If arguments is nil, an NSInvalid Argument Exception is raised. Discussion The NSTask object converts both path and the strings in arguments to appropriate C-style strings (using file System Representation ) before passing them to the task via argv. Run the project in the current directory (the -help argument in this example is passed to the application, since the blank -option is used): dotnet run -configuration Release - -help Restore dependencies and tools for the project in the current directory only showing minimal output and then run the project: (.NET Core SDK 2.0 and later.

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. But with OS X and its Darwin core, there's often an elegant integration between the two. In this how-to I'll show you how to launch an OS X app from the command line with the open command.
[Note: A little bit of prior UNIX experience will be helpful here.]
First off, I will admit this technique is fairly geeky. In my [Mac] OS X career, I've only used this trick a handful of times. However, it's so darn cool and charming that one just aches to use it at any opportunity. Uninstall software on mac el capitan.
Actually, upon reflection, there are some useful scenarios for this technique.
- 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.
- 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.
- 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 want to quickly run a utility with admin privileges without the restriction of the account you're logged into. See, for example, 'How to Find & Recover Missing Hard Drive Space.' In that case, you must bypass the open command and drill into the Package Contents to run the app with sudo and admin privileges. But I've digressed.
The Man Page
The terminal app is in the Utilities folder—which is found the Applications folder. Launch it now. The BSD UNIX command we'll be using is open. Below is the manual page ('man' for short), shown by typing:
I've printed most of the man page for the open command here for your perusal, but I'm not going to explore every argument. And feel free to jump right to the examples below to whet your appetite.
For this limited how-to, one interesting way to use the open command in this context is to use the [-a] option. Some other useful variations and arguments are in the examples below.
Typical Examples

Here are some short and sweet examples of the open command with the -a, -e, and -t arguments. They're easy to try. [If you don't have BBEdit installed, use any other favorite a text editor in /Applications.]
Open Doors
These are just a few of the cool things you can do on the command line with the open command. To keep things simple, I haven't delved into creating a search path or other Unix tricks like aliases. All that's been left for you to explore on your own.

Mac Open App With Arguments
Basically, a Mac application has a
.app
extension, but it’s not really a file — it’s a package. You can view the application’s contents by navigating to it in the Finder, right-clicking it and then choosing “Show Package Contents”.Mac Start App With Arguments Windows 10
The internal folder structure may vary between apps, but you can be sure that every Mac app will have a
Contents
folder with a MacOS
subfolder in it. Inside the MacOS
directory, there’s an extension-less file with the exact same name as the app itself. This file can be anything really, but in its simplest form it’s a shell script. As it turns out, this folder/file structure is all it takes to create a functional app!Enter appify
After this discovery, Thomas Aylott came up with a clever “appify” script that allows you to easily create Mac apps from shell scripts. The code looks like this:
Installing and using appify is pretty straightforward if you’re used to working with UNIX. (I’m not, so I had to figure this out.) Here’s how to install it:
- Save the script to a directory in your
PATH
and name itappify
(no extension). I chose to put it in/usr/local/bin
, which requires root privileges. - Fire up Terminal.app and enter
sudo chmod +x /usr/local/bin/appify
to make appify executable without root privileges.
After that, you can create apps based on any shell script simply by launching Terminal.app and entering something like this:
Mac Run App With Parameters
Obviously, this would create a stand-alone application named
Your App Name.app
that executes the your-shell-script.sh
script.After that, you can very easily add a custom icon to the app if you want to.
Adding a custom app icon
- Create an
.icns
file or a 512×512 PNG image with the icon you want, and copy it to the clipboard (⌘ + C). (Alternatively, copy it from an existing app as described in steps 2 and 3.) - Right-click the
.app
file of which you want to change the icon and select “Get Info” (or select the file and press ⌘ + I). - Select the app icon in the top left corner by clicking it once. It will get a subtle blue outline if you did it right.
- Now hit ⌘ + V (paste) to overwrite the default icon with the new one.
Note that this will work for any file or folder, not just
.app
files.Examples
Chrome/Chromium bootstrappers
Mac Open Application With Arguments
I like to run Chrome/Chromium with some command-line switches or flags enabled. On Windows, you can create a shortcut and set the parameters you want in its properties; on a Mac, you’ll need to launch it from the command line every time. Well, not anymore :)
The
&
at the end is not a typo; it is there to make sure Chromium is launched in a separate thread. Without the &
, Chromium would exit as soon as you quit Terminal.app.Launch a local web server from a directory
Say you’re working on a project and you want to debug it from a web server. The following shell script will use Python to launch a local web server from a specific directory and open the index page in your default browser of choice. After appifying it, you won’t even need to open the terminal for it anymore.
More?
Needless to say, the possibilities are endless. Just to give another example, you could very easily create an app that minifies all JavaScript and CSS files in a specific folder. Got any nice ideas? Let me know by leaving a comment!
