Hi everybody,

How can I kill a busy cdrom. Last nite when I want to "umount" my cdrom, my RedHat7.2 said the cdrom is busy but there was nothing using it. So I have to reboot to able me to eject my cdrom.


One more thing, I can't do :-
"shutdown" at command promt. the "bash" said that the command couldn't be found. How can I resolve this? F.Y.I I already tried to be "root" too. The funny thing is my Xwindow can do it's shutdown. I'm using GNOME



How can I format my floppy. when I use "fdformat" the flopy can't be use untill I format back in dos.thanks

Make sure that you aren't "in" the CD in some way (cd'd to it in term window, actively browsing it in a file manager, etc.).

Weird...does the halt command work? Make sure the command exists (can't see why it wouldn't):
locate shutdown
whereis shutdown
find / -name shutdown

Then make sure that the directory in which the command lives is in your PATH (or type the fully-qualified pathname):
echo $PATH

If not:
export PATH="$PATH:/path/to/shutdown/command

When you say it can't be used, what do you mean? Do you get errors, or is it just "not there"?
