Today I noticed that some time in the past I mounted an ISO, but forgot which one it was:

/dev/loop0 on /export/production/os/iso/centos/mount type iso9660 (rw)

How can I find the exact file name that is mounted on /dev/loop0?

losetup /dev/loop0

produces something like:

/dev/loop0: [000f]:8070558 (/path/to/file.iso)

losetup comes with the util-linux package.

losetup -a will probably tell you what you need
