How do you mount a hard disk from the command line as read-only? I don't want or need a link to the man page, I want the exact thing I will have to type in if the following is true:

disk to mount is on /dev/sda

it is 2 TB
-it is critical that I mount it read-only and not read-write. Very critical.

I'm doing it from a live Ubuntu CD so I have no business to edit the fstab or any file for that matter

You do not mount /dev/sda, that refers to the entire disk. You mount /dev/sda1 or whatever partition you want.

Make a mount point, call it anything you like.

sudo mkdir /media/2tb

Mount

sudo mount -o ro /dev/sda1 /media/2tb

When your done, you should unmount the disk

sudo umount /media/2tb

See man mount or https://help.ubuntu.com/community/Fstab
