Problem in executing a unix command through java

hi
i'm trying to execute unix command through java
simple shell command like "ls -l >test " but i'm not able to see the result.
there are no error messages.
Code is:
import java.lang.Runtime.*;
class ExecDemo
     public static void main(String[] args)
          Runtime r=Runtime.getRuntime();
          Process p=null;
          try
               p=r.exec("ls -l > test");
          catch (Exception e)
               System.out.println("Error executing nedit.");
}can anyone help please.

get the the inputStream of the runtime object after executing the command.
now use the readLine() function until it becomes null.
egs: with reference to ur code.
InputStream is=p.getInputStream()
while(is!=null)
String s=is.readLine();
if the command don't execute try giving the full path also like /sbin/ls -l

  • GETTING THE OUPUT OF UNIX COMMAND THROUGH JAVA

    Hi Guyz...
    Please help me in the below code...
    My intention is to print the output of Unix command through a java program.
    The Java program resides in the Unix Server only.
    I have written the below java code , but its not returning any values....
    String s1= "ls -lt $APPL_TOP/patch/115/odf/jtfgh.odf";
    Runtime r = Runtime.getRuntime();
    Process p= r.exec(s1);
    StringBuffer ret=new StringBuffer();
    InputStream in = p.getInputStream();
    int c;     
    while ((c = in.read()) != -1)
    {                  ret.append((char)c);       
    }     in.close();
    out.println("OTUPUT : "+ ret.toString());
    Can you please help me in this by debugging the existing code or giving me the exact code??
    IT IS URGENT FOR MY PROJECT!!!!!!!!!!!!!!!!!!!!!!!!!!!
    PLEASE HELP ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    Since you are expecting the shell to expand the environment variable you need to use
    String[] s1= {"sh","-c","ls -lt $APPL_TOP/patch/115/odf/jtfgh.odf"};
    Also, you should read, digest and implement the recommendations of

    P.S Your urgency is not my problem and SHOUTING IS CONSIDERED VERY RUDE!

  • How to execute a Unix Command in java

    Hi, Iam trying to execute a unix command on Sun Solaris by passing that command to a java program. How can I achieve this?
    Thanks in advance.

    Have a look at the javadoc around the Runtime.exec() method. If the command is a shell command then you might have to execute a shell as well as the command.
    For example, if you wanted to run a unix command 'ls -l > output.txt' the you might have to pass the following string into the exec() method,
    "/bin/sh ls -l > output.txt'

    Since the pipe '|' is interpreted by the shell then you need the shell to invoke your command
            String[] command = {"sh","-c","find /tmp/reports1 -name " + "\"" + "*" + "\"" + " -mtime +" + strdaysback + " -print|xargs rm -r"};
            final Process process = Runtime.getRuntime().exec(command);
      You should also read http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html at least twice and implement the recommendation regarding stdout and stderr.
    P.S. Why are you not using Java to find and delete these files?

    1. This forum is for Swing-related issues only. This question should be posted to the "Java Programming" forum.
    2. Please enclose your sample code in code blocks; it's much easier to read that way. See here for how it's done: http://forum.java.sun.com/faq.jsp#messageformat
    3. Please provide more information, like what error messages you got and what OS you're running. For instance, if you're running WinXP, Win2k or NT4, your command processor should be "cmd.exe", not "command.com". When I made that change, your program worked for me.

  • Problems to execute "cd" DOS command from Java program

    Anyone try to exec command "cd.." or "cd directory", it doesn't have any action. No exceptions, just don't do anything.
    Runtime.getRuntime().exec("cd\\");
    Runtime.getRuntime().exec("cd hello");
    However, when I try the following, it is working fine. Any ideas???
    Runtime.getRuntime().exec("explorer");
    Runtime.getRuntime().exec("javac Test1.java");

    That's because cd is built into the command
    interpreter in Windows. Runtime.getRuntime().exec()
    can only be used to launch external programs. This
    article should get you going:And that's not the only reason why you can't do this.
    When you do
    Runtime.getRuntime().exec("cd c:\\");
    (or, heck, "cmd /c cd c:\\"): the new command that you spawn will cd to the destination specified, and then exit. The parent process (your java program, that is launching this command) won't go anywhere - the "cd" doesn't affect it.
    The only way to change your OS directory in Java is to invoke native code. And even then, the effects are undefined (in terms of how your CLASSPATH will be affected, etc.).

  • Execute unix commands from Java

    Hi,
    I have a client application running on windows. This client should connect to a unix server and check for the existence of a file and display the result as "File found/File not found". In order to connect from windows to the unix server, I used the sockets and the connection is successfully established. The second part is to check for the presence of the file in unix server. I searched in google.com and the option I found to execute a unix command from java is the "Runtime.exec()". Runtime.exec is considered as the less effective (not a favorable) one.
    Is there any other option available (other than the Runtime) to execute the unix command from java? Can you please let me know.
    Thanks a lot
    Aishu

    So, please let me know how I can execute the above unix commands without Runtime.exec()You have a client and a server.
    You want something to run on the server, not the client.
    That means that something must in fact being running on the server before the client does anything at all.
    For example telnet. Or a J2EE server application.
    So is something like that running?
    If not then there absolutely no way to do what you want, even with Runtime.exec().
    If yes then what you do depends on what is running. So Runtime.exec() would be pointless if a J2EE server was running.

  • Permission denied when I execute a unix command from within my java applet.

    Hi Gang,
    Forgive me if this is not the appropriate forum for this problem. I'm posting this problem on this forum since I got no answers on the other forum I posted on.
    I've written a simple java applet that runs a unix command and then displays some information. The applet compiles fine, and runs perfectly from the command line on my unix system.
    However, when I point a browser at the applet from my desktop PC I get the following error as taken from the java console:
    Exception in thread "AWT-EventQueue-2" java.security.AccessControlException: access denied (java.io.FilePermission <<ALL FILES>> execute)
    This is of course the first line in a long line of error messages. It appears that I am not able to execute a command on the unix system through my applet. I know the problem is with trying to execute a unix command since commenting it causes no error in the web browser. This is the command I'm using in java to execute the unix command:
    p = Runtime.getRuntime().exec("ps");
    Here's the html file on the unix system:
    <html>
    <head></head>
    <body>
    <appletcode=G.class height="250" width="400">
    Your browser does not support the applet tag.
    </applet>
    </body>
    </html>
    I won't list the java code since it is compiling and working on the command line. But, if you want to see it I'll provide it.
    I've done quite a bit of research on this and it seems that a great number of people have similar problems reading or executing files through java. I have yet to find a solution to this problem.
    Here are some details about my setup:
    Server:
    HP9000 running HP/UX 11.23

    If you have a solution I would be very grateful! This problem is keeping me from writing my application!

              }catch(IOException e){
                   System.out.println(e.getMessage());

              }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...
