macOS Running a shell script at application launch

[051r15]

Hi forums, this is my first post! Im trying to run this script automatically when I launch terminal :

/System/Library/Frameworks/ScreenSaver.framework/Resources/ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine -background

it's a matrix digital rain screensaver I'd like to run in the background when terminal is launched, purely to show off. Can this be done in automator? If so, how would I go about doing that? I've looked around google, and not found anything useful.

Thanks in advance for any help! I will try and return the favor sometime.

One possible way:

1. Terminal | Preferences
2. Settings
3. Select whichever is the default settings
4. Shell
5. Run command
6. Paste your command then put a space followed by a &
7. Run inside shell

Then next time a Terminal window is opened the command will run in the (process) background.

Right on! Many thanks! The effect is cold-blooded . So does the "&" at the end tell the application to stop the script upon quitting? That's the effect I was going for, hadn't yet found the right command... Again, thanks a million!

No the & tells it to detach the task from the console and let it run in the background. http://en.wikipedia.org/wiki/Ampersand#Unix_shells Closing the process that launched it may have a side effect of killing the background job too, but that's not what the & is meant for.

Okay, here's the full command, along with a screenshot of the screensaver and color of terminal at once. Quite the effect, especially with the voice.

/System/Library/Frameworks/ScreenSaver.framework/Resources/ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine -background & say -v zarvox nooobs sayonara all your base are belong to us ich nii saan shi destroy

Hillarious!

Thanks for the link and clarification on the "&". I'm trying to seriously beef up the command line skills.
