W Causes open to wait until the applications it opens (or that were already open) have exited. Saved persistent state is lost, except for Untitled documents. F Opens the application "fresh," that is, without restoring windows. Also useful for piping output to open and having it open in the default text editor. End input by sending EOF character (type Control-D). f Reads input from standard input and opens the results in the default text editor. t Causes the file to be opened with the default text editor, as determined via LaunchServices

e Causes the file to be opened with /Applications/TextEdit Specifies the bundle identifier for the application to use when opening the file Specifies the application to use for opening the file

Opened applications inherit environment variables just as if you had launched the application directly through its full path. For example, the following command would open all Word files in the current working directory:

You can specify one or more file names (or pathnames), which are interpreted relative to the shell or Terminal window's current working directory. If the file is in the form of a URL, the file will be opened as a URL. If no application name is specified, the default application as determined via LaunchServices is used to open the specified files. The open command opens a file (or a directory or URL), just as if you had double-clicked the file's icon. Some other useful variations and arguments are in the examples below.

You want to quickly run a utility with admin privileges without the restriction of the account you're logged into.

You're writing, say, a Perl or Python script, for another user and, at some point in the script, you'd like to launch a GUI app that carries the workflow forward.

You're a UNIX professional, live and breathe the command line, but you'd rather use a GUI text editor for coding instead of the raw and ugly vi or Emacs editors.

The Finder acts up, a terminal window is already open, and you'd like to be able to launch a GUI app that might help you diagnose the problem.

However, it's so darn cool and charming that one just aches to use it at any opportunity.Īctually, upon reflection, there are some useful scenarios for this technique. In my OS X career, I've only used this trick a handful of times. In this how-to I'll show you how to launch an OS X app from the command line with the open command.įirst off, I will admit this technique is fairly geeky. But with OS X and its Darwin core, there's often an elegant integration between the two.

In some flavors of Unix, you feel as if you've been cast into an alternate universe when you open a terminal window and work on the command line.
