Hi Sheeri… mysqld_multi is broken in various ways and places, basically it has not been kept up-to date with other changes over the years.
I’ve filed bugs on it. I tripped over this (again) a few weeks ago, and when checking in the bugs system I found that it was pretty much the same issue I’d filed as a bug about a year back. So I amended it. It’s in progress now, it seems.

You know, I had thought to try that, but I’d remembered wrongly that it was “mysql_print_defaults” and could not find the program.

It would actually be

my_print_defaults mysqld_multi mysqld1 | sed -e ‘1i [mysqld]’ -e ’s/^–//’

I do believe that if this were a closed source program, though, I would not even have access to the “my_print_defaults” program, which is basically part of the code library.

The point remains: Being able to use the tools that the MySQL developers use is extremely valuable to the community, and it drives home that even though I do not hack the C code and probably never will, I am still benefiting from open source.

I’d probably use my_print_defaults for this. Something like

my_print_defaults mysqld mysqld1 | sed -e ‘1i [mysqld]’ -e ’s/^–//’
