On some systems, your password becomes visible to system status programs such as \fBps\fR that may be invoked by other users to display command lines\&. MySQL clients typically overwrite the command\-line password argument with zeros during their initialization sequence\&. However, there is still a brief interval during which the value is visible\&.

(SystemV Unix systems and perhaps others are subject to this problem\&.) .sp .5v .RE If the \fInew_password\fR value contains spaces or other characters that are special to your command interpreter, you need to enclose it within quotation marks\&. On Windows, be sure to use double quotation marks rather than single quotation marks; single quotation marks are not stripped from the password, but rather are interpreted as part of the password\&. For example: .sp .if n \{\ .RS 4 .\} .nf mysqladmin password "my new password" .fi .if n \{\ .RE .\} .sp The new password can be omitted following the password command\&. In this case, \fBmysqladmin\fR prompts for the password value, which enables you to avoid specifying the password on the command line\&.

No password change is applied\&. This is true even if you precede the password command with flush\-privileges on the same command line to re\-enable the grant tables because the flush operation occurs after you connect\&. However, you can use \fBmysqladmin flush\-privileges\fR to re\-enable the grant table and then use a separate \fBmysqladmin password\fR command to change the password\&. .sp .5v .RE .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} ping .sp Check whether the server is available\&.
