How can I make the QuickTime updates not hang a CLI softwareupdate?

The QuickTime installer loves to throw up a dialog that asks for you to upgrade to a QuickTime Pro serial number. If you are installing via the command line this hangs the install process. There are a few ways around this.

1. Set the COMMAND_LINE_INSTALL shell variable to '1'. This will prevent the installer from asking interactive questions.

for bash:
export COMMAND_LINE_INSTALL=1

for tcsh:
setenv COMMAND_LINE_INSTALL 1

Since this is one of those things you would pretty much always want I simply add it to my .profile.

(Update! This first method seems to be broken under 10.3.5..)

2. You can open a second terminal session to the server and kill the QuickTime Installer process. Ugly, but it works.

3. You can purchase and install a QuickTime Pro license so that it won't ask during updates any more. :)
