Using Terminal in Mac OS X Snow Leopard, I have changed my path by adding a file to the /etc/paths.d directory. One way to make this take effect is to logout, then log back in.
However, I have used another method in the past, but can't remember what it was. There is a command that can be run from within Terminal that will basically "reboot" the user's settings without having to log out.
I think it had something to do with launchctl or launchd or another one of the launch-related utilities.
Anyone know what this command is?
