$ Linux Command

Files

volname

Print the volume name of an ISO 9660 image.

isovolumenamecdromdisc

Additional Notes

volname reads an ISO 9660 filesystem image (typically a CD-ROM or DVD image) and prints its volume name (volume descriptor label). The volume name is the human-readable label assigned when the ISO image was created.

This is useful for identifying ISO files without mounting them. The command reads the primary volume descriptor from the ISO image and extracts the volume identifier field, which can be up to 32 characters long.

Syntax

volname [iso-file]

Parameters

  • iso-file: Path to an ISO 9660 image file. If omitted, reads from standard input.

Examples

volname disk.iso

Print the volume name of disk.iso.

volname < /dev/cdrom

Read the volume name directly from a CD-ROM device.

for iso in *.iso; do echo "$(volname "$iso") - $iso"; done

List volume names for all ISO files in the directory.

Practical Notes

  • volname only works with ISO 9660 filesystems (standard CD/DVD format). It does not handle UDF, HFS, or other filesystem types.
  • For UDF images (common for Blu-ray), use blkid or isoinfo.
  • The volume name is set during ISO creation with mkisofs -V "VOLUME_NAME".
  • Most graphical disk tools and file command also display the volume label.
  • volname is part of the cdrkit or genisoimage package on most distributions.
