Re: Environment variables available only from Cocoa apps

Hi all,

I have a postinstall executable as part of an installer. The installer can be launched in one of three ways:
- manually (ie. user launching installer by double clicking)
- as part of custom installer built by Assistant-like app
- using Apple Remote Desktop


I'd like to distinguish how it was launched, and behave slightly differently when the Installer is launched manually. As it appears, the postinstall is separate process from the Installer and I haven't found a way to indicate in the postinstall that the Installer is launched manually by user (instead of via ARD).

I'm thinking perhaps there is an environment variable that is available and can be checked only within Cocoa apps under Tiger and up. Does anyone know if such thing exists? Any help is appreciated. I am cross-posting to Cocoa-dev in the hope that somebody may have a solution.

There is one:

COMMAND_LINE_INSTALL

It can also be accessed from JavaScript.
