Open Files from Command Line on OS X
I'm as much of a fan of application UIs as anyone else but I'm finding myself working more and more from the command line lately. Much of that is becoming obsessed with media manipulation but I'm forcing myself to use less UIs so that I can understand what's under the hood of my favorite utilities.
One common case for running any app is opening an existing file, like an HTML file in a browser or a document in Pages. To open a file on Mac OS X from the command line, type the following:
open portrait.png
The above does not specify an app to open the given file in -- the default app for that file type will be used. To open a file in a specific app, use the -a argument:
open -a /Applications/Firefox.app portrait.png
You can also open a URL directly from the command line:
open https://davidwalsh.name/
You'd expect opening a file from command line to be easy and I'm happy to confirm to you that it is.

![Face Detection with jQuery]()
I've always been intrigued by recognition software because I cannot imagine the logic that goes into all of the algorithms. Whether it's voice, face, or other types of detection, people look and sound so different, pictures are shot differently, and from different angles, I...
I was just wondering how to do this, thanks!
When you use
-a, you don’t need to write the path.…would do the same. :)
The
-ahandler is great when you want to open some program one doesn’t really know (eg remember) exactly where it is.Like:
// that one is in /System/Library/CoreServices
