Run java shell script on Linux

Hi I am just trying to convert a Windows batch file to a unix shell script to run a java application, but it so long since Ive used UNIX I cant really remember how to do it.
My script contains
#!/bin/sh
java -jar lib/testapp.jarThese are my failed attempts to run it, not too sure what the differences are but I think the 3rd one is the only one to actually find my shell script.
[root@]# testapp.sh
-bash: testapp.sh: command not found
[root@]# ./ testapp.sh
: bad interpreter: No such file or directory
[root@]# . testapp.sh
Unable to access jarfile lib/testapp.jarif I just do this at the command line it works fine
[root@]#java -jar lib/testapp.jar

#1
[root@]# testapp.sh
-bash: testapp.sh: command not found
#2
[root@]# ./ testapp.sh
: bad interpreter: No such file or directory
#3
[root@]# . testapp.sh
Unable to access jarfile lib/testapp.jar#1 is because the command (testapp.sh) is not found on the PATH. Under Unix the current directory . is not included automatically in the PATH: it has to be excplicitly specified, and this is a good thing. Also make sure it has the x (executable) switch on: chmod +x testapp.sh
#2 is because you had an extra space in what should have been
./testapp.sh #3 there you could "inline" the script but the file lib/testapp.jar was appearently not found. Is lib really under the working directory or in other some place?

How to run unix shell script from java web applet

hi all
i have created one java applet. my apache web server is on unix server.
i have created one shell script in same directory where my .class and .htm files reside...
how to run this shell script from applet? it should search this .sh file on server and not on the client browser machine...
thanks in advance

I suppose you could make the shell script into a CGI, configure the server to execute CGIs, and then make the applet open the URL of that CGI.

I'd be very grateful if you could show me sample code...
Have a great day,

Runtime.exec()
There are plenty of examples. Read the following before continuing, however, as it will save alot of headaches:

Do I run a shell script (bsh) via PL/SQL stored procedure?

Hello guys,
Do I run a shell script (bsh) via PL/SQL stored procedure?
For example:
procedure X is
(variables)
begin
-- Read file data
vFileHandle := utl_file.fopen('/mnt/novell/', 'file.txt','r');
exception
when 'INVALID READ FILE' then
(I've to try running script to mount a Novell partition.);
end;
I've to installed Oracle 9.0.1 on Suse Linux.
Please, any ideas or hints ...
Thx and regards.

You might be able to us the HOST command, I think you'd have to run it via dbms_sql, check this page for more details, not sure if it'll be of help but its worth a try..

How to run a shell script from the GUI?

This is probably a dumb question...
How do I run a shell script from the GUI? I've been told to double click it but when I do, it opens as a text file.

The behavior you describe is that used by the KDE and GNOME desktops of Linux.
Under OS X, if you make a script then mark it as executable, double-clicking on it in the Finder will not execute it. Actually, it uses a rather complex algorithm ([summarized here|http://arstechnica.com/reviews/2q00/macos-qna/macos-x-qa-2.html]) to determine what to do with it. This is implemented in Mac OS X' LaunchServices framework (incidentally, the associations are cached in /Library/Caches/com.apple.LaunchServices*.csstore and ~/Library/Caches/com.apple/LaunchServices*.csstore). You can read the details in the developer docs about LaunchServices.
Anyway, in short, the suffix '.command' is a built-in type in the LaunchServices network that identifies a shell script. If you run
/System/Library/Frameworks/ApplicationServices.framework/Frameworks/LaunchServic es.framework/Support/lsregister -dump
... it will tell you as much.

Secure login to remote UNIX host and run a shell script

Hi I am new to JAVA. I want to login to remote UNIX host from my application secure login (SSH) and run a shell script reside that remote host. Can any one let me know the way how to do it. If possible provide the code example.

Runtime.exec with an ssh command (not really recommended).
Much better, an SSH API (JSch, which needs JZlib, from http://www.jcraft.com/ is a good one).

How I run a shell script from the scheduler on 10.2.0.2.0 ?

Hello Oracle People,
I'd like to run a shell script from the Scheduler in my 10g database.
Right now it is a simple shell script.
Eventually it will wrap RMAN commands to back up my DB.
I wrote a simple pl/sql script to create a job:
-- cr_job10.sql
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
job_name => 'my_backup_job',
job_type => 'EXECUTABLE',
job_action => '/h/oracle/scripts/tst.sh',
start_date => '06-SEP-07 5.33.00PM US/Pacific',
repeat_interval => 'FREQ=DAILY',
end_date => '08-SEP-07 4.00.00PM US/Pacific',
enabled => TRUE,
comments => 'My Backup Job');
END;
I see no errors when I run the above procedure.
I checked DBA_SCHEDULER_JOBS and the job is in there.
The scheduler, though, errors out with an error which I see in a trace file:

There, I see some evidence that I need to configure something inside

for machines running windows. I'm running Solaris.
Do any of you know what I need to configure inside of Oracle to
run shell scripts from the scheduler?

Hello people,
I should have added this bit of information:
"The script runs fine from oracle's crontab."
"The script runs fine from a shell owned by oracle."
I'm getting responses telling me to check my env variables and permissions
which would be helpful to a UNIX novice.
I have a feeling that no one is using the scheduler to run RMAN scripts.
Tim Hall suggested I take a close look at these files:
$ORACLE_HOME/rdbms/admin/externaljob.ora

I am focused on this error:
ORA-27369: job of type EXECUTABLE failed with exit code: 274662
And I am focused on this exit code: 274662
What does 274662 mean?
If the Scheduler gives me an error like "274662" rather than some English,
it's obvious to me the Scheduler is a POS and I should not use it.
And of course,
If I cannot run RMAN from Oracle Scheduler, I'll use cron.

How do I run a shell script via AppleScript?

Seems obvious, "do shell script" but that doesn't work for me.
I have an Automator app which runs a shell script, I'd like to take that into an AppleScript. My AS doesn't run the shell script. Perhaps "do shell script' is expecting the script to be located elsewhere? The rest of my AS runs fine, but the shell script doesn't.
repeat with i from 1 to count of items in exportFolder
do shell script
          "exiftool -overwrite_original -Photoshop:CopyrightFlag='True'"
done
end repeat
As I say this works within an Automator app, what changes do I need to make it work in AppleScript?
Thanks!

Camelot wrote:
repeat with i from 1 to count of items in exportFolder
What is 'exportFolder'? Where is it defined?
Thanks, 'exportFolder' is defined earlier in the script. The purpose of the script - which is run from within Aperture - is to rename the selected images, export them (to the 'exportFolder'), reset the version name and, using ExifTool, add metadata which Aperture does not write to exported JPEGs.
I have a version of this which works in Automator but I couldn't see any clues there on setting the path to ExifTool.
Here's the full (modified) script. Currently it returns an error
Result:
error "No file specified" number 1
so I now need to understand if I can use 'exportFolder' (defined at the start) to tell Finder which folder to use.

Run a shell script from FORM

Hi,
Is there a way that we can run a shell script on UNIX box from ORACLE FORMS 4.5 running on client PC (OS=windows on client,
DB on unix).
Thanks in advance for help

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Anton Weindl ([email protected]):
You can either use rsh or rexec (both available on windows). You will have to edit the .rhosts in the home directory of the unix user the script will be run under:
<Client-Hostname> <USER>
<USER> must match the Windows-User exactly.
You can then execute the Shell-Script with
host('rsh <HOST> -l <USER> sh <SCRIPT>',NO_SCREEN)
Hope that helps

<HR></BLOCKQUOTE>
Thank You Anton Weindl,
It seems like the thing I want to use instead of the dbms_pipe.
I tried to use rsh and gives me the following message
command: "rsh taurus -l nileshs test.sh"
where taurus is hostname and
guest is unix username
I am logged on windows 2000 with this name.
"taurus permission denied:"
"rsh can't establish connection"
Let me know if I am missing anything.

Problem with running Bash shell scripts

I am unable to run Bash shell scripts on the UNIX Terminal application.
This is the transcript from the Terminal application.
Zhi-Yang-Ongs-Computer:/Applications/MetaPost/metapost-1.102 zhiyangong$ ./test1.sh
dyld: Symbol not found: _BC
Referenced from: /usr/local/bin/bash
Expected in: /usr/lib/libSystem.B.dylib
Trace/BPT trap
Zhi-Yang-Ongs-Computer:/Applications/MetaPost/metapost-1.102 zhiyangong$
Is this a problem with the the default installation of the Bash shell? Can I install the Bash shell on my own? If so, how can I do that?
Also, how can I get the dynamic linker, dyld, to refer to the symbol "_BC"? What does this symbol "_BC" refer to?

This was in your posted output:
/usr/local/bin/bash
You are NOT running the default bash, you are trying to run a private copy.
The default Mac OS X bash is located at
/bin/bash
Try the following:
/bin/bash ./test1.sh
Does that work?
What is the first line of your script? Is it:
#!/bin/bash
Or maybe
#!/usr/bin/env bash
/usr/bin/env would find the first bash in PATH . I find this most useful for finding perl on different systems, but sh, ksh, bash, zsh, csh, tcsh are all generally found in /bin so I do not bother using /usr/bin/env
And if you have
#!/usr/local/bin/bash
Then the person that wrote test1.sh choose to use something besides the default bash
Or maybe this script was transferred from some system where you needed to put your own copy of bash in /usr/local/bin because the vendor does not distribute bash
Then again, you have not showed us what is inside your script, so it is possible something in the script called something else which invoked the /usr/local/bin/bash
If that is the case, then you might try:
/bin/bash -x ./test1.sh
which should show you the commands executed before it died.

Problem with executing shell script on linux through java code.

but when i am running through java code its not working.
the java code i am using is:-

Running UNIX shell scripts from a Java app

I want to build a GUI in Java as a front-end to a collection of UNIX shell scripts I have written. Is this possible?

It is possible, but it kinda defeats the purpose of shell scripts no?

Use java to run a shell script which called a crontab command at Unix

I was trying to write an automate function using Java, which needs to call a shell script containing a crontab commend. The shell works fine without that crontab commend, but once I add it, the program won't execute that crontab commend.
public void cron(){
try
Process proc = Runtime.getRuntime().exec("script1");
BufferedReader br = new BufferedReader(new InputStreamReader(proc.getInputStream()));
String line;
while ((line = br.readLine()) != null)
System.out.println(line);
int returnValue = proc.waitFor();
br.close();
} catch (Exception e){} //
script1:
#!/bin/sh
crontab cronfile
Can someone help me out for this? Thank you.

Try this....
Process p = Runtime.getRuntime().exec("sh");
java.io.BufferedWriter bw = new java.io.BufferedWriter(new java.io.OutputStreamWriter(p.getOutputStream()));
bw.write("script1");
bw.flush();
bw.close();
