Note: This answer, or a better one should probably go into the FAQ, this  
question (and other related ones, such as "my floppy is stuck I can't eject  
it") is asked a lot.

When you use the tar command from the shell, specify /dev/rfd0b (for example to  
read the table of contents on a floppy: "tar tf /dev/rfd0b"). The man page on  
tar goes into more detail about the specifics. Don't insert the floppy, just  
type your tar command, and NeXTSTEP will politely ask you to insert the disk.

Now, you need to set the permissions on /dev/rfd0b to rw for whoever is using  
it. To do everyone (note /dev/rfd0b is owned by root):

% chmod 666 /dev/rfd0b
% ls -alsx /dev/rfd0b
   0 crw-rw-rw-  1 root      41,  1 Nov  4 10:23 /dev/rfd0b
%

If you don't want to set the permissions, you have to run tar as root.

To eject the disk, there is a command somewhere, sorry I can't remember what it  
is. However, a bit of hacking will get it ejected for you (see man page on fd  
et al for more info).

Here's a program, name the source eject.m and do what the comments say.

-------------cut for eject.m-----------------
#include <stdio.h>
#include <sys/file.h>
#include <bsd/dev/disk.h>
#include <bsd/dev/fd_extern.h>

// save this file as eject.m
// % make eject		# Make a binary (no makefile required)
// % strip ./eject	# Shrink the binary
// % ./eject 		# to eject the disk
// As long as /dev/rfd0b is crw-rw-rw- this will work, else
// run this program as root.

void
main (int argc, char** argv)
{
    int fd = open ("/dev/rfd0b", O_RDONLY,  0);
    ioctl (fd, DKIOCEJECT);
    close (fd);
    exit (0);
}

-----------------end eject.m-------------
