runtime.exec

I have rsync command to be run in a java program...the problem i am facing is that rsync requires a password to be entered and i am not understanding how to pass this password to the rsync command to work? Andrei LED I was gonna post this code sample: Process rsyncProc = Runtime.exec ("rsync"); OutputStreanm rsyncStdIn = rsyncProv.getOutputStream (); rsyncStdIn.write ("password".getBytes ()); But Vineet Reynolds was ahead of me. As Vineet Reynolds pointed out using such approach will require an additional piece of code to detect when rsync requires a password. So using an external password

I have a Java program that executes Runtime.getRuntime().exec("ls -l"); many times, once for each directory in the system. My test system has more than 1,000 directories and Runtime.getRuntime().exec("ls -l"); seems to error out after 480 directories or so. The error message I'm getting is is "Error running exec(). Command: [ls, -l] Working Directory: null Environment: null". I'm guessing it's running out of some required system resources or is it? Is there any way to process all directories without erroring out? Relative comment from an answer: I should clarify that I was using Android SDK's

Can anyone make any suggestions about how best to use EasyMock to expect a call to Runtime.getRuntime().exec(xxx) ? I could move the call into a method in another class that implements an interface, but would rather not in an ideal world. interface RuntimeWrapper { ProcessWrapper execute(String command) throws IOException; } interface ProcessWrapper { int waitFor() throws InterruptedException; } I was wondering if anyone had any other suggestions? Your class shouldn't call Runtime.getRuntime() . it should expect a Runtime to be set as its dependency, and work with it. Then in your test you can

I have an issue when I'm using Runtime.exec with my Android device and just can't figure out why it happens... Here is an example of the tests I did : public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Runtime runtime = Runtime.getRuntime(); for(int i=0; i< 20; i++){ Log.d("TESTEXEC", "EXEC N°"+i+" : BEGIN"); try { Process process = runtime.exec("/system/bin/ps"); process.getErrorStream().close(); process.getOutputStream().close(); process.getInputStream().close(); process

I can use Runtime.exec() to execute shell commands like " getprop " and " ls system " and they work fine. However, when I use " echo $BOOTCLASSPATH ", " echo \\$BOOTCLASSPATH " or " echo HelloWorld ", it won't show it in stdout. The logcat shows: I/AndroidRuntime( 4453): VM exiting with result code -1. Here's my code: try { java.lang.Process proc = Runtime.getRuntime().exec("echo -e \\$BOOTCLASSPATH"); String line = null; InputStream stderr = proc.getErrorStream(); InputStreamReader esr = new InputStreamReader (stderr); BufferedReader ebr = new BufferedReader (esr); while ( (line = ebr

In the project I am working on, I need to execute a script that I have in a resources folder -- in the class path. I am simply testing the final script functionality, since I am on Windows, I needed a way to output a file to STDIN so I created a simple cat.jar program to clone unixs cat command. So when I do "java -jar cat.jar someFile.txt" it will output the file to stdout. I'm sure there are different ways of doing what I did. Anyways, I want to run that JAR from my main java program. I am doing Runtime.getRuntime().exec("java -jar C:/cat.jar C:/test.txt"); I've tried switching the forward
