       NAME
             cdvd - read the CD-ROM Primary Volume Descriptor

       SYNOPSIS
             cdvd [-b] file

       DESCRIPTION
             cdvd reads the Primary Volume Descriptor from the CD-ROM and
             produces a table that lists each field and its contents. If
             the -b option is not used, the Application Use field is not
             listed because it may contain non-printable characters.

             file  A file or directory in the CD-ROM file system, or a
                   block special file that holds a CD-ROM file system.

             -b    Copies the entire Primary Volume Descriptor from CD-ROM
                   to standard output in binary format, including the
                   Application Use field.

          Environment Variables
             IF LC_TIME (which determines the format and contents of the
             date and time strings) is not set or is set to the empty
             string, then cdvd uses the value of LANG.  If LANG is not set,
             or is set to the empty string, cdvd uses the value from the
             implementation-specific default locale.  If both LC_TIME and
             LANG contain invalid settings, cdvd behaves as if all of the
             variables are undefined.

          Exit Codes
