This section will discuss how to mount or unmount a file system. The file systems
on your hard drives are normally mounted as a part of the boot
process. Typical the only file systems you manually mount or unmount are for the CD and floppy drives.
- The mount command allows a file system to be accessed.
- You must know know the device name where the file system resides and
have a directory already created that is used to access the file system.
- For a CD, the typical device is /dev/sud0 and the directory is /cdrom.
- For a floppy, the typical device is /dev/fd and the directory is /floppy.
- mount /dev/sud0 /cdrom - Mounts the file system
/dev/sud0 in the directory /cdrom
- mount /dev/fd /floppy
- Mounts the file system /dev/fd in the directory /floppy
Note: The command df
displays mounted file systems and the directory they are mounted in.
The umount disables the access to a file system. If you mounted a CD,
you will not be able to open the CD tray until you un-mount
the CD file system. To un-mount, you only need to know the directory for the mounting point.
Example: umount /cdrom
