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

NAME

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

SYNOPSIS

       mariadb-access [host_name [user_name [db_name]]] [options]

DESCRIPTION

       mariadb-access is a diagnostic tool written by Yves Carlier. It checks the access privileges for a host
       name, user name, and database combination. Note that mariadb-access 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 mariadb-access like this:

           shell> mariadb-access [host_name [user_name [db_name]]] [options]

       mariadb-access 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 mariadb-admin
           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 mariadb-access.

       •   --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, mariadb-access 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, mariadb-access 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 mariadb-access expects to find the mariadb client. Edit the mariadb-access script at approximately
       line 18. Search for a line that looks like this:

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

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