Looks good to me so far, no more errors on the iMac. :)

With so many people asking for error messages to go to stderr, I have to admit I was wrong and just do it. Can you try the attached patch? Thanks.

I'm running dmidecode on an iMac, and get the following error message at the end of the output:

Invalid entry length (0). DMI table is broken! Stop.

Since this message is printed to stdout, it's a little cumbersome to get e.g. the system-uuid in scripts, since it looks like this:

# dmidecode -q -s system-uuid 2>/dev/null
Invalid entry length (0). DMI table is broken! Stop.

You'd need some extra work using e.g. grep to make sure to get the UUID only, without trailing garbage.

I think this error should be printed to stderr, at least when using the -s command line switch. I also noticed the exit code is 0, but maybe this should be kept this way as long as the table could be parsed up until the point where the requested info lies.

This is very similar to #47274, and maybe there are more instances where errors go to stdout; could only spot one more instance at a quick glance however.
