  I would do it using a log file. The command line in cron :

{ echo starting; if cdrecord blah blah blah 2>&1; then echo SUCCESS;
else echo FAILURE; echo "Cdrecord failure (`date`), check
$HOME/.cdrecord.log for details." >&2; fi; } | sed "s#^#`date`
cron-cdrecord $$: #" >>$HOME/.cdrecord.log

  Obviously, you'll have to setup logrotate to rotate your
$HOME/.cdrecord.log log file.
  And, well, that's some cron command ;)


  Or you could use a temp file, but i don't like it :

cdrecord blah blah blah &>$HOME/.cdrecord.log || cat $HOME/.cdrecord.log


  I prefer the log file way because it keeps an history of cdrecord
logs, always useful when you have a problem.
