losetup: List loop devices with detailed info.
$ losetup -a
try on your machine
The command "losetup -a" is used to show all the active loop devices that have been set up on a Linux system.
A loop device is a pseudo-device that allows a file to be accessed as a block device. It enables treating regular files like disk devices and provides a way to mount filesystems contained within these files.
When you run the "losetup -a" command, it lists all the loop devices that are currently in use on the system. The output typically includes information about each loop device such as the device name (e.g., /dev/loop0), the file associated with it, and the offset and size of the file within the device.
