The first thing I notice is that you do "while [ $result ]", but haven't set $result anywhere - is this present in your environment?

Also, the body of the while[$result] doesn't modify $result, so it will loop forever if $result is true on entry.

NAME
mysql_fix_privilege_tables - upgrade MySQL system tables SYNOPSIS
mysql_fix_privilege_tables --password=root_password DESCRIPTION
Note In MySQL 5.1.7, mysql_fix_privilege_tables was superseded by mysql_upgrade, which should be used instead. See mysql_upgrade(1). Some releases of MySQL introduce changes to the structure of the system tables in the mysql database to add new privileges or support new features. When you update to a new version of MySQL, you should update your system tables as well to make sure that their structure is up to date. Otherwise, there might be capabilities that you cannot take advantage of. mysql_fix_privilege_tables is an older script that previously was used to uprade the system tables in the mysql database after a MySQL upgrade. Before running mysql_fix_privilege_tables, make a backup of your mysql database. On Unix or Unix-like systems, update the system tables by running the mysql_fix_privilege_tables script: shell> mysql_fix_privilege_tables You must run this script while the server is running. It attempts to connect to the server running on the local host as root. If your root account requires a password, indicate the password on the command line like this: shell> mysql_fix_privilege_tables --password=root_password The mysql_fix_privilege_tables script performs any actions necessary to convert your system tables to the current format. You might see some Duplicate column name warnings as it runs; you can ignore them. After running the script, stop the server and restart it so that any changes made to the system tables take effect. On Windows systems, MySQL distributions include a mysql_fix_privilege_tables.sql SQL script that you can run using the mysql client. For example, if your MySQL installation is located at C:Program FilesMySQLMySQL Server 5.1, the commands look like this: C:> cd "C:Program FilesMySQLMySQL Server 5.1" C:> binmysql -u root -p mysql mysql> SOURCE share/mysql_fix_privilege_tables.sql Note Prior to version 5.1.17, the mysql_fix_privilege_tables.sql script is found in the scripts directory. The mysql command will prompt you for the root password; enter it when prompted. If your installation is located in some other directory, adjust the path names appropriately. As with the Unix procedure, you might see some Duplicate column name warnings as mysql processes the statements in the mysql_fix_privilege_tables.sql script; you can ignore them. After running the script, stop the server and restart it. COPYRIGHT
