Flush all logs\&.
.sp
The
\fBmysqladmin flush\-logs\fR
command permits optional log types to be given, to specify which logs to flush\&. Following the
flush\-logs
command, you can provide a space\-separated list of one or more of the following log types:
binary,

slow\&. These correspond to the log types that can be specified for the

.sp
This is like the
password
command but stores the password using the old (pre\-4\&.1) password\-hashing format\&. (See

password \fInew_password\fR
.sp
Set a new password\&. This changes the password to
\fInew_password\fR
for the account that you use with
\fBmysqladmin\fR
for connecting to the server\&. Thus, the next time you invoke
\fBmysqladmin\fR
(or any other client program) using the same account, you will need to specify the new password\&.

.nr an-break-flag 1
.br
.ps +1
\fBWarning\fR
.ps -1
.br
Setting a password using
\fBmysqladmin\fR
should be considered
\fIinsecure\fR\&. 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\&. Also, on some systems this overwriting strategy is ineffective and the password remains visible to
\fBps\fR\&. (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
shell> \fBmysqladmin password "my new password"\fR
.fi
.if n \{\
.RE
.\}
.sp
In MySQL 5\&.7, 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\&. Omitting the password value should be done only if
password
is the final command on the
\fBmysqladmin\fR
command line\&. Otherwise, the next argument is taken as the password\&.
.if n \{\
.sp
.\}
.RS 4
.it 1 an-trap
.nr an-no-space-flag 1
.nr an-break-flag 1
.br
.ps +1
\fBCaution\fR
.ps -1
.br
Do not use this command used if the server was started with the
\fB\-\-skip\-grant\-tables\fR
option\&. No password change will be 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\&.
