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).

Can you write simple Java code in a UNIX function and run it? See example....

Hi,
I'm new to Java and I have a question.
Is there any possible way a simple script like the below would work in a UNIX function called from a shell script. I know you're not supposed to do this but can you?
Thanks in advance,

No!
This is neither a valid answer to the OPs question (since your script does not create the content of Test.java) nor working.
The java executable can only run *.class files which contain byte code of the intermediate language generated by the javac executable.
Your suggestion leads to a ClassNotFound exception.

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

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.

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
of Oracle to run shell scripts from the scheduler, but possibly just
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:

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.

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..

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.

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:

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

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.

Run a shell script at login?

I would like to run a simple shell script each time a user logs in. Currently, I have it wrapped in an Automator executable that is included in "Login Items", but figured there must be a more elegant way? Thanks.
More info:
The problem I'm trying to solve is that of file permissions when sharing one iTunes and one iPhoto library between multiple users on one computer. The libraries are located in /Users/Shared and the apps were pointed to the relocated libraries by holding down 'Option' on startup. The problem is that work done by each user in the iTunes or iPhoto library inherits the default permission settings of that user, making any new additions to the libraries, read-only to the other users. I'm using `chmod` on login to fix it. Let me know if you know of a better way to address this. Thanks again.

I wrote a simple shell script that executes each time a user logs in (well, actually, each time I log in, coz' it's not really applicable to other users). It syncs my work and home addressbooks and iCal calendars to one another.
I named it "sync". Then I read somewhere that if you wanted to make it double-clickable (to launch it from the Finder), I appended a ".command" filename extension (so it's now named "sync.command"). I also did a chmod 755 to that file so that it had execute privileges. Depending on whether you give each user their own copy of this thing, or keep a single copy in, say, the /Users/Shared directory, you may have to play around with chmod. Whatever, just so long as the user that has just logged in has execute permissions to the file, and to the entire path to the file, you should be good.
Then, in SysPrefs > Accounts > Login Items, I added that "sync.command" file to the list. So, really the only difference is I'm not wrapping mine inside an Automator script like you are.
I had tried adding it to ~/Library/LaunchAgents and make a launchd plist for it, that would kick it off at login. But I didn't get that to work. Don't know why. But just adding the double-clickable executable unix script to the Login Items list did the trick. Whether the plist has to hang out there with it, I don't know. I still have it there, though, in case I ever get motivated to figure out what's wrong with my launchd plist file. So, if just adding it to the Login Items list doesn't do it for you, you could try making a (functional?) launchd plist for it and plopping them both in ~/Library/LaunchAgents, too. That's how I am now, and, like I said, it launches at user login as that user's process (not as a root process like the above referenced article said how login hooks worked -- although, you may want it to run as root since you want this to work with multiple users...in which case, you might want to listen to Cole and not me...).

Opening a document in photoshop and running a ps script

I'm trying to write a script which will open a link in photoshop (which I have managed to do with Link.editOriginal) and also run a photoshop script after the file is opened. I have looked in online references and the PDF's found on this site, but I can't seem to find a function which will let me run a ps script from inside Indesign. Is there any method of doing this, or am I out of luck?
Thanks for your time.

Gerald Singelman told me to check the status of a link in a loop before executing the update()-command.
This is the updated version:
// resizeInPS04.jsx
//DESCRIPTION: Resizes every link in PhotoShop
var theScale = 150; // scaling factor in %
var theResolution = 72;
var theResampleMethod = 'ResampleMethod.BICUBIC';
var myChoice = confirm ('Warnung! \rBei Ausfühurng dieses Skriptes werden unwiderruflich alle verknüpften Bild-Dateien verändert. Machen Sie vorher Backups der Dateien.' );
if (myChoice == false)
exit();
var myLinks = app.activeDocument.links;
for ( var i = myLinks.length-1; i >= 0; i-- )
ResizeInPS( myLinks[i].filePath, theScale, theScale, theResolution, theResampleMethod );
while (myLinks[0].status == LinkStatus.NORMAL )
// think about the weather
myLinks.everyItem().update();
for ( var x = myLinks.length-1; x >= 0; x-- )
myLinks[x].parent.fit( FitOptions.FRAME_TO_CONTENT );
function ResizeInPS(myPath, myHorScale, myVerScale, myResolution, myResampleMethod) {
   var bt = new BridgeTalk;
   bt.target = "photoshop";
   var myScript = 'try {\n';
   myScript += 'var myPsDoc = app.open(File(\"' + myPath + '\"));\n';
   myScript += 'app.preferences.rulerUnits = Units.PERCENT; \n' ;
   myScript += 'myPsDoc.resizeImage(' + myHorScale +', ' + myVerScale + ', ' + myResolution + ', ' + myResampleMethod + '); \n' ;
   myScript += 'myPsDoc.close(SaveOptions.SAVECHANGES);\n';
   myScript += '}\n';
   myScript += 'catch (myError) {\n';
   myScript += 'myPsError += \"myError' + myPath + '\";\n';
   myScript += '}';
   bt.body = myScript;
   bt.send();

How does one run a shell script at system startup?

Hi,
I am trying to unmount my Boot Camp hard drive on my MacBook Pro. Now what I could do is create an automator action, save it as an application and then put it into my user´s login items. I am wondering though - shouldnt it be possible to run a simple shell script command like +diskutil unmount /Volumes/"Boot Camp"+ sometime during the startup process?
Or to put it another way - is there an easy way to do this or do i have to create an manage a daemon through launchd ?
Your help is very much appreciated.

sorry I forgot to mention that there is a bug in Lingon which creates a plist incorrectly if you enter your script explicitly on line 2. At least I haven't been able to make it work. A workaround I always use it the following.
Save your script as a *plain text* file from your favorite text editor. change the extension to .sh and make the file unix executable. Now, when you ccreate a launch daemon using Lingon, enter the path to that file instead of the script itself.
This always works for me.
Good luck!

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?
