如何指定用于打开Mac OSX的Java System.exec（）文档的命令行？

Question

I am helping a colleague set up some GUI programming tools I have written in Java.

I need to "open", "start" or "launch" a document using Java System.exec(). For example, I want to open some text file in the default editor, possibly positioned at line 20, column 50. Or I want to start the default browser and display a particular HTML page.

What's the right way to do this?

Answer 1

You can use Desktop.open() which handles exactly that in an OS-independent manner.
So you do not need to mess around with Runtime.exec()

Answer 2

Try the "open" command, which opens a file (or URL or directory) just as if you had double-clicked on it, eg:

$ open http://slashdot.org # Opens in your web browser
$ open $HOME/foo.txt # Opens in your text editor
$ open $HOME # Opens in the Finder

I have verified that you can use that command with Runtime.exec() .
