreeBSD.org . 106.Sh BUGS 107Diagnostics are less than complete at present. 108.Pp 109If a floppy is sick, and the 110.Ar inputfile 111is seekable, it should ask the user to frisbee the disk, insert 112another, and rewind to the right spot and continue. 113.Pp 114This concept could be extended to cover non-seekable input also 115by employing a temporary file. 116.Pp 117An option (defaulting to zero) should allow the user to ask for 118retries in case of failure. 119.Pp 120At present a suitable tool for reading back a multivolume set 121of floppies is missing. 122Programs like 123.Xr tar 1 124for instance, will do the job, if the data has not been compressed. 125One can always trust 126.Xr dd 1 127to help out in this situation of course. 128
