Spaces in java execute path for OS X

Question

On OS X, I am trying to .exec something, but when a path contains a space, it doesn\'t work. I\'ve tried surrounding the path with quotes, escaping the space, and even usin

Answer 1

Paul's option works, but you still must escape the spaces like so:

Runtime.getRuntime().exec(new String[]{"open", "/folder\\ name/toast.sh"});

The thing that sucks about using a String array is that each param and its option must be in their own element. For instance you cannot do this:

Runtime.getRuntime().exec(new String[]{"executable", "-r -x 1", "/folder\\ name/somefile"});

But instead must specify it like so:

Runtime.getRuntime().exec(new String[]{"executable", "-r", "-x", "1", "/folder\\ name/somefile"});

There's a summary of this problem on Sun's forums... seems to be a pretty common issue not restricted to OS X.

The last post in the thread summarizes the proposed solution. In essence, use the form of Runtime.exec that takes a String[] array:

String[] args = new String[] { "open", "\"/folder name/toast.sh\"" }; 

or (the forum suggests this will work too)

String[] args = new String[] { "open", "folder name/toast.sh" };

Answer 3

Try this:

Runtime.getRuntime().exec("open /folder\\ name/toast.sh");

"\ " will just put a space in the string, but "\ " will put a "\ " in the string, which will be passed to the shell, and the shell will escape the space.

If that doesn't work, pass in the arguments as an array, one element for each argument. That way the shell doesn't get involved and you don't need bizarre escapes.

Runtime.getRuntime().exec(new String[]{"open", "/folder name/toast.sh"});
