Terminal command to quit Google's "Backup and Sync"? Is there a terminal command I can use to quit Google's "Backup and Sync" software?  I am writing a Bash script to set the machine up for maximum battery life and I would like to shutdown all non-essential software that I usually have running in the background such as Backup and Sync.  I tried the usual suspects (osascript -e 'tell app "Backup and Sync from Google" to quit' AND killall 'Backup and Sync from Google') without success.
Weird, just tried killall "Backup and Sync from Google" and it failed.

Try killall Backup\ and\ Sync, that worked for me for some reason. Adding \ from seems to break things.
