无法运行程序“/Applications/Utilities/Terminal.app”：错误= 13，权限被拒绝

Question

I am currently experiencing substantial complications when running the code below:

package practice;

import java.io.IOException;

public class ProgramExecutor {

    public static void main (String [] args){
        try{
            Process p = Runtime.getRuntime().exec("/Applications/Utilities/Terminal.app");
        } catch (IOException e){
            e.printStackTrace();
        }
    }
}

It returns the following error message:

java.io.IOException: Cannot run program "/Applications/Utilities/Terminal.app": error=13, Permission denied
    at java.lang.ProcessBuilder.start(ProcessBuilder.java:1048)
    at java.lang.Runtime.exec(Runtime.java:620)

    at java.lang.ProcessBuilder.start(ProcessBuilder.java:1029)
    ... 4 more

How would I go about resolving it. It appears to be due to a permission issue on my Mac. I have changed the permissions in the Terminal using chmod command with little success. What else could it be? Is it possible to run Eclipse as a super user in order to access this file?

Answer 1

The path '/Applications/Utilities/Terminal.app' is the path to the Terminal application, which is a directory. The actual executable Terminal program path is:

/Applications/Utilities/Terminal.app/Contents/MacOS/Terminal

this is the path you need in the exec call.

Alternatively use the

open -n /Applications/Utilities/Terminal.app

command.

Answer 2

I was getting this error: java.io.IOException: Cannot run program "/filetransfer.pl": error=13, Permission denied

I resolved the issue giving the permission to the filetransfer.pl script file to execute. I use the terminal to execute the permission command. My problem is resolved.

chmod 777 filetransfer.pl
