How to execute dos command in Java program?

In Perl, it has System(command) to call dos command.
Does java have this thing?
or any other way to execute dos command in java program?
Because i must call javacto compile a file when the user inputed a java file name.

Look in the Runtime class, it is implemented using the Singleton design pattern so you have to use the static method getRuntime to get its only instance, on that instance you can invoke methods like
exec(String command) that will execute that command in a dos shell.

How to use runtime.exe to activate the native file coping commands

How to use runtime.exe to activate the native file coping commands.(It might include using process(), and such.. but how?

Why would you want to do this? It's harder than copying the file in Java (by reading the file and writing it to a new file) and you'll need to write new code each time you want to port your code to a new OS.

        String command = "ls";
        Process child = Runtime.getRuntime().exec(command);
        // Execute a command with an argument
        command = "ls /tmp";
        child = Runtime.getRuntime().exec(command);
    } catch (IOException e) {
    }With Arguments:
try {
        // Execute a command with an argument that contains a space
        String[] commands = new String[]{"grep", "hello world", "/tmp/f.txt"};
        commands = new String[]{"grep", "hello world", "c:\\Documents and Settings\\f.txt"};

Execute dos commands through java

Hi,
Im trying to execute dos commands through java like
          try {
               java.lang.Runtime.getRuntime().exec("cmd /c cls");
          }catch(IOException e){
               System.out.println(e.getMessage());
          }Not sure if its possible? however
open notepad would work
          try {
               java.lang.Runtime.getRuntime().exec("notepad");
          }catch(IOException e){
               System.out.println(e.getMessage());
          }Im trying to execute a cls commands to clear screen but without luck.

The question is, which shell do you want to clear?
I don't really know, but it could be that Runtime.exec executes its command in a new shell window...

How to use Runtime.getRuntime("command") in win?

I dont know how to use this method in win entironment, for example about file opertions, where there is some documents on detail about it?

Huh?
There is a method called Runtime.getRuntime(). It does not take any parameters. The javadocs describe it.
Is that what you are asking about?

Execute DOS command from java application

Hello,
I want to execute a DOS command (MOVE, in order to move an image from a folder to an other) from a java application. How can I do this?
Francesco

Yes I have tested it and it is working but only when executing a bacth file. For instance:
Runtime rt = Runtime.getRuntime();
try{
Process proc = rt.exec("move.bat");
}catch(Exception ex){
ex.printStackTrace();
}and the command in move.bat is:
move c:\\temp\\*.gif C:\\temp2
You don't have to use double slashes in batch files, only in Java. But anyway it is working both ways.
It is not working when you try to execute the command without the batch file:
Process proc = rt.exec("move c:\\temp\\*.gif C:\\temp2"); -> this will not work.
It should work. Try to execute another command to see what happens.

How to using the executable software in Java

I got a software named: pdf to text convertor; which can format the text interface from the pdf, for example, you need add the page number with a4 paper, then the convertor can change the pdf into text with page numbers. it is running on the doc, the command like: c:\pdfconvertor\xpdfrc.exe "c:\filename\name.pdf", after the text file will exist in the same directory with the pdf file.
so my problem is how to use java to call this DOS command to execute the program, and then java can read the text file, does some one give me some idea? better with simple java code!! Thanks very much! I will pay dollar for the solutions

You can use:
String[] cmd = {"c:\\pdfconvertor\\xpdfrc.exe", "c:\\filename\\name.pdf"};
Process p = Runtime.getRuntime().exec(cmd);Wait for the process to finish:
p.waitFor()and do your thing with the output file.
Note there are mechanisms for capturing the input and output of the subprocess; see java.lang.Process javadoc.

Execute DOS command in current window!

All:
Here is my code :
import java.io.*;
public class BuildScript {
public static void main ( String[] args ) {
String[] command = {"C:\\winnt\\system32\\cmd.exe", "cls"};
try {
Process process = Runtime.getRuntime().exec ( command );
process.waitFor();
} catch ( InterruptedException e ) {
e.printStackTrace();
System.exit(-1);
} catch ( IOException e ) {
e.printStackTrace();
System.exit(-1);
System.out.println ( "DONE!" );
I just want to exeute some simple DOS command from Java application. And then I run this code, it hangs there for ever. I comments out "process.waitFor()", then it print out the "DONE" however it seems that it just open another console and clear that one and exit. For the main console I start my code, nothing happened.
Can anyone help me out how to execute the dos command in current console window.
Thanks

Can anyone help me out how to execute the dos command in current console window.Sorry to say but there is no way to do that.
The best way to clear the screen is to print a few hundred newlines.
Trust me, this is a frequently asked question.

Execute DOS command inside java

I have a java program that reads each new user from an inputfile and writes that same user to an output file. The program works fine and is shown below:
import java.io.*;
public class FileStreamsTest {
public static void main(String[] args) {
try {
File inputFile = new File("newbousrs.txt");
File outputFile = new File("outagain.txt");
FileInputStream fis = new FileInputStream(inputFile);
FileOutputStream fos = new FileOutputStream(outputFile);
int c;
while ((c = fis.read()) != -1) {
fos.write(c);
fis.close();
fos.close();
} catch (FileNotFoundException e) {
System.err.println("FileStreamsTest: " + e);
} catch (IOException e) {
System.err.println("FileStreamsTest: " + e);
What I would like to do after each write is to execute a DOS command that looks something like this: supervsr.exe -USER username -PASS password -IMPORTUSERS importfile.txt
The DOS command above will add each user to the system I want to as the loop goes through each user record.
How do I execute the DOS command above inside java?

Tried what but still having a problem...here is my code:
import java.io.*;
public class ReadSource {
public static void main(String[] arguments) {
try {
FileReader file = new FileReader("newbousrs.txt");
                              //FileWriter letters = new FileWriter("outagain.txt");
                              //PrintWriter pw = new PrintWriter(new FileWriter("outagain.txt"));
BufferedReader buff = new BufferedReader(file);
                              Runtime rt = Runtime.getRuntime();
boolean eof = false;
while (!eof) {
String line = buff.readLine();
if (line == null)
eof = true;
else
System.out.println(line);
                                             Process proc = rt.exec("\\Blowfish\\droot\\Program Files\\Business Objects\\BusinessObjects 5.0\\supervsr.exe -USER xxxxx -PASS yyyy -IMPORTUSERS \\Blowfish\\droot\\accsp\\public\\newusers\\newbousrs.txt");
                                             //System.out.println(line.substring(4, 10));
                                             //System.out.println(line.substring(3,line.indexOf(',',3)));
buff.close();
} catch (IOException e) {
System.out.println("Error -- " + e.toString());
There error I get is this:

Execute Process Task :Executing DOS Command lines in Execute Process Task

Hi All,
I am trying to sftp files using Tectia Client from my local system. For that I have used the Execute Process Task in SSIS. First I open DOS command and try to instantiate the sftp3.exe.
Then I write down the below command
binary
open username@hostname
lcd C:\Test
cd <Destination Path name>
put test.txt
How to execute the command in execute process task ?
help is appreciated
Thanks

Hi ConnectDebz,
According to your description and script example, do you use WinSCP.exe to perform the SFTP files transfer? If so, you should set the Executable of the Execute Process Task to the path of the WinSCP.exe, save the script in a .txt file and set the Argument
of the Execute Process Task like “/script=C:\Temp\sftploader.txt” (without quotes).
