Welcome to the Exciting World Of Installer Writing :-) I'd recommend, in order, 1) take Greg Willits' suggestion to look at embedded MySql rather than try to deal with the vagaries of a possible existing installation, or 2) get a good shell (sh/bash) scripting book. It's possible to do what you want fairly reliably but it's a lot more than a one-liner! And OT for this list, too. P.S. Is the host name in my example "local" or "John-Mistlers-Computer.local"? I believe this reflects some OS X wierdness, in that 'local' is a dummy domain name, and the hostname is 'John-Mistlers-Computer'. I am not a Mac person, this Powerbook's just a loaner for a project, so you probably want to confirm that with some testing. Or ask on a Mac-oriented dev list.

Re: Mac Developer Question
I'm having trouble getting this line to work. I have tried: kill `cat /usr/local/mysql/bin/mysql/data/localhost.pid` -> Not a directory kill `cat /usr/local/mysql/data/localhost.pid` -> Permission denied I'm not sure if I have the wrong hostname, or if the command is more flawed than that. Furthermore, I need the command to work without requiring a password or other response, because it is issued as a unix shell command to initiate resetting the root password: do shell script "kill `cat /usr/local/mysql/bin/mysql/data/localhost.pid`" do shell script "/usr/local/mysql./bin/mysqld_safe --skip-grant-tables &" do shell script "/usr/local/mysql/bin/mysqladmin -u root flush-priveleges password '"&rootPassword&"'" do shell script "/usr/local/mysql/bin/mysqladmin shutdown do shell script "/usr/local/mysql./bin/mysqld_safe" on 5/22/04 7:52 AM, Paul Bingman at [EMAIL PROTECTED] wrote: > On Sat, 22 May 2004, John Mistler wrote: > >> do shell script "kill cat /usr/local/mysql/bin/mysql/data/localhost.pid" > > The kill command takes a numeric PID as its argument.

Ideally, I would like for the application to come packaged with MySQL, to install MySQL automatically (not sure what happens if MySQL already exists on the system), and to never ask the user for a password. In fact, to just run MySQL in the background as if it were a part of my application. Any ideas on this? However, in the short term, in order to get it all working on my own computer I will need to get the above language correct. You should be looking into the embedded version of MySQL which is aimed exactly at these purposes. -- greg willits -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

You need to get the pid out of the pidfile. So to get the above to work you have to enclose cat and the filename in backticks: kill `cat /usr/local/mysql/bin/mysql/data/localhost.pid` This will run "cat /usr/local/mysql/bin/mysql/data/localhost.pid", getting the numeric pid from the file, then pass the pid to kill. paul -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
