However, I have to manage 90+ website on that server, and a lot of them have custom scripting that requires a database connection. Like most people I store the connections in their own file… which couldn’t be accounted for in MT’s sweep.

Not a big deal, I logged into SSH and put SED to work, here’s the example:

from the doamins/ directory….

find ./ -name 'connect.php' -type f -exec sed -i 's/oldpassword/newpassword/g' {} \;

And let that sucker run and do the work, it swapped out all instances of the old password with the new password… gotta love automation.
