  1. Usage
  2. Options
  3. Note

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.


mariadb-access [host [user [db]]] OPTIONS

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: <<code> $MYSQL = ´/usr/local/bin/mariadb; # path to mariadb executable <</code>> 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.
