Maybe it's an stupid question but remeber... I'm Junior..
I use command line to run programs, and some of them gives a lot of information when, for example, you open a window or other actions. That's really bad because my terminal gets full of unwanted messages, so I use "bin file & >/dev/null"... (1 Reply)

fdformat
FDFORMAT(8) System Administration FDFORMAT(8)
NAME
fdformat - low-level format a floppy disk
SYNOPSIS
fdformat [options] device
DESCRIPTION
fdformat does a low-level format on a floppy disk. device is usually one of the following (for floppy devices the major = 2, and the minor
is shown for informational purposes only):
/dev/fd0d360 (minor = 4)
/dev/fd0h1200 (minor = 8)
/dev/fd0D360 (minor = 12)
/dev/fd0H360 (minor = 12)
/dev/fd0D720 (minor = 16)
/dev/fd0H720 (minor = 16)
/dev/fd0h360 (minor = 20)
/dev/fd0h720 (minor = 24)
/dev/fd0H1440 (minor = 28)
/dev/fd1d360 (minor = 5)
/dev/fd1h1200 (minor = 9)
/dev/fd1D360 (minor = 13)
/dev/fd1H360 (minor = 13)
/dev/fd1D720 (minor = 17)
/dev/fd1H720 (minor = 17)
/dev/fd1h360 (minor = 21)
/dev/fd1h720 (minor = 25)
/dev/fd1H1440 (minor = 29)
The generic floppy devices, /dev/fd0 and /dev/fd1, will fail to work with fdformat when a non-standard format is being used, or if the for-
mat has not been autodetected earlier. In this case, use setfdprm(8) to load the disk parameters.
OPTIONS
-n, --no-verify
Skip the verification that is normally performed after the formatting.
-V, --version
Output version information and exit.
-h, --help
Display help and exit.
