title: How to open a window from mac terminal
body: <p>this is the first time I ask on stackoverflow because I can't find the answer anywhere. I use emacs to write all my code and I just switched from ubuntu to mac os. One problem has been bothering me: How could you open emacs window from mac terminal just like you would open firefox window from terminal on Linux system? I know the way it works for Linux system is that, whenever you type a command from terminal, the terminal search for the binary in you PATH and execute it. Is it the case for Mac that you can only open applicaiton in window form under "/Application" directory and all binaries opened from terminal are in non-window form? Big thanks!!</p>
