Add App To Mac Using Terminal Shell Script

  1. MacOS shell command to create a new Terminal Window. Of course, you can easily create a new Terminal window from the ‘Shell’ menu or by using the ⌘N (or ⌘T) keyboard shortcut. But in some cases, it can be more useful to use a shell command. New windows created with the keyboard shortcut or from the menu will always have the home.
  2. Ok, just for (nerd) fun, here’s a Bash shell script that will output a Matrix-ish display in Terminal. I have no idea if it works outside of BSD on OS X, but it has a chance. There’s a much better version of this effect written in C called “cmatrix” that you can install via Homebrew.

Calling Command-Line Tools

In AppleScript, the do shell script command is used to execute command-line tools. This command is implemented by the Standard Additions scripting addition included with OS X.

In this post, we show you some of the most interesting ways you can customize your Mac’s Terminal windows. Related: How to Open Any Folder from the Mac Terminal. Tweaking the Terminal Theme. Terminal has the built-in ability to theme up your shell windows, although you may not notice at first glance.

Note

The Terminal app in /Applications/Utilities/ is scriptable and provides another way to execute command-line tools from scripts.

Executing Commands

The direct parameter of the do shell script command is a string containing the shell code you want to execute, as demonstrated in Listing 39-1, which simply lists a directory.

APPLESCRIPT

Listing 39-1AppleScript: Executing a simple shell command that lists the contents of a directory
  1. do shell script 'ls /Applications/'
  2. (*
  3. --> Result:
  4. 'App Store.app
  5. Automator.app
  6. Calculator.app
  7. Calendar.app
  8. ...'
  9. *)

Since the direct parameter of do shell script is a string, you can concatenate it with other strings at run time. Listing 39-2, for example, concatenates a shell command to a previously defined parameter value.

Listing 39-2AppleScript: Concatenating a command with a value
  1. set theHostName to 'www.apple.com'
  2. do shell script 'ping -c1 ' & theHostName

Quoting Strings

The shell uses space characters to separate parameters and gives special meaning to certain punctuation marks, such as $, (, ), and *. To ensure that strings are treated as expected—for example, spaces aren’t seen as delimiters—it’s best to wrap strings in quotes. This process is known as quoting. If your string contains quotes, they must also be escaped (preceded by a / character) so they are interpreted as part of the string. Listing 39-3 shows an example of an error occurring as a result of a parameter that contains a space.

APPLESCRIPT

Listing 39-3AppleScript: An error resulting from a string containing a space
  1. set thePath to '/Library/Application Support/'
  2. do shell script 'ls ' & thePath
  3. --> Result: error 'ls: /Library/Application: No such file or directoryrls: Support: No such file or directory' number 1

The easiest way to quote a string is to use the quoted form property of the text class, as demonstrated in Listing 39-4. This property returns the string in a form that’s safe from further interpretation by the shell, regardless of its contents.

Listing 39-4AppleScript: Quoting a string to prevent errors
  1. set thePath to quoted form of '/Library/Application Support/'
  2. --> Result: '/Library/Application Support/'
  3. do shell script 'ls ' & thePath
  4. (*
  5. --> Result:
  6. 'App Store
  7. Apple
  8. ...
  9. '
  10. *)
