Upgrading 5.5.23 to 5.6.11 I see this while running mysql_upgrade:

Running 'mysqlcheck' with connection arguments: '--socket=/path/to/mysql.sock' '--socket=/path/to/mysql.sock' 
Warning: Using a password on the command line interface can be insecure.

However, I did not pass a password on the command line. Access to this server is configured via a ~/.my.cnf file which does have the password so the message that's given is wrong or needs adjusting.

How to repeat:
Create a ~/.my.cnf config file for access to MySQL with the following credentials:


Notice how when you run mysql_upgrade without any parameters how you get this message.

Suggested fix:
If no password is provided on the command line don't produce this message. The description is wrong. If you want to suggest that the password is not stored in the ~/.my.cnf word the warning differently.

Not critical obviously but if you want to complain about user behaviour do so correctly.

Hi Simon,

I agree that the message is a bit misleading. It can even happen using the --skip-password option. So the message should be fixed. Verified bug. Thanks for reporting this.

Best regards,

    WL#7308: Refactor mysql_upgrade
    mysql_upgrade should not call other applications by command line (as it makes password being visible).
