Switch Applications From The Command Line With Apple's osascript
You can open and/or swith to an application from the command line using Apple's `osascript` tool to run either javascript or apple script.
The javascript looks like this:
Code
osascript -l JavaScript -e "Application('Sublime Text').activate()"
And the apple script version looks like this:
Code
osascript -e 'tell application "Sublime Text"' -e 'activate' -e 'end tell'
In some cases, you'll need to use the full path to the app
