CDR(8) BSD System Manager's Manual CDR(8)NAME
cdr - CD-Recordable drive control program
SYNOPSIS
cdr [-f device] -c command [-P parameter=value,...] [-d] [-p
parameter,...] [-v parameter,...] [-x]
DESCRIPTION
This command is used to run SCSI commands on a specified device as a di-
agnostic. The structure and use of this command is identical to
scsicmd(8), with the addition of commands specific to CD-Recordable
drives and the error code table extended to include the common error mes-
sages returned by CDRs.
This command is not intended for general use, but is convenient as a di-
agnostic tool for the expert user. Typically, the cdread(8) and cd-
write(8) commands should be used instead.
ENVIRONMENTCDR The default device filename. It may be overridden with -f.
DIAGNOSTICS
Among its many messages about consistency of arguments and so on, cdr
will print a message beginning ``scsi status:'' if a command fails for
some reason.

BUGS
None known, but it's certainly possible. The interface is clumsy and
suitable only for expert users.
