The ‘open’ command will do the same thing that double-clicking the app in the Finder would do, so if the app’s already open, it will simply bring that app to the front (and open a new document if there’s not already a window open). Executing the binary itself can lead to multiple instances of the same app being open. Note that the ‘open’ command is just a wrapper around APIs provided by the system, so in a Cocoa app, it would make more sense to use those directly instead of fork/execing a command-line program. You can either use the LaunchServices APIs found in /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Headers/LSOpen.h, or if you prefer a nice easy-to-use Objective-C wrapper, NSWorkspace has a decent number of openURL:, openFile:, and launchApplication: methods for you to choose from.
