Running System Commands using Java

HI,
I am developing an application using java which requires some system commands to be run.For example i have to write a java function which can program the windows scheduler to run a particular executable at some time & another one to initiate an ftp.I however do not know how to execute the corresponding commands from java.Is there any way or some specific api(similar to the system command in c) that i can use to perform these operations.I am using j2sdk 1.4.0_01 on a win 98 machine to develop the application.

See [url http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html]java.lang.Runtime

hello,
thanks for replay
i am sorry the above code should be like this.(the above code is working fine)

Running unix command using java shows error

Hi All,
I am trying to run UNIX move command using Java exec method but its throwing error, unable to rename. Here below is the code i am trying to run to move all files from one directory to another directory. source and destination directory exists.
public class Demo
    public static void main(String args[])
        try
            Runtime rt = Runtime.getRuntime();
            Process proc = rt.exec("mv /home/demo1/* /home/demo2");
            int exitVal = proc.waitFor();
            System.out.println("Process exitValue: " + exitVal);
        } catch (Throwable t)
            t.printStackTrace();
}if i give "mv /home/demo1 /home/demo2" in exec method, its working, with * character its giving problem.
Please help me in resolving the problem.
Thank you

Characters like *, >, &, |, etc. are interpreted by the command shell--that is by the bash, zsh, etc. programs. When you execute a command with ProcessBuilder or Runtime.exec, you're not going through one of those shells, so their interpretation of those characters is not available.
In your code, the character * is being delivered directly to the mv command (which doesn't think * is anything special), as opposed to being turned into a list of files and directories as it would be when it's interpreted by the shell. The mv command doesn't know anything about the * character being special.
If you want to have those shell interpretations, you need to execute the command through a shell. One example is like so, but a) you'll want to read up on the methods in exec() that take arrays of String, and b) you'll want to read up on ProcessBuilder, and c) you'll need to check your shell's man pages to see the exact syntax and arguments.
runtime.exec("/bin/bash -c 'mv x/* y'");

How to run system commands from JAVA

Hi Friends,
How to run windows system commands from JAVA
Runtime r=Runtime.getRuntime();
r.exec("dir");
Throwing following Exception
CreateProcess :dir error=2
Thanks in advance
Hamsa

Hi ,
in Windows NT this is not possible, you can use the following :
Runtime r=Runtime.getRuntime();
StringBuffer sbuf = new StringBuffer();
String dir = new String();
java.lang.Process proc = r.exec("cmd /c dir");
InputStream is = proc.getInputStream();
int ch ;
while((ch=is.read() ) != -1)
sbuf.append((char)ch);
is.close();
dir = sbuf.toString();
System.out.println(dir );

Urgent!! running system command in java

i am trying to run system command(windows) in java. I am getting
exception as java.io.IOException: CreateProcess: c:\dir
Please Help.
Here is the code
import java.io.*;
public class RunCommand {
public static void main(String[] args) {
try
//run dir command
Process p = Runtime.getRuntime().exec("c:\\dir");
BufferedReader stdInput=new BufferedReader(new
InputStreamReader(p.getInputStream()));
BufferedReader stdError =new BufferedReader(new
InputStreamReader(p.getErrorStream()));
//read the output
System.out.println("here is the output:\n");
while((s=stdInput.readLine())!=null){
System.out.println(s);
System.out.println("here is the error if any");
while((s=stdError.readLine())!=null){
System.out.println(s);
System.exit(0);
}//end try
catch (IOException e)
System.out.println("exception Happened" );
e.printStackTrace();
System.exit(-1);

It works fine if you replaceProcess p = Runtime.getRuntime().exec("c:\\dir");withProcess p = Runtime.getRuntime().exec("cmd /c dir");And don't forget to define your s variable.

Run shell commands using java program

Hi guys,
I am trying to run shell commands like cd /something and ./command with arguments as follows, but getting an exception that ./command not found.Instead of changing directory using "cd" command I am passing directory as an argument in rt,exec().
String []cmd={"./command","arg1", "arg2", "arg3"};
File file= new File("/path");
try{
Runtime rt = Runtime.getRuntime();
Process proc = rt.exec(cmd,null,file);
proc.waitFor();
System.out.println(proc.exitValue())
BufferedReader buf = new BufferedReader(new InputStreamReader(proc.getInputStream()));
catch(Exception e)
{e.printStackTrace();
So can anyone please tell me what is wrong with this approach? or is there any better way to do this?
Thanks,
Hardik

What gives you the idea that the process to execute is called "./command"? If this is in Windows, it is "cmd.exe" for example.It does not have to be cmd.exe in Windows. Any executable or .bat file can be executed as long as one either specifies the full path or the executable is in a directory that is in the PATH.
On *nix the file has to have the executable bit set and one either specifies the full path or the executable must be in a directory that is in the PATH . If the executable is a script then if there is a hash-bang (#!) at the start of the first line then the rest of the line is taken as the interpreter to use. For example #!/bin/bash or #!/usr/bin/perl .
One both window and *nix one can exec() an interpreter directly and then pass the commands into the process stdin. The advantage of doing this is that one can change the environment in one line and it remains in effect for subsequent line. A simple example of this for bash on Linux is
import java.io.OutputStreamWriter;
import java.io.Writer;
public class ExecInputThroughStdin
    public static void main(String args[]) throws Exception
        final Process process = Runtime.getRuntime().exec("bash");
        new Thread(new PipeInputStreamToOutputStreamRunnable(process.getErrorStream(), System.err)).start();
        new Thread(new PipeInputStreamToOutputStreamRunnable(process.getInputStream(), System.out)).start();
        final Writer stdin = new OutputStreamWriter(process.getOutputStream());
        stdin.write("xemacs&\n");
        stdin.write("cd ~/work\n");
        stdin.write("dir\n");
        stdin.write("ls\n");
        stdin.write("gobbldygook\n"); // Forces output to stderr
        stdin.write("echo $PATH\n");
        stdin.write("pwd\n");
        stdin.write("df -k\n");
        stdin.write("ifconfig\n");
        stdin.write("echo $CWD\n");
        stdin.write("dir\n");
        stdin.write("cd ~/work/jlib\n");
        stdin.write("dir\n");
        stdin.write("cat /etc/bash.bashrc\n");
        stdin.close();
        final int exitVal = process.waitFor();
        System.out.println("Exit value: " + exitVal);
}One can use the same approach with Windows using cmd.exe but then one must be aware of the syntactic differences between commands running in .bat file and command run from the command line. Reading 'help cmd' s essential here.
The class PipeInputStreamToOutputStreamRunnable in the above example just copies an InputStream to an OutputStream and I use
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
public class PipeInputStreamToOutputStreamRunnable implements Runnable
    public PipeInputStreamToOutputStreamRunnable(InputStream is, OutputStream os)
        is_ = is;
        os_ = os;
    public void run()
        try
            final byte[] buffer = new byte[1024];
            for (int count = 0; (count = is_.read(buffer)) >= 0;)
                os_.write(buffer, 0, count);
        } catch (IOException e)
            e.printStackTrace();
    private final InputStream is_;
    private final OutputStream os_;
}

Running System commands using Runtime.exec()

I'm trying to run an example from "The Java Programming Language" book by Arnold, Gosling and Holmes. I'm trying to run a system level command and get the results. The code looks like:
public static String[] runCommand(String cmd) {
String[] outputData= null;
String[] cmdArray = {"/usr/bin/ls", "-l", "/tmp"};
try {
Process child = Runtime.getRuntime().exec(cmdArray);
InputStream in = child.getInputStream();
InputStreamReader reader = new InputStreamReader(output);
BufferedReader = new BufferedReader(reader);
// read the commands output
int counter = 0;
String line;
while ((line = input.readLine()) != null)
outputData[counter++]= line;
if (child.waitFor() != 0){ // error when it's not 0
System.out.println("Couldn't run the command.");
System.out.println("It produced the following error message : " + child.exitValue());
outputData = null;
} catch (Exception e){
System.out.println("It got here!");
System.out.println("It produced the following error message : " + e.getMessage());
outputData = null;
return outputData;
It gets to the while line, trys to run the input.readLine() and kicks out the exception that looks like:
It got here!
It produced the following error message : null
I know it gets to the input.readLine() because I had a whole lot more try blocks in there, but for simplicity left it out (so it look like the code in the book, which I tried originally). When I run the same command from the command line (on our Sun Solaris 2.8 system) I get results back. I'm not sure what I'm doing wrong. Any help would be greatly appreciated. Thanks.

Hi, duffymo, hope you can help me. Consider this servlet code:
String theCommand = "csh /export/home/gls03/sasstuff/runsas.csh /export/home/g
ls03/sasstuff/gary2.sas";
//Create a parent Process for the sas program subprocess:
Process p = rt.exec(theCommand);
System.out.println("after call to rt.exec(theCommand)");
Here is the runsas.csh script:
#!/bin/csh
setenv LD_LIBRARY_PATH /opt/sybase/lib:/usr/lib:/usr/openwin/lib:/opt/SUNWspro/S
C2.0.1
setenv SASROOT /usr/local/CDC/SAS_8.2
setenv XKEYSYMDB /usr/local/CDC/SAS_8.2/X11/resource_files/XKeysymDB
$SASROOT/sas -sasuser /hpnpages/cgi-bin/applinks/hospcap/tmp $1
The execution never gets to the println statment, here is the error:

The command runs fine in unix.
I've also tried using these as arguments to exec:
String theCommand = "/bin/csh /export/home/gls03/sasstuff/runsas.csh /export/home/gls03/sasstuff/gary2.sas";
String[] theCommand = {"csh", "/export/home/gls03/sasstuff/runsas.csh", "/export/home/gls03/sasstuff/gary2.sas"};
These generate the same error. I'm thinking this is a sas-specific problem.
Thanks for any help. Gary

Running Dos Command using Java

How do i run a particular Dos command using a simple java class?

Search the forum. There are plenty of examples.

Problem in running system commands using Runtime()

hi,
i am trying to run the "dir" command in windows OS using Runtime(). But while
executing the program i am getting
java.io.IOException: CreateProcess: dir error=2 error. But if i replace the "dir" command by "notepad" command its working fine. below is the source code.
class testing
public static void main(String args[])
     try{
Runtime rt=Runtime.getRuntime();
Process p=rt.exec("dir"); //Generating Errors
//Process p=rt.exec("notepad"); //Working Fine
     }catch(Exception e){System.out.println(e);}
}plzz help me out.
thanx

thats fine its working. i made two changes. First i used an array to send the
arguments. if we directly use "cmd.exe /c dir" then its converting "/C" to "\C" thus
producing the error. so i used
Runtime rt=Runtime.getRuntime();
String args1[]={"cmd.exe","/C","dir"};
Process p=rt.exec(args1);But then i got no error no output. From other forums i came to know about capturing the data using input streams and i included the following code.
BufferedReader Resultset = new BufferedReader
     (new InputStreamReader(p.getInputStream()));
String line;
while ((line = Resultset.readLine()) != null)
     {          System.out.println(line);          }Now its working fine. Thanx for ur help.

I have tried it sofar thru Runtime.getRuntime().exec("execute.bat");
but it is not working.anybody knows about how to run the system commands thru java please give me the code.

I've seen other posts with this questions, and answers. Unfortunately I didn't pay much attention. But the basic idea is to exec command.com and pass the specifc batch or command as an argument.

Running ls command from Java stroed procedure no output

Hi ,
I am trying to run ls command from java stored procedure in oracle
Process p = Runtime.getRuntime().exec("ls");
BufferedReader stdInput = new BufferedReader(new
InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new
InputStreamReader(p.getErrorStream()));
// read the output from the command
System.out.println("output of the command run:\n");
while ((s = stdInput.readLine()) != null) {
System.out.println(s);
from java stored procedure in oracle.
i get output of println statments but it does not go into while loop to print from stdInput.
Result of running Java stored procedure is -
output of the command run:
Call completed.
when i run the program on client side it works fine.
Has anybody tried this from java stroed procedure.
Thanks,
Jag

Jag,
Actually, the question of whether it works for me seems to depend on the version of the OS (or Oracle). On RedHat Linux (Oracle 8.1.6) it didn't work at all, but on Solaris (Oracle 9.0.2) it did. Here's the output from that run:
SQL> /
output of the command run:
init.ora
initDBPart9i.DBPSun01.ora
initdw.ora
lkDBPART9I
orapw
orapwDBPart9i
spfileDBPart9i.ora
Done
PL/SQL procedure successfully completed.
But, I did need to change a line of your code to this:
Process p = Runtime.getRuntime().exec("/usr/bin/ls");
your original was:
Process p = Runtime.getRuntime().exec("ls");
You might consider, if possible, use of some of the Java File classes instead of ls, as this might make things more predictable for you. There were some examples in oramag.com a few months ago, but they were pretty simple (you might not need them).
Hope this helps,

Spanish characters getting garbled while executing command using Java code

Hi,
I try to execute a command using java code. output of the command contains spanish characters. Few of these characters getting garbled after the command execution.
Runtime r = Runtime.getRuntime();
          Process p = null;
String pgm="ipconfig /all";
          try
                    p = r.exec(pgm);
BufferedReader br=new BufferedReader(new InputStreamReader

while((val = br.readLine()) != null){ System.out.println(val);
          catch (Exception e)
                    return (null);
I tried to run the code using -Duser.language=es -Duser.region=ES -Dfile.encoding=Cp850, but this did nt help. I could see the outputs properly in command prompt,
If i redirect the output to a text file , it is getting garbled,
Please let me know to solve this issue.
