cdrom command
 

:Pengy:
would anyone please tell me what command should I use to see where my cdrom and cdwriter are install.
I try /etc/fstab it gives me an error message, such as permission is denied.

fstab should give you the info you might need. how are you trying to access fstab, its a text file so you need to open it with a text editor or with vi or something from the command line.
nothing should be permitting you not to view the file, if so cahnge your permission settings or su into root.

/etc/fstab is not an executable file. It is a data file. Use cat /etc/fstab to see what is in it.
