It's a source that I made because I wanted to copy the directory, but I don't think there's an error or a mistake, but in conclusion, the file is not copied. Just in case I typed it wrong, I copied and copied the command part and executed it at the terminal, but it works well at the terminal...
java
String test_cmd[] = new String[] {"test.sh", "1", "test"};
ProcessBuilder test_pb = new ProcessBuilder(test_cmd);
Process test_p = test_pb.start();
int signal = test_p.waitFor();
When performing a Java terminal command, try separating it into a string array as shown above, not one string. You can separate them by spacing.
I looked it up when I was working on it, and I saw that it doesn't work properly if you use one string. It didn't work out in real life, so I used it as a string arrangement.
If that doesn't work, check the output using getInputStream() or getErrorStream() in Process after the waitFor() call.
There was a problem that I couldn't recognize the | in the command, and it didn't work as I thought.
