You can use java.lang.Runtime.exec to run simple code. This gives you back a Process and you can read its standard output directly without having to temporarily store the output on disk. For example, here’s a complete program that will showcase how to do it: import java.io.BufferedReader; import java.io.InputStreamReader; public class testprog { public static void … Read more
You need to use ProcessBuilder to redirect. ProcessBuilder builder = new ProcessBuilder(“sh”, “somescript.sh”); builder.redirectOutput(new File(“out.txt”)); builder.redirectError(new File(“out.txt”)); Process p = builder.start(); // may throw IOException
borrowed this shamely from here Process process = new ProcessBuilder(“C:\\PathToExe\\MyExe.exe”,”param1″,”param2″).start(); InputStream is = process.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader br = new BufferedReader(isr); String line; System.out.printf(“Output of running %s is:”, Arrays.toString(args)); while ((line = br.readLine()) != null) { System.out.println(line); } More information here Other issues on how to pass commands here and here
See if this works (sorry can’t test it right now) Runtime.getRuntime().exec(new String[]{“php”,”/var/www/script.php”, “-m”, “2”});
There are many reasons that waitFor() doesn’t return. But it usually boils down to the fact that the executed command doesn’t quit. This, again, can have many reasons. One common reason is that the process produces some output and you don’t read from the appropriate streams. This means that the process is blocked as soon … Read more
The various overloads of Runtime.getRuntime().exec(…) take either an array of strings or a single string. The single-string overloads of exec() will tokenise the string into an array of arguments, before passing the string array onto one of the exec() overloads that takes a string array. The ProcessBuilder constructors, on the other hand, only take a … Read more
Runtime rt = Runtime.getRuntime(); Process pr = rt.exec(“java -jar map.jar time.rel test.txt debug”); http://docs.oracle.com/javase/7/docs/api/java/lang/Runtime.html
Write a script, and execute the script instead of separate commands. Pipe is a part of the shell, so you can also do something like this: String[] cmd = { “/bin/sh”, “-c”, “ls /etc | grep release” }; Process p = Runtime.getRuntime().exec(cmd);
Batch files are not an executable. They need an application to run them (i.e. cmd). On UNIX, the script file has shebang (#!) at the start of a file to specify the program that executes it. Double-clicking in Windows is performed by Windows Explorer. CreateProcess does not know anything about that. Runtime. getRuntime(). exec(“cmd /c … Read more
