■ OS Environment : Linux[RHEL, Centos]
■ Implementation Steps :
In Unix-like operating systems, a loop device, vnd (vnode disk), or lofi (loopback file interface) is a pseudo-device that makes a file accessible as a block device.
$losetup /dev/loop0 example.img
$ mount /dev/loop0 /home/you/dir
The second command mounts the device on the directory /home/you/dir. The overall effect of executing these two commands is that the content of the file is used as a file system rooted at the mount point.
The mount utility is usually capable of handling the entire procedure:
mount -o loop example.img /home/you/dir
