Question

I’m using this code to make my Java program open a (visible) CMD window:

try {             String line;             Process p = Runtime.getRuntime().exec('cmd /C start \'Render\' \'' + myPath + '\\punchRender.cmd\'');              BufferedReader input =                     new BufferedReader(new InputStreamReader(p.getInputStream()));             while ((line = input.readLine()) != null) {             System.out.println(line);             jLabel7.setText(line);              }             input.close();         } catch (Exception err) {             err.printStackTrace();         } 

and I’ve been trying to do the same thing with the OSX terminal, this is where I’m at right now:

  try {             String line;             Process p = Runtime.getRuntime().exec('sh ' + myPath + '/punchRender.sh');              BufferedReader input =                     new BufferedReader(new InputStreamReader(p.getInputStream()));             while ((line = input.readLine()) != null) {             System.out.println(line);             jLabel7.setText(line);              }             input.close();         } catch (Exception err) {             err.printStackTrace();         } 

So far, no luck 🙁 Any suggestions? The .sh file isn’t even running…

I would just make sure your shell script has the execute bits on and just pass in the shell script file name.

Process p = Runtime.getRuntime().exec(myPath + '/punchRender.sh')

Edit:

I don’t know Java specifically if there is anyway to set file permissions for Unix/Linux with it to set the eXecute bit or how to escape quotes. But It would be something like this:

Process chmod = Runtime.getRuntime().exec('chmod u+x \'' + myPath + '/punchRenderer.sh\'')
