Toggle verbosity on stdout. Default is on. After 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.
-y
Do not ask for presence of a floppy disk in the drive. This non-interactive flag is useful for shell scripts.
-f inputfile
Input file to read. If none is given, stdin is assumed.
-d device
The name of the floppy device to write to. Default is /dev/fd0.
The fdwrite utility actually closes the 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 device are used for formatting. If custom formatting is needed, please use fdformat(1) instead.
