This non-interactive flag 55is useful for shell scripts. 56.It Fl f Ar inputfile 57Input file to read. If none is given, stdin is assumed. 58.It Fl d Ar device 59The name of the floppy device to write to. Default is ``/dev/rfd0''. 60.El 61 62.Nm Fdwrite 63actually closes the 64.Ar device 65while it waits for the user to press return, 66it is thus quite possible to use the drive for other purposes at this 67time and later resume writing with the next floppy. 68 69The parameters returned from 70.Ar device 71are used for formatting. 72If custom formatting is needed, please use 73.Xr fdformat 1 74instead. 75 76.Sh EXAMPLE 77.Nm Fdwrite 78was planned as a tool to make life easier when writing a set of floppies, 79one such use could be to write a tar-archive: 80 81.ce 1 82tar cf - . | gzip -9 | fdwrite -d /dev/rfd0.1720 -v 83 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 90.Sh SEE ALSO 91.Xr fdformat 1 92.Sh HISTORY 93.Nm Fdwrite 94was written while waiting for ``make world'' to complete. 95Some of the code was taken from 96.Xr fdformat 1 . 97.Sh AUTHORS 98The program has been contributed by 99.An Poul-Henning Kamp Aq phk@login.dknet.dk . 100.Sh BUGS 101Diagnostics are less than complete at present. 102 103If a floppy is sick, and the 104.Ar inputfile 105is seekable, it should ask the user to frisbee the disk, insert 106another, and rewind to the right spot and continue. 107 108This concept could be extended to cover non-seekable input also 109by employing a temporary file. 110 111An option (defaulting to zero) should allow the user to ask for 112retries in case of failure. 113 114At present a suitable tool for reading back a multivolume set 115of floppies is missing. 116Programs like 117.Xr tar 1 118for instance, will do the job, if the data has not been compressed. 119One can always trust 120.Xr dd 1 121to help out in this situation of course. 122
