I have been working with this script (mysql_setpermissions.pl) for a while
and I chanded the path for my.cnf because in Winnt Mysql uses my.ini and
that is used for the admin program. Mysql does not automaticly use my.cnf,
so I set the path. The error I get know is:
The specified CGI application misbehaved by not returning a complete set of
HTTP headers. The headers it did return are:
syntax error at F:\web\cgi-bin\mysql_setpermission.pl line 71, near
"exit(0); # the end."
(Might be a runaway multi-line .. string starting on line 67)
Can't use global $_ in "my" at F:\web\cgi-bin\mysql_setpermission.pl line
102, near "= $_"
syntax error at F:\web\cgi-bin\mysql_setpermission.pl line 118, near "}"
Execution of F:\web\cgi-bin\mysql_setpermission.pl aborted due to
compilation errors.
This is the script:

----------------------------------------------------------------------
The permission setter for MySQL.
version: $version
made by: Luuk de Boer <luuk\@wxs.nl>
----------------------------------------------------------------------
The permission setter is a little program which can help you add users
or databases or change passwords in MySQL. Keep in mind that we don't
check permissions which already been set in MySQL. So if you can't
connect to MySQL using the permission you just added, take a look at
the permissions which have already been set in MySQL.
The permission setter first reads your .my.cnf file in your Home
directory if it exists.
Options for the permission setter:
--help : print this help message and exit.
The options shown below are used for making the connection to the MySQL
server. Keep in mind that the permissions for the user specified via
these options must be sufficient to add users / create databases / set
passwords.
--user : is the username to connect with.
--password : the password of the username.
--host : the host to connect to.
--socket : the socket to connect to.
--port : the port number of the host to connect to.
If you don't give a password and no password is set in your .my.cnf
file, then the permission setter will ask for a password.
