Using this link, was able to use the stated CL to create a bootable OS X Yosemite boot / install USB stick
http://arstechnica.com/apple/2014/10/how-to-make-your-own-bootable-os-x-10-10-yosemite-usb-install-drive/
Then I said, this should be easily interactively scriptable, because let's say one's "Install OS X Yosemite" installer is in some other place than /Applications.
So I set out to make an interactive script to read an input path for source "Install OS X Yosemite" and the source of the USB Untitled drive.
Below is the terminal command line:
sudo /Applications/Install OS X Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install OS X Yosemite.app --nointeraction
My script keeps failing. Any ideas / direction, greatly appreciated.
thx
John
