• The program is actually installed in the TWAIN directory tree on the Mac. (Library/Image Capture/TWAIN Data Sources) When I log on to a 'regular' admin level account (that is, the account does have administrative privileges) the program will not run; it thinks for a bit, and then says 'please run as administrator'.

Calling Command-Line Tools

Feb 06, 2013 Launching OS X GUI Apps as root user. The command syntax is as follows: sudo /Path/To/Application/ApplicationName.app/Path/To/Executable. In most cases, that will be applications stored in the /Applications/ directory, and the executable is almost always stored in Package/Contents/MacOS/ as whatever the applications name is.

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.

Note

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

Executing Commands

Mac Os X Run App From Command Line Linux

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

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.

APPLESCRIPT

Mac Os Command Line Tools

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

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.

APPLESCRIPT

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. *)
