I am wrong -- virtual optical drive for Linux

In Linux, you can directly mount the virtual Optical Drive.

Reference:
Ubuntu Linux does not require us to install the virtual optical drive software. It can be easily done with simple Mount commands without additional downloads. For example, to use a virtual file. ISO file, run the following command on the command line:
First, create a folder for storing the ISO file. We have created this folder/Media/ISO
Sudo mkdir/Media/ISO
Mount file. ISO:
Sudo mount file. ISO/Media/ISO/-T iso9660-o loop
Now we can see the file. ISO file in/Media/ISO.
To uninstall the image file. ISO, run the following command:
Sudo umount/Media/ISO/

After an afternoon, I found that the above method was not feasible and always prompted that the format was incorrect.
So I searched for the loop device and the virtual optical drive on the Forum and Google.

The following are your solutions:

first


sudo losetup-D/dev/loop *


* indicates the number of loop devices


you can use sudo losetup-F to find the first available loop device



the following uses loop0 as an example, to load/homeoem/amule/bsci_a.iso to/home/OEM/bcmsn_a/:


sudo losetup-D/dev/loop0


sudo losetup/dev/loop0/home/OEM/amule/bsci_a.iso


sudo Mount/dev/loop0/home/OEM/bcmsn_a/


as long as there are enough loop devices, you can keep working on it.
