How to set working directory with ProcessBuilder
51,654
You are trying to execute /home and it is not an executable file. The constructor argument of the process builder is the command to execute.
You want to set the working directory. You can that it via the directory method.
Here is a complete example:
Process p = null;
ProcessBuilder pb = new ProcessBuilder("do_foo.sh");
pb.directory(new File("/home"));
p = pb.start();

I am trying start a process in my home directory in ubuntu. I keep getting a permission denied exception and I have no idea why. Here is the code:
Process p = null; ProcessBuilder pb = new ProcessBuilder("/home"); p = pb.start();
Here is the exception:
Exception in thread "main" java.io.IOException: Cannot run program "/home": java.io.IOException: error=13, Permission denied at java.lang.ProcessBuilder.start(ProcessBuilder.java:475) at tester.Main.main(Main.java:30) Caused by: java.io.IOException: java.io.IOException: error=13, Permission denied at java.lang.UNIXProcess.<init>(UNIXProcess.java:164) at java.lang.ProcessImpl.start(ProcessImpl.java:81) at java.lang.ProcessBuilder.start(ProcessBuilder.java:468) ... 1 more Java Result: 1

Volokh over 4 yearsI had to use ProcessBuilder pb = new ProcessBuilder(new String[]{"sh","do_foo.sh"}); in order to make it work.
