I am doing a mounting of an iso file and looking at this tutorial. They use the command:
$ mount -o loop disk1.iso /mnt/disk
I'm trying to understand the use of
-o loop. So I have two questions:
When I look at the long man page for mount, it takes time to find that
-o option. If I do
man mount | grep "-o" I get and error, and when I look in the file I do not find info that "loop" is a command text for option
-o. Where is that documented?
Also, what is the "loop device" concept for mounting? Even a good link to an explanation would be appreciated.
