How to run piped Unix commands

Hi,
I'm trying to run piped Unix commands using Runtime.getRuntime().exec(...) but apparently the pipe symbol ("|") doesn't seem to work...
Here is basically what I'm trying to do: running "command1 | command2" where both "command1" and "command2" have dynamic values. I could create a shell script and execute it through Java but there has to be a cleaner way...
Can anyone help me with this?
Thanks,
Thierry

The | symbol for a pipe is understood by a shell, so it was right to point to this direction.
If you still have a problem, that might be because of another reason. What did happen, how exactly� did it not work? Did you take care of the stdin and stdout channels of the launched process?

How to run a unix command in java

Hi all,
I need to run a unix command in my standalone java application.my java program is in windows.Is it possible to run unix command on windows system.help me out.
I tried this
Process p = Runtime.getRuntime().exec("ps -ef");
            BufferedReader stdInput = new BufferedReader(new
                 InputStreamReader(p.getInputStream()));
            BufferedReader stdError = new BufferedReader(new
                 InputStreamReader(p.getErrorStream()));i get IO Exception -Create Process ps-ef error=2

If you want to run a command from java for a windows platform, you should check windows knows the command.
So, load up a DOS prompt and type ps -ef and see what happens.

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'

How to run several OS commands in file adapter ?

I can run one UNIX commands in a file receiver adapter. But could I run more than one command ? I tried to use a semicolon, but it doesn't work. Only 1st command is executed. (in UNIX, we can use semocolon to run several command in one command)

Hi
Create a batch file and in that put all the commands to be executed.
Mention this file in file adapter configuration ( CC ).
thanks

Having trouble in running a unix command and getting the output

Hi,
I am trying to run a unix command from within the java code. I am not able to make it work. I am enclosing the code and the error message that I am getting. Any help is highly appreciated.
import java.io.*;
public class RunCommand {
    public static void main(String args[]) {
        String s = null;
        try {
            Process p = Runtime.getRuntime().exec("cat UNIX_ASCII_TEXT_FILE | A_UNIX_PROGRAM -d");
            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("Here is the standard output of the command:\n");
            while ((s = stdInput.readLine()) != null) {
                System.out.println(s);
            // read any errors from the attempted command
            System.out.println("Here is the standard error of the command (if any):\n");
            while ((s = stdError.readLine()) != null) {
                System.out.println(s);
            System.exit(0);
        catch (IOException e) {
            System.out.println("exception happened - here's what I know: ");
            e.printStackTrace();
            System.exit(-1);
}The error message that I am getting is
Here is the standard output of the command:
SLu|%%$$=
Here is the standard error of the command (if any):
cat: cannot open |
cat: cannot open A_UNIX_PROGRAM
cat: cannot open -dLooks like the cat command is working and not the pipe command and the command after the pipe. But when I run the UNIX command from the command prompt I get the expected result.

You might read this article and see if its approach works.

How to run a openssl command from a java program

Hi All
Please suggest on how to run a openssl command from a java program.
I am using this
Runtime runtime = Runtime.getRuntime();
runtime.exec("openssl pkcs8 -inform der -nocrypt test.der result.pem");
This is suppose to take test.der as input and create result.pem.
There are no errors but the file result.pem isnt created.
Thanks in Advance

First off is that openssl command correct? Should it be this instead:
openssl pkcs8 -inform der -nocrypt -in test.der -out result.pem
Try out your openssl command within a command prompt so that you know that it works ok. I think the command line you specified waits on stdin (well it does for me).
After that.....
runtime.exec creates a Process object. If you do this:
Process openssl = runtime.exec("....")
then you can examine the return code from openssl to see the exit code - for instance if the input file does not exist then exit = 1. You can test for this with Java
Alternatively you could get the stderr from the process and look inside it - if it is 0 length then all is good, if it has some text in there then it has likely failed. You could then throw an exception and include the stderr output in the exception messgae. You may need to experiment with this, runnig it first when openssl is happy then running it again when openssl is upset.

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!

How to run a unix script from oracle warehouse Builder

Hi,
can any one share the information about, running the unix script or scripts using oracle warehouse builder.
Regards,
Ak

One way is define a workflow. Inside the workflow you put
1)an external process that "points to" the shell script and then
2)put the mapping
The external process must have the "COMMAND" parameter set to the name of the shell script. If the script has parameters you must put them in the "PARAMETERS LIST" separated by "?" (for example, ?par1?par2).
The path where OWB executes the external process I think is the ORACLE_HOME of the OWB.
f you don't use workflow, you can try with this more complex solution. I tried with 9i and OWB 9.2 and it's working well.
You create an autonomous procedure (within a package or not) :
CREATE PROCEDURE Extract_Email_List
DECLARE
PRAGMA AUTONOMOUS_TRANSACTION;
And use the sys.shell script that you need your dba/unix admin to install first of all, with a call like that.
sys.shell('sh ' || txt_dir_name || '/send_email_marketing.sh ' || txt_dir_name || ' ' || email_addr );
Then you import your procedure into OWB and use it in your mapping with the "pre-mapping" icon (you can set parameters for your proc with constants if you want).
To implement sys.shell, go to metalink and find "Note:168065.1" - "How to call a UNIX shell script from PL/SQL".
Once it's done once, it's not so bad. But I would still recommend the workflow approach also..
I hope this helps.

Run multiple unix commands from ODI procedure

I want to run a series of unix commands from ODI procedure. I dont want to use Unix shell scripts. (I know that works).I am just trying to place the contents of the shell scripts in ODI procedure with Operating system as technology. But I am unable to execute the proecedure.
For example below is a very small 3 line commands I would execute
filename="/var/test.txt"
ls -l $filename > /var/anotherfile.txt
chmod 777 $filename
I am not sure if there is any specific syntax that I have to follow for executing unix commands. Also I dont want to write a Jython and use os.system command as well.
Appreciate any help on this

First your original question... You can put more than one DOS command on a single line, simply separate each command with an ampersand (&). For example:
mkdir c:\abc & cd abc & dir*
Regarding your concerns about performance, well that would depend on exactly what you mean. Using CLIENT_HOST (or HOST on the server) simply opens a shell (DOS in this case) then passes your command to it. The performance of performing this action really isn't measurable. Basically you are just pressing a button and you should get a near immediate action. As for the performance of executing each command, that has nothing to do with Forms. Once the command is passed to the shell, the rest is a function of the shell and whatever command you passed.
Having said that, if you were to write something sloppy like a loop (in pl/sql) which called CLIENT_HOST lots of times repeatedly, then yes there would be a performance problem because the pushing of the button will cause an exchange to and from the server and each cycle in the loop will do the same.
So the answer to how performance is impacted will depend on what exactly you need to accomplish. If it is a single call to CLIENT_HOST, this should be fine.

Running a Unix command as "root" with NSTask

Hi,
I'm new to objective-C and Cocoa programming. I already know C and C++ (from classes I had in Uni.) but this one goes farther than what I've seen. Stricltly for learning purposes, I'd like to make a three button window where you click on a button and it launches /etc/daily and the two other cron tasks. But, in order to launch those commands, you need to use sudo. I guess wrapping a Unix command in a Cocoa application uses NSTask, but how do you get the app to run with root access?
Any help will be appreciated

How about launching Terminal with a script that calls

(Terminal) for the user's (which had better be an
admin user) password.
There should be no way to do this without requiring
admin authentication, preferably interactive. If
there were, it would be a privilege escalation
vulnerability in OS X...
That is exactly what I am looking for: I'd like my application the ask for administrator privileges before running the Unix scripts.

How to run multiple DOS commands from a single Webutil Client_Host session?

Hello all,
I have a requirement where I need to create an interface with SVN from Forms for basic checkin-checkout of files.
So, I've been trying to use webutil client_host to open a command line session and issue svn commands.
For svn, sometimes I need to give multiple commands like change to a particular directory and then run an svn command.
But client_host takes in only one command at a time and I'm unable to issue a series of DOS commands to perform
a particular task.
Is there a way to do this?
Pls suggest.
Regards,
Sam

How to Run Operating System Command Before/After Message Processing SAP PI

Hi,
We are trying to execute multiple commands via "Operating System Command Before/After Message Processing".
When we use single command say for example cp or mv (copy or move) the commands get executed fine.
eg: cp %F /var/opt/data/outbound/Test/Dummy.txt
/this works fine/
when we club commands together or try to redirect the outputs of commands, none of the commands get executed.
eg:
cp %F /var/opt/data/outbound/Test/Dummy.txt ; rm %F
or
wc -l %F > /var/opt/data/outbound/Test/Dummy.txt
Is it possible to execute multiple commands or redirect the output of commands without using a shell script? The PI server we are working on iis hosted on UNIX environment.

Hi Harleen,
try like this
cp %F /var/opt/data/outbound/Test/Dummy.txt ; rm %F
instead of semicolon try this
(1) &
command1 & command2
Execute Command1 and then execute Command2
(2) &&
command1 && command2
Runs the command2 only when command1 doesn't Complete successfully
(3) ||
command1 || command2
Runs the second command if the first command had an error
(4) ()
(command1 || command2) || (command3 & command4)
Defines the order in which commands are to be executed
