YEP -confirmed!! - even if you use a different linux login user and a different mysql user.
Sure it was a different Linux user? I realized that the Unix user is having a $HOME/.mysql_history which gets updated when you close the mysql CLI. That makes sense and explains why I could see the commands of a different MySQL user.
But then I logged out of MariaDB only and logged in again.... and it did NOT do it anymore, using same user. Does not seem to be consistent behaviour??
If you really have a different Linux user - maybe it is shared memory somewhere that gets cleared? But I cannot reproduce it with a different Unix user - so it's just noise from my side. Sorry about that Peter
