Running shell script through JSP

Hi
I have shell script on my linux server .I want to create a jsp which calls the shell script .Currently i am writing JSP as
string cmd ="sh <path tp shell script>";
Runtime rt =Runtime.getRuntime();
Process p=rt.exec(cmd);
InputStream is = p.getInputStream();
p.waitFor();
I think there is nothing wrong with the concept .The script contains commands which contact the remote server like server on amazon .For running the instance of remote server command is issued and the server will give back the instance id (which takes time of 5 sec ).Based on the instance id given by remote server ,the following commands in script are executed .Now i have a confusion ,is it that commands use remote server connection did not allow the commands to execute properly or there is something wrong in my JSP code ??????
In either cases how do i make my jsp code run???
Plz reply as soon as possible

Hi
Scriptlet will work properly since i have used it in running the script containing local commands like ls , ps, echo and so on...
But for the commands of remote server it did not work.
#2 Understanding of point will be easier if you are familiar of cloud computing .There are some commands like to know the status of our account .They are like normal shell script executed on command prompt .The result is fetch from the cloud (amazon) which generally takes 3 to 5 sec of time .The script containing these commands are working fine but when script is called through jsp page the commands are not executed.
one more thing these command do not required ssh or any other type of login ,only net connection .
Hope it is clear this time
Regards

Running Shell scripts through JAva

Hi,
I tried to execute a Shell script through a Java program.
The code I used is as below:
import java.lang.*;
import java.io.*;
public class sys {
public static void main(String[] args) {
Runtime rt = Runtime.getRuntime();
String[] callAndArgs = { "chgpasswd" };
try {
Process child = rt.exec(callAndArgs);
child.waitFor();
System.out.println("Process exit code is: " + child.exitValue());
catch(IOException e) {
System.err.println( "IOException starting process!");
catch(InterruptedException e) {
System.err.println( "Interrupted waiting for process!");
The "chgpasswd" shell script calls the "passwd" command of Unix.
It threw out an IO exception.
Then I gave the parameter as "./chgpasswd". It now gave an exit value of 255.
The "chgpasswd" script exists in the same directory as the .class file.
I checkd up the exit code reference...it says exit value of 255 could mean as exit code out of range........an exit code > 255....which unfortunately has no documentation, I guess.
Can you help ?

This is on a Unix platform, correct? Assuming so...
If I remember correctly, exit codes can be greater than 255. To get the real exit code equates to something like: exitcode & 512 to obtain the real exit code.
Make sure "chgpasswd" shell script has the execute permissions set. Additionally, make sure that the first line of the script (the magic line) has the appropriate shell/interpreter to execute specified. For example, if "chgpasswd" were a Bourne (sh) script, the first like would be:
#!/bin/shFor perl, it may be something like:
#!/usr/bin/perlIt needs to be the absolute path to the shell/interpreter is the point.

The Runtime.exec methods may not work well for special processes on certain native platforms, such as native windowing processes, daemon processes, Win16/DOS processes on Win32, or shell scripts. The created subprocess does not have its own terminal or console. All its standard io (i.e. stdin, stdout, stderr) operations will be redirected to the parent process through three streams (Process.getOutputStream(), Process.getInputStream(), Process.getErrorStream()). The parent process uses these streams to feed input to and get output from the subprocess. Because some native platforms only provide limited buffer size for standard input and output streams, failure to promptly write the input stream or read the output stream of the subprocess may cause the subprocess to block, and even deadlock.
See JavaApI docs for further info.

Executing shell script through PL/SQL

Hi,
I need some help regarding execution of shell script through Oracle PL/SQL.
I have a shell script present in /abc/xyz folder with name search.sh , Through a PL/SQL procedure I am creating a file to store the report data.
I want to execute /abc/xyz/search.sh from the PL/SQL procedure to delete all files created before 3 mins .
1.     At first I took Java route and got following permissions granted for RECON user.
GRANT USER SYS java.io.FilePermission <<ALL FILES>> execute ENABLED 351
GRANT USER SYS java.lang.RuntimePermission readFileDescriptor * ENABLED 350
GRANT USER SYS java.lang.RuntimePermission writeFileDescriptor * ENABLED 349
2.     Then I created a simple java class for execution of OS command as below
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "OSCommand" AS
import java.io.*;
import java.util.*;
public class OSCommand{
public static String Run(String Command){
try{
Process proc = Runtime.getRuntime().exec(Command);
int ext=proc.waitFor();
return ("0");
catch (Exception e){
System.out.println("Error running command: " + Command +
"\n" + e.getMessage());
return(e.getMessage());
3.     And a wrapper function as below to use this class
create or replace
FUNCTION OSCommand_Run(Command IN STRING)
RETURN VARCHAR2 IS
LANGUAGE JAVA
NAME 'OSCommand.Run(java.lang.String) return int';
4.     In my PL/SQL proceedure I am using following code to execute the command
v_Return := OSCommand_Run('/abc/xyz/search.sh');
to execute the shell script.
Proceedure executes without any error and generates a new csv file with report data , however shell script does not get executed and hence all csv files created earlier remain as it is in the folder.
Please help.

What happens if you remove the catch exception block from your java command?
I asume you still might have a permission issue. But it could be hidden from you, because of the exception is catched and printed into nirvana.Executed the wrapper function OSCOMMAND_RUN as below

v_Return VARCHAR2(2000);
BEGIN
v_Return := OSCOMMAND_RUN('/recon/html/invoice/search.sh' );
DBMS_OUTPUT.PUT_LINE('v_Return = ' || v_Return);

And following is the result
v_Return = 0
Process exited.
In case of exception it would had printed the exception.
One more thing I noticed, even though I have taken following permissions
GRANT     RECON     SYS     java.io.FilePermission     /abc/*     execute     ENABLED     347

GRANT     RECON     SYS     java.lang.RuntimePermission     readFileDescriptor     *     ENABLED     350
GRANT     RECON     SYS     java.lang.RuntimePermission     writeFileDescriptor     *     ENABLED     349
When I create a new search.sh in /abc dir I get following error
v_Return = the Permission (java.io.FilePermission /abc/search.sh execute) has not been granted to RECON. The PL/SQL to grant this is dbms_java.grant_permission( 'RECON', 'SYS:java.io.FilePermission', '/abc/search.sh', 'execute' )

Problems to run shell scripts in terminal

Hey mates,
I'm not very experienced in writing shell scripts. However, I received a few shell scripts I wanted to execute. I used following command:
chmod u+x model.sh
I did not received any error message so that I think that this command works. Afterwards, I wanted to run these file with:
./model.sh
However, it doesn't work, I receive an error message:
-bash: ./model.sh: /bin/sh^M: bad interpreter: No such file or directory
If I choose another shell script of my colleague I can run it and it works properly. What's the problem?
I use in all shell scripts the same syntax starting with
"! /bin/sh
Thus, I don't see the reason why the first script isn't running while the second one is fine.
Help appreciated!
cheers,
Thomas

Unix and Terminal questions are best asked in the Mac OS X Technologies > Unix Forum
<http://discussions.apple.com/forum.jspa?forumID=735>
As jsd2 has pointed out, you CANNOT have Windows <CR><LF> line terminators in your file (aka ^M^J). Just about every Unix shell will choke on the <CR>
We run into this problem all the time with users moving Unix shell scripts through a Windows system and having Windows convert the <LF> terminated Unix files into Windows <CR><LF> files, and then either use them in a Windows Cygwin environment (where they "Barf"), or move them back to a Unix system with the <CR><LF> line terminations still in the scripts, and they "Barf".
You can look at the contents of your scripts using the following command
cat -v script.name
Any ^M characters found at the end of lines will be part of <CR><LF> Windows line terminators.
You can use the following command to remove the <CR> from those files
tr -d '
' <script.name >new.name
chmod +x new.name
If you wish to pursue this further, I would suggest using the Mac OS X Technologies > Unix Forum

Apple Automator - Run Shell Script Application

Morning, hope somebody can point of my error please.
I'm attempting to create an Application wrapper for a minecraft server.
I've done the following
Automator > Application
I've dragged in 'Run Shell Script'
The Shell dropdown is '/bin/bash'
The Pass input is 'as arguments'
In the script I have '
cd /Volumes/3Tb/Bukkit_live
/usr/bin/java -Xmx2G -jar /Volumes/3Tb/Bukkit_live/minecraft_server.jar nogui
Now when I run it through the automator app, it works fine, the server starts, however when I try and run it as a standalone application it does nothing ?
Please help.
Thanks in advance.
Darren

Best guess is that there is an environment variable in your Terminal session that does not exist when you are running an Automator workflow.
You could try running an Automator workflow that does Run Shell Script with something like
( pwd
id -a
echo $#
echo "$@"
printenv
) >/tmp/automator.environment.txt
Then do 2 things. Run it within Automator and copy the /tmp/automator.environment.txt file someplace safe. Next save it as an Automator app and run it that way. Compare the 2 automator.environment.txt files and see if anything significant is different between the 2.
This is just a guess (an educated guess, as this sort of thing has happened to others in the past when they see a difference between running a script interactively and running it as an embedded app).

Running shell scripts from within oracle. A big task is forgotten

Dear List,
I have some shell shell scripts which do some tasks on the linux OS level.
I am calling the Korn scripts using a java class, which in turn is being called from a PLSQL function.
All but one of the 10 script works fine. This is the script which does the most work, and takes on average 40 minutes usually.
Why does Oracle forget the running of the shell script? I wait in my PLSQL function for the return code, but it never comes. The scripts I have not written myself !
I look forward to your reply on this matter.
regards
Ben

Hi
If you are using the Oracle database 10g, the new dbms_scheduler package allows you to run shell scripts. The dbms_scheduler.create_job procedure have one parameter called the job_action in which you specify the full path of the shell script.
I hope this will help

After completion of this process, I am running another script which takes that file name and trying to create a external table. The both scripts are runnning successfully. But while I am trying to run using process flow, its not coming.
And I am not getting the way to catch the output of external process and pass it as parameter as another external process.
Any suggestions are welcome.
Thanks and regards

Trouble using Run Shell Script with python in Automator

Hi. I have a python script I want to run in Automator (update_puzzles.py). All it does is check, rearrange and update files and there is not supposed to be any input. I can get the script to run outside of Automator, in Terminal, by navigating to the right directory and typing "python update_puzzles.py"
I must not be setting up Run Shell Script correctly. I have it set to /bin/bash and Pass Input to stdin. The command line simply reads python /pathname/update_puzzles.py (where pathname is the path to the .py file, which I got by dragging the file onto the Run Shell Script command window). There are no actions before this in my workflow and the action after is View Results.
The log says Run Shell Script failed, and the error is "Traceback (most recent call last):"
Any suggestions?
Thanks so much.

If the script is expecting to do stuff with files in the same directory as the executable, you will probably need to add a statement to change to the appropriate working directory. The shell used in the Automator *Run Shell Script* action is a generic one that does not share any of the environment variables that the Terminal uses.

How to pass video file name to run shell script

Trying to make an automator script that will 1. Start a video capture, 2. Stop video capture, 3. Rename video, 4. Run Shell Script. Here is the shell script:
for f in "$@"
do
echo "$f"
/usr/bin/podcast --server my.podcast.server --user myself --pass mypass --submit --file $f --workflow "my workflow" --metadata /path/to/file
done
Question:
Do I need to create a variable in the automator script to pass it to the script? If I need the variable do I also need to use both Set Value of Variable and Get Value of Variable? If I don't need a variable does $f need quotes around them?

I'm not familiar with the terminal command /usr/bin/podcast so I don't know what it does but what i said is correct. to pass a file to this action you don't need any variables. the previous action in the workflow should output the video file you want to process, that's all. how you arrange that is up to you. it's clear that you have to fill in appropriate things in that shell script like " my workflow" and path to metadata. But if you have questions about how this shell action works you should ask people who made it.

Pass multiple Automator variables to Run Shell Script?

I have two Automator variables I'd like to pass to Run Shell Script. I'm missing something obvious, but how is this done?
Thanks in advance

i don't know a nice way to do it but in general any input passed to a shell script will be stored in $@ if input is passed as arguments.
in particular, if you stack two "get value of variable actions" one after another and follow it by "run shell script" both variables will be stored in $@ as a list. just try it out with the default
for f in "$@"
do
echo "$f"
done
You'll see that both variables will be echoed.

Running Shell Script

Hi all,
I need to run shell script on one of linux servers while executing some IdM workflow.
There is no need to manage that server/ provision accounts / reset passwords etc but just to run the script and to process the result.
I have IdM 8.04 installed on Windows Machine.
What are my options to achieve that mission?
Thank You,
Alex.

I was considering a situation similar to AD after actions where sometimes we execute a dos batch file for any specific purpose like creating home folder using mkdir. I was thinking on similar lines if your shell script is also for a specifc function similar to the one I mentioned above and if it is applicable in windows environment, you might covert that into a dos batch and do similar to an after action.
Since you need your shell script to be run in UNIX / LINUX machine, I do not see any other way other than writing a java class and invoke within a wf as it was mentioned by etech or if you are planning on using any of the out of the box resource adapters, the AIX resource adapter reference might help, but I have not worked with that

Automator and "Run Shell Script" error

First, if I'm in the wrong place with this- sorry. Figured this was an OS kind-of thing.
I recently migrated to a new iMac ... I brought along an Automator script; I've been using it for years to perform a little rsync backup to an USB HDD. It's 'never' given me any problems ... until now!
"*Run Shell Script*" encountered an error .. but alas, the system log is devoid of messages ... and the verbose log I have running indicates that all the files are copied/backed-up ... I would love any input on this that might help me get back on the feet. .....
*Here's what my Shell Script Looks like:*
Shell Option: /bin/bash
Pass Input: to stdin
rm -dfr '/Volumes/Backup HD/*********'
rm -dfr '/Users/***********/Library/Logs/Profile_Backup.log'
rsync -rltv /Users/******** '/Volumes/Backup HD/' > /Users/*******/Library/Logs/Profile_Backup.log
(I'm sure there's way to only sync the changed stuff between backups ... but I've simply preferred the fresh copy approach).
*I do however note this in my logs when I open Automator:*
12/14/10 3:15:46 PM [0x0-0x42042].com.apple.automator.Backup[464] Application Stub: OpenScripting.framework - scripting addition "/Library/ScriptingAdditions/Adobe Unit Types.osax" declares no loadable handlers.

@Tony T1
Thanks, I'll certainly adjust the log file as suggested
In troubleshooting the problem I went the terminal route - and issued each command ... during the rsync process I was getting an error ... turns out when it was syncing the SyncServices folder it was encountering a copy of the keychain ... which had root permissions - naturally rsync was not able to copy the file (personally I have no idea why the keychain would be being sync'd with anything)!
I removed the file from the sync ... I'm still doing some "debugging" to correct the problem-
Again, thanks for the assist!
