**MARIADB-ACCESS**(1) MariaDB Database System **MARIADB-ACCESS**(1)

# [NAME](#NAME)

mariadb-access - client for checking access privileges (mysqlaccess is now a symlink to mariadb-access)

# [SYNOPSIS](#SYNOPSIS)

**mysqlaccess \[host\_name \[user\_name \[db\_name]]] \[options]**

# [DESCRIPTION](#DESCRIPTION)

**mysqlaccess** is a diagnostic tool written by Yves Carlier. It checks the access privileges for a host name, user name, and database combination. Note that **mysqlaccess** checks access using only the user, db, and host tables. It does not check table, column, or routine privileges specified in the tables\_priv, columns\_priv, or procs\_priv tables.

Invoke **mysqlaccess** like this:

```
shell> mysqlaccess [host_name [user_name [db_name]]] [options]
```

**mysqlaccess** supports the following options.

•**--help**, **-?**

Display a help message and exit.

•**--brief**, **-b**

Generate reports in single-line tabular format.

•**--commit**

Copy the new access privileges from the temporary tables to the original grant tables. The grant tables must be flushed for the new privileges to take effect. (For example, execute a **mysqladmin reload** command.)

•**--copy**

Reload the temporary grant tables from original ones.

•**--db=db\_name**, **-d db\_name**

Specify the database name.

•**--debug=N**

Specify the debug level. *N* can be an integer from 0 to 3.

•**--host=host\_name**, **-h host\_name**

The host name to use in the access privileges.

•**--howto**

Display some examples that show how to use **mysqlaccess**.

•**--old\_server**

Connect to a very old MySQL server (before MySQL 3.21) that does not know how to handle full WHERE clauses.

•**--password\[=password]**, **-p\[password]**

The password to use when connecting to the server. If you omit the *password* value following the **--password** or **-p** option on the command line, **mysqlaccess** prompts for one.

Specifying a password on the command line should be considered insecure. See Section 5.3.2.2, “End-User Guidelines for Password Security”.

•**--plan**

Display suggestions and ideas for future releases.

•**--preview**

Show the privilege differences after making changes to the temporary grant tables.

•**--relnotes**

Display the release notes.

•**--rhost=host\_name**, **-H host\_name**

Connect to the MariaDB server on the given host.

•**--rollback**

Undo the most recent changes to the temporary grant tables.

•**--spassword\[=password]**, **-P\[password]**

The password to use when connecting to the server as the superuser. If you omit the *password* value following the **--spassword** or **-p** option on the command line, **mysqlaccess** prompts for one.

Specifying a password on the command line should be considered insecure. See Section 5.3.2.2, “End-User Guidelines for Password Security”.

•**--superuser=user\_name**, **-U user\_name**

Specify the user name for connecting as the superuser.

•**--table**, **-t**

Generate reports in table format.

•**--user=user\_name**, **-u user\_name**

The user name to use in the access privileges.

•**--version**, **-v**

Display version information and exit.

If your MariaDB distribution is installed in some non-standard location, you must change the location where **mysqlaccess** expects to find the **mysql** client. Edit the mysqlaccess script at approximately line 18. Search for a line that looks like this:

```
$MYSQL     = '/usr/local/bin/mysql';    # path to mysql executable
```

Change the path to reflect the location where **mysql** actually is stored on your system. If you do not do this, a Broken pipe error will occur when you run **mysqlaccess**.
