Execute unix command in abap code

Hi, I have a request to execute a script command in a remote unix server, should i use 'call function ...destination'?
Thanks.
Legend.

Use like this :
data: begin of t_tabl occurs 0,
line(132),
end of t_tabl,
data: lc_command(100) type c.
Get all the file name falling under specified directory...
lc_command(3) = 'ls '.
lc_command+3(45) = p_dir. " Directory of file path
call 'SYSTEM' id 'COMMAND' field lc_command
id 'TAB' field t_tabl-sys.
Check any files exits in the directory.......................
if t_tabl[] is initial.
message e006 with 'No files exist in the specified directory ' p_dir.
endif.
Do not look for sy-subrc ,here sy-subrc will not work.
Thanks

UNIX command in ABAP code

Hi All,
I need to use unix command (MOVE) in ABAP code for transfering a file from one directory to another directory.
Can any one help with how to used unix commands in ABAP?
Thanks in advance.
Regards,
Hemendra

The recommended approach always used to be to use transaction SM69 to define a "soft" command name to the operating system command so that it could be configured to work across Windows, Unix etc. For example:
Command name OS Type OS command Parameters for operating system command
Z_FILE_MOVE SunOS Customer mv ? ?
You can then call function module SXPG_COMMAND_EXECUTE (quite well documented) to actually perform the command passing in the appropriate number of parameters.

3 I also created a shell script , but i get another message when i try to run sh ...
Please help to find out a way to make it work ..
Kunal

Hi kunal,
1. probably ur basis team might be able to help u.
2. even if we have authorisations thru sap
   to run external os command,
   the actual OS user on application server
   must have the right for it
   and access/write/read/modify
   for the files (provided thru the command)
   in question.
3. Due to this , the systems gives the message
   of SECURITY RISK.

Executing Unix Commands

Hi
I realise there is a Runtime class to help execute Unix commands from within Java code, but how would this work if the command required a password.
For example, were I to try to execute:
ssh -Y myserver.domain.com -u Myself -p
How would this work with supplying the password (which is prompted for after the command is sent to the shell)?
Thanks
Dave

from the ssh man page under "environment variables":     SSH_ASKPASS
              If ssh needs a passphrase, it will read the passphrase from the
              current terminal if it was run from a terminal. If ssh does not
              have a terminal associated with it but DISPLAY and SSH_ASKPASS
              are set, it will execute the program specified by SSH_ASKPASS
              and open an X11 window to read the passphrase. This is particu-
              larly useful when calling ssh from a .xsession or related
              script. (Note that on some machines it may be necessary to
              redirect the input from /dev/null to make this work.)

Use ODI OS command tool in the ODI package.
create an interface in ODI using LKM File to Sql and the output file generated with the csv file's row count as a source and the db table(where the count needs to be stored) as a target

Hi,
I'm new to JSP. I'm just curious whether is there a utility in Java that we can use to execute unix command?
thanks.

Hi,
You can try this,
import java.io.*;
public class test
public static void main(String args[]) {
try {
Process ps = Runtime.getRuntime().exec("ls -al");
BufferedReader br = new BufferedReader(new InputStreamReader(ps.getInputStream()));
BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(ps.getOutputStream()));
bw.write("1");
bw.flush();
String line;
while ((line = br.readLine()) != null) {
System.out.println(line);
br.close();
bw.close();
System.out.println(ps.exitValue());
catch(Exception e) {
System.out.println(e);
Hope that helps.

Executing UNIX command in Java

I am having problems executing a command in Java. Here's the code I have for executing:
Process p = Runtime.getRuntime().exec(cmd);
                                        BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
     while((display = input.readLine()) != null)
                         num_1 = Double.parseDouble(display);
                         percent = (num_1 * 100) / (50000000);
                    flip = 1;

A DESCRIPTION OF THE PROBLEM :
Unable to run signed applet with Netscape 4.79 and IE5.5
native JVM.
REGRESSION. Last worked in version 1.3.1
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.compile program and copy class files to a temp directory
2.sign the applet for Netscape as follows:
signtool -k aok -d \progra~1\netscape\users\viravan -Z
FIO.jar temp
3.sign the applet for Internet Explorer as follows:
cabarc -p n FileIO.cab FileIO*.class
setreg 1 true
makecert -sk aok -n "CN=aok" aok.cer
cert2spc aok.cer aok.spc
signcode -j javasign.dll -jp LOWX -spc aok.spc -k aok
FileIO.cab
Run the applet with the following HTML file:
<html><head><Title>Self-Signed Applet</Title>
<script>
document.layers ? parm=1 : parm=0;
</script>
<body>
This file I/O applet lets you read and write to the user's
local disk.<br>
<br>
<script>
document.writeln('<APPLET CODE = "FileIO" CODEBASE = "."
ARCHIVE = "FIO.jar" WIDTH = 10 HEIGHT = 10 NAME = "JSF">');

value="'+parm+'">');
document.writeln('<param name="cabbase"
value="FileIO.cab">');
document.writeln('</APPLET>');
</script>
</body>

Execute Unix command from Java program running on windows

Hello,
I need to write a java program that fetches file count in a particular unix machine directory. But java program will be running on windows machine.
The program should execute unix list command and fetch the output of that command.
Can anyone help me on this?
Thanks.

Hi there,
I had a similiar problem, though years ago. It was to have a java program execute any other. Lately, I've had to have a java program running on a unix machine execute a shell script. Entirely two different scenarios. I'm not sure what you will need for your app, but look into this:
Java Native Interface for executing C/C++ code.
C/C++ Code for launching the program you need to run.
java.lang.Runtime(?).exec(....)
With a combination of that stuff, you can make a launcher for any os that has Java running on it, and with Runtime, you can exec() pretty near any sort of unix shell or app command you'd like.
Good luck.

How to execute unix command in java or jsp

How does one execute unix commands from within an applet?

Greetings Folks,
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
Apache Web Server 2.0.35
Java 1.5
Desktop PC:
Win2K Pro
Internet Explorer 6
Java 1.6
If you have a solution I would be very grateful! This problem is keeping me from writing my application!
thanks!

Problem while executing unix command having \&\& symbol

Hi All,
Please check the below program while is not executing, when the unix command's having \&\& is used.
The following command copies the src folder to dest folder with out data loss ...
import java.io.*;
import java.util.*;
public class Sample
public static void main(String[] args)
     try {
          String ExCmd     =     "ssh [email protected] cd /u01/11510/devdb/9.2.0/slax \\&\\& /bin/tar cf - . | ssh [email protected] cd /d01/AppsTest/testappl2 \\&\\& /bin/tar -xf - > test.log";
          System.out.println("Command to execute : "+ExCmd);
          Process SshProc = (Runtime.getRuntime()).exec(ExCmd);
        // any error message?
          StreamReader errorStream = new StreamReader(SshProc.getErrorStream(), "DEBUG");
        // any output?
          StreamReader outputStream = new StreamReader(SshProc.getInputStream(), "OUTPUT");
        // kick them off
          errorStream.start();
          outputStream.start();
          int pp =SshProc.waitFor();
          System.out.println("command execution value: "+pp);
     }catch(Exception e) {
          e.printStackTrace();
class StreamReader extends Thread
    InputStream is;
    String type;
    StreamReader(InputStream is, String type)
        this.is = is;
        this.type = type;
    public void run()
        try
            InputStreamReader isr = new InputStreamReader(is);
            BufferedReader br = new BufferedReader(isr);
            String line=null;
            while ( (line = br.readLine()) != null) {
                System.out.println(type + ">" + line);
        } catch (IOException ioe)
            ioe.printStackTrace();
}When this is executed iam getting process value as "0".
But nothing is copying to target ..
So to resolve this i have created a script .. and passed arguments to that script and chaged command as follows :
String ExCmd = "sh /home/juser/movedir.sh [email protected] /u01/11510/devdb/9.2.0/slax /bin/tar [email protected] /d01/AppsTest/testappl2 /bin/tar /home/juser/test";
Then it is executing fine. But in my scenario iam restricted to use scripts.
So plz can any body have a solution for this.
Thanks, SN

Iam unable to execute command with &&, it's executing fine only from \&\& ... Can any body tell me how can we make below code as generic, depending on UNIX Shell environment?
String[] ExCmd     = {"sh", "-c", "ssh [email protected] cd /u01/11510/devdb/9.2.0/slax \\&\\& /bin/tar cf - . | ssh [email protected] cd /d01/AppsTest/testappl2 \\&\\& /bin/tar -xf - > test.log"};
Process SshProc = Runtime.getRuntime().exec(ExCmd);"sh" should be changed here depending on UNIX Environment, because previously i found that in some unix environment's "sh" is not working ..
So can any one help...
Thank in advance.

Execute Unix command on login

Hello, is it possible to execute a unix command on user login?
I want that every time a user login on a mac at my company, a unix command be executed.
Is this case, this is the command: defaults write com.apple.mail NSPreferredMailCharset "UTF-8"
thks in advance

{quote}Loginwindow Scripts
Another way to run applications at login time is to launch them using a custom shell script. Mac OS X provides two options for launching scripts when the user logs in. When creating your script file, keep the following in mind:
* The permissions for your script file should include execute privileges for the appropriate users.
* Scripts launched by loginwindow are run as root. Therefore, you should thoroughly test your scripts before deploying them to make sure they do not adversely affect the user's system.
*In your script, the variable $1 returns the short name of the user who is logging in.
* Other login actions wait until your hook finishes executing. Therefore, have your script do what it needs to do quickly and then exit. {quote}
I want the script to be run as the current user that does the login, and not as the root. I think that if its run as root, it changes nothing in the user. Does this root issue apllies to the Zerwas method?
It depends on how Zerwas was thinking you'd implement it. If you added it to each user's login items, it should run as the user. If you create a startup item to run it, it will run as root. I'm assuming Zerwas was suggesting the former because there would be no point in wrapping the shell script in an AppleScript if you are going to turn it into a startup item.
What you might be able to do - at least with the loginwindow script - would be to explicitly run the command as the user by making use of the fact that the user name is passed to the loginwindow script as $1. I've never used loginwindow scripts but it seems as though it should work.
Another possibility would be to use a LaunchAgent. These are really intended to manage background processes, though, and it seems an unnecessary use of resources to load one which will only ever be run at startup.
Can I ask why you wish to run the script every time a user logs in? Is the concern that the default will get set to something else and needs to be reset regularly?
