mg@mg-laptop:~$ sudo mount -t auto /dev/cdrom /media/cdrom0
[sudo] password for mg:
mount: si deve specificare il tipo di filesystem
mg@mg-laptop:~$ sudo mount -t iso9660 auto /dev/cdrom /media/cdrom0
Usage: mount -V                : print version
      mount -h                : print this help
      mount                    : list mounted filesystems
      mount -l                : idem, including volume labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
      mount -a [-t|-O] ...    : mount all stuff from /etc/fstab
      mount device            : mount device at the known place
      mount directory          : mount known device here
      mount -t type dev dir    : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
      mount --bind olddir newdir
or move a subtree:
      mount --move olddir newdir
One can change the type of mount containing the directory dir:
      mount --make-shared dir
      mount --make-slave dir
      mount --make-private dir
      mount --make-unbindable dir
One can change the type of all the mounts in a mount subtree
containing the directory dir:
      mount --make-rshared dir
      mount --make-rslave dir
      mount --make-rprivate dir
      mount --make-runbindable dir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using  -L label  or by uuid, using  -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say  man 8 mount .
