CDDREC(1)                       Domain/OS SysV                       CDDREC(1)



NAME
     cddrec - read Directory Record from CDROM

SYNTAX
     cddrec [-s number] [-b] file

DESCRIPTION
     This command is used to access the Directory Record associated with a
     CD-ROM file or directory and to list its contents on standard output.  If
     the command is used without the option -b, only the fixed part of the
     Directory Record is copied from the CD-ROM; this does not include the
     System Use field.

OPTIONS
     The following options are available:
     -s number  This option specifies the File Section for which the
                Directory Record shall be read. The numbering starts
                with one. If this option is omitted the last File Section
                of that file is assumed.

     -b         With this option the entirety of the Directory Record
                is copied from CD-ROM to standard output
                in binary format.

OPERANDS
     The operand file is the name of any file or directory within the CD-ROM
     file hierarchy.

STDIN
     Not used.

INPUT FILES
     None.

ENVIRONMENT VARIABLES
     LC_TIME determines the format and contents of date and time strings. If
     LC_TIME is not set in the environment or is set to the empty string, the
     value of LANG will be used as a default. If LANG is not set or is set to
     the empty string, the corresponding value from the implementation-
     specific default locale will be used. If LC_TIME or LANG contain an
     invalid setting, the utility will behave as if none of the variables had
     been defined.

STDOUT
     The output is formatted in the form of a table that contains the name of
     each field of the Directory Record and the corresponding contents of the
     entry as recorded on the CD-ROM. The System Use field is not listed.  If
     the option -b is applied, the contents of the full Directory Record is
     written to standard output in binary format as it is on the CD-ROM.

STDERR
     Used only for diagnostic messages.

OUTPUT FILES
     None.

EXIT STATUS
     The following exit values are returned:

     0       successful completion

     1       file not found, file is not within a CD-ROM file
             hierarchy, or access permission denied.

     2       File Section indicated by -s does not exist

CONSEQUENCES OF ERRORS
     None.

APPLICATION USAGE
     The user must have read permission for file to execute the command
     successfully.
