+.SH "NAME"
+mariadb-check \- a table maintenance program (mysqlcheck is now a symlink to mariadb-check)
+.SH "SYNOPSIS"
+.HP \w'\fBmysqlcheck\ [\fR\fB\fIoptions\fR\fR\fB]\ [\fR\fB\fIdb_name\fR\fR\fB\ [\fR\fB\fItbl_name\fR\fR\fB\ \&.\&.\&.]]\fR\ 'u
+\fBmysqlcheck [\fR\fB\fIoptions\fR\fR\fB] [\fR\fB\fIdb_name\fR\fR\fB [\fR\fB\fItbl_name\fR\fR\fB \&.\&.\&.]]\fR
+.SH "DESCRIPTION"
+.PP
+The
+\fBmysqlcheck\fR
+client performs table maintenance: It checks, repairs, optimizes, or analyzes tables\&.
+.PP
+Each table is locked and therefore unavailable to other sessions while it is being processed, although for check operations, the table is locked with a
+READ
+lock only\&. Table maintenance operations can be time\-consuming, particularly for large tables\&. If you use the
+\fB\-\-databases\fR
+or
+\fB\-\-all\-databases\fR
+option to process all tables in one or more databases, an invocation of
+\fBmysqlcheck\fR
+might take a long time\&. (This is also true for
+\fBmysql_upgrade\fR
+because that program invokes
+\fBmysqlcheck\fR
+to check all tables and repair them if necessary\&.)
+.PP
+\fBmysqlcheck\fR
+is similar in function to
+\fBmyisamchk\fR, but works differently\&. The main operational difference is that
+\fBmysqlcheck\fR
+must be used when the
+\fBmysqld\fR
+server is running, whereas
+\fBmyisamchk\fR
+should be used when it is not\&. The benefit of using
+\fBmysqlcheck\fR
+is that you do not have to stop the server to perform table maintenance\&.
+.PP
+\fBmysqlcheck\fR
+uses the SQL statements
+CHECK TABLE,
+REPAIR TABLE,
+ANALYZE TABLE, and
+OPTIMIZE TABLE
+in a convenient way for the user\&. It determines which statements to use for the operation you want to perform, and then sends the statements to the server to be executed\&.
+.PP
+The
+MyISAM
+storage engine supports all four maintenance operations, so
+\fBmysqlcheck\fR
+can be used to perform any of them on
+MyISAM
+tables\&. Other storage engines do not necessarily support all operations\&. In such cases, an error message is displayed\&. For example, if
+test\&.t
+is a
+MEMORY
+table, an attempt to check it produces this result:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+shell> \fBmysqlcheck test t\fR
+test\&.t
+note : The storage engine for the table doesn't support check
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+If
+\fBmysqlcheck\fR
+is unable to repair a table, see the MariaDB Knowledge Base
+for manual table repair strategies\&. This will be the case, for example, for
+InnoDB
+tables, which can be checked with
+CHECK TABLE, but not repaired with
+REPAIR TABLE\&.
+.PP
+The use of
+\fBmysqlcheck\fR
+with partitioned tables is not supported\&.

+.PP
+It is best to make a backup of a table before performing a table repair operation; under some circumstances the operation might cause data loss\&. Possible causes include but are not limited to file system errors\&.

+.PP
+There are three general ways to invoke
+\fBmysqlcheck\fR:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+shell> \fBmysqlcheck [\fR\fB\fIoptions\fR\fR\fB] \fR\fB\fIdb_name\fR\fR\fB [\fR\fB\fItbl_name\fR\fR\fB \&.\&.\&.]\fR
+shell> \fBmysqlcheck [\fR\fB\fIoptions\fR\fR\fB] \-\-databases \fR\fB\fIdb_name\fR\fR\fB \&.\&.\&.\fR
+shell> \fBmysqlcheck [\fR\fB\fIoptions\fR\fR\fB] \-\-all\-databases\fR
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+If you do not name any tables following
+\fIdb_name\fR
+or if you use the
+\fB\-\-databases\fR
+or
+\fB\-\-all\-databases\fR
+option, entire databases are checked\&.
+.PP
+\fBmysqlcheck\fR
+has a special feature compared to other client programs\&. The default behavior of checking tables (\fB\-\-check\fR) can be changed by renaming the binary\&. If you want to have a tool that repairs tables by default, you should just make a copy of
+\fBmysqlcheck\fR
+named
+\fBmysqlrepair\fR, or make a symbolic link to
+\fBmysqlcheck\fR
+named
+\fBmysqlrepair\fR\&. If you invoke
+\fBmysqlrepair\fR, it repairs tables\&.
+.PP
+The following names can be used to change
+\fBmysqlcheck\fR
+default behavior\&.
