Running a Perl script

I have two things I need to do. First is, figure out how to run a perl script. Second, I need to use the cron to run it every 2 hours.
How would I do both of these?

crontab -e
0 0-23/2 * * * curl "http://... "
Will run the command every 2 hours on the hour. If you want to run a quarter after the hour then
15 0-23/2 * * * curl "http://... "
Change the first number to whatever minute after the hour you want the cron job to run.
See the man page
man 5 crontab

Under a GUI, I need to run a perl script, how to do this?

Hi - I am writing a GUI for my clients and one of the things my program must do is run a perl script. I am able to run perl.exe but it seems like perl.exe is not running the script. I also tried to put the perl script in a batch file and then call the batch file from my java GUI program. I still get the same issue of just perl.exe running but thats not running the script. My last attempt was to write a small class to test if perl.exe can run the script under a command line. I got the perl.exe to run the perl script but how do I but implement that class in my GUI if my test class needs a command line? How can I run a command line in my GUI so the perl script can be run.
The Runtime.getRuntime.exec(RunPerlScript) is not working like I want it.
I also tried Runtime r = Runtime.getRuntime();
Process p = r.exec(RunPerlScript);
How can I run the MS-DOS prompt from my program if the Runtime Environment is running already. The Runtime Environment seems to not allow another prompt to be opened and from there I can run the perl script manually or automatically from my program.
What does the "cmd /c start..." or "c:\\windows\\command.com..." do? I have seen that in the forum but it doesn't seem to be running the perl script. The perl.exe runs, but not the perl script. I need anyones help desperately. Damn microsoft, why did they remove completely the functionality of DOS. I have a feeling my program will run perfectly under a UNIX environment, because I needed to do was open another shell. Thats what I need in windows!
Thank you for your help.

Is there any possibility running a Perl Script in JSP?

Is there any possibility running a Perl script in JSP and get the value of the JSP variable? The JSP page is running in TOMCAT 5.0 server.

i am created one script .... i want to replace it the older one ... it is possible in development server ..... is there any possibility to assingn the form in quality server ?????
is there any other way to assign the form to transaction with out using NACE?.
Well regarding you question about the system to have it assigned, ideally you need to assign it in development and mopve it up stacks. However, i aint sure of the roles you are assigned with for doing any config changes in QS. and the config needs to be done through NACE. Following is the process.
You need to first find the Output type and the standard form attached to the existing program/ tcode. This info can be fetcehd from TNAPR table. Once you have got the details, you can then get into NACE tcode to configure your new custom form instaed of the existing Standard one. Get the application type, output type from TNAPR table. Then select the particular outpput type in NACE nad click on processing routine. This is the place where the new form name needs to be updated.
Hope this helps!
Cheers!

How to run the perl script from java ?

Hi , I need to run the pearl script from the server and to get the result of the script thro' java using SSH
Is there any 3rd party SSH API in java ?
Please help me out
thanks in advance
karthik

This seems like a very strange thing to want to do.
What is the perl script doing?
Do other programs (not some shell script) access this server-side perl script from a different machine?
If so how do they do it?
What currently triggers the perl script to execute?
What currently handles the output from the perl script?
If you can answer these questions (and understand the answers) you should be able to come up with a different approach to this.
You do not really want to call a remote perl script from a Java program, you want to achieve the effect you think that would have if you could do it.
So find the answers to the above questions, write them on 3" x 5" cards and lay them out on your desk.
What flow of control needs to happen? Which piece of code needs to produce or consume which piece of data?
If that fails, ask you self or who ever is making you do this what are the use-cases?
If you do not know what use-cases are or do not understand them well enough try reading
Use Case Modeling (The Addison-Wesley Object Technology Series) by Kurt Bittner and Ian Spence (Paperback - Aug 30, 2002)
http://www.amazon.com/s/ref=nb_ss_gw/002-7908514-4043267?url=search-alias%3Dstripbooks&field-keywords=use+cases&x=0&y=0
It is a short and easy to read book on the subject and also one of the best.
You MUST understand WHAT you are trying to achieve before you can decide HOW you are going to achieve it.

How to run NMS perl scripts in SunONE 6.1

Any one have info on running the NMS perl scripts with the perl compiler shipped with 6.1? Particularly interested in nms FormMail. I need to get it running in on windows xp and Sun Solaris.

The Perl you found in the bin/https/perl directory is a private copy of Perl used to implement parts of the Web Server Administration Server. You shouldn't try to use it to run CGI scripts.
Instead, you can download your own Perl distribution. ActiveState has a Perl distribution called ActivePerl. You can get it for free from http://www.activestate.com/Products/activeperl/. Other options are listed at http://win32.perl.org/.

Running a perl script outside local directory

so i have been trying to write a java program that calls a certain perl script "helloworld.pl" using the runtime.exec method.
Runtime.getRuntime().exec("perl helloworld.pl");the problem comes in when i attempt to run a helloworld.pl that is not in the local directory.
Runtime.getRuntime().exec("perl C:/helloworld.pl");how would i properly execute the line of code above?

and since 'perl' will pick up files from the current working directory you can also use
Process process = Runtime.getRuntime().exec("perl helloworld.pl", null, new File("C:\\")); // or whatever directory is your perl program is in.P.S. You should read thoroughly the 4 sections of [http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html|http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html] and implement ALL the recommendations.

Perl script run

I have a perl script that has to be run by a servlet ....
Can anybody tell me how to do that or where to look for some tutorial or
code to learn the process.
Thanks in advance.

Run the perl script as a cgi script. Have the servlet call the cgi script using HttpURLConnection.

I have perl scripts that I want to be able to run with my iplanet web server 6.0. How can I make it work in Windows NT? (Because I have no problem when I use it with Linux).

Hi Melanie,
In order to run a PERL script under Windows NT the iPlanet Web Server needs to know where to find the PERL interpreter.
follow these steps :
1) Make sure Windows NT knows what a .pl file is. In file Manager click on file and choose associate from the menu. Check the "files with extension" drop-down list for pl - if it exists verify that it is pathed to your perl.exe. If it is not already on the list click the "New Type" button. In the Filetype box put pl. Choose open from the Action drop-down list. In the Command box specify the full path to your perl.exe interpreter (Make sure to use short filenames, rather than long filenames.) Click the OK button. Then click the Close button in the main Associate dialog box. Double click a .pl file to test - it should automatically launch the PERL interpreter and feed it your .pl file.
2) Create a directory to contain your .pl scripts.
~server_root\shell-cgi is a good choice.
or \cgi-bin\
NOTE: Make very sure that this directory is NOT part of the document root, it should have it's own directory (preferably at the same level of the docroot).
3) In the Admin Server select Programs.
4) Choose CGI directory (normally) or WinCGI directory or ShellCGI Directory depending on ur choice from the Programs menu.
5) Put the URL Prefix you would like to map to your Shell-CGI directory into the URL Prefix field.
6) Put the full path to your Shell-CGI directory in the Shell CGI directory field.
7) Click OK.
8) The save and apply changes page will display your changes and give you the opportunity to verify them. If they are correct click the Save and Apply button. If not Click the Undo button and go back to step 4.
(9)You can then call your .pl scripts directly by referencing the directory mapping that you have just created. For example:
http://my.server.whatever/shell-cgi/ myscript.pl
this should work now.
If not Pls Mail me.
regards

Problem in running Perl script through oracle

Hi,
I am facing one problem in perl script.
" I have one perl script which is interact with sybase database.We have migrated the sybase database to oracle successfully.Now i wanna to change the perl script to interact with oracle database.
I am using the code like that for interacting the oracle database
Old Code with sybase database : use DBI::Sybase::GFAS;
New code with oracle database : Use DBI::oracle::GFAS;
When i am running the perl script,Its showing the below mentioned error:
Can't locate DBI/oracle.pm in @INC (@INC contains: C:\oracle\product\10.2.0\db_1

\sysman\admin\scripts C:/Perl/lib C:/Perl/site/lib .) at hello.pl line 4.
BEGIN failed--compilation aborted at hello.pl line 4.
Anyone have any idea about this error.
Thx in advance.

If you look in the oracle home in the perl\site\5.8.3\lib\MSWin32-x86-multi-thread directory you will see two directories. Once is DBI and one is DBD.
All you need in your perl program is a line 'use DBI'. It will use DBD automatically as and when required. You can specify the necessary connection information when you issue the DBI->connect statement.
I have successfully managed to connect to Oracle databases and perform DML using the software installed by default. You don't need to download and install anything else.
I'm no perl expert so maybe some functionality is missing using the interfaces provided by Oracle but for my needs it has sufficed.
Hope this helps.

Perl script running - "text file busy" error?

Hiya--
Recently, whenever I try to run a perl script, I get the following error:
tcsh: nameofscript.pl: Text file busy.
The permissions on the perl script are set to 755, and this error message occurs whether I type "nameofscript.pl" or "./nameofscript.pl" at the prompt. The initial line is of the script is
#!/usr/bin/perl
Has anyone else encountered this problem? I can't for the life of me figure out why it's occurring now. (I've run this script before without any problems. It's only within the last 2-3 weeks that this error pops up and won't go away, and only for .pl scripts.)
Advice much appreciated.

Hi Mahesh,
I could suggest you some services that you may stop in Windows platform.. If not You may look into some services
with analogous names and stop them. But you may go about stopping all database and SAP J2E services.
The services are

Can I run perl scripts on a iplanet App Server instead of web server

Hello,
We have some perl scripts running on a iWS 6.0 in DMZ (Tier1) which acess Oracle Server(Tier 3). I want to restrict machines on DMZ access Oracle server directly. Instead I want all the database calls to orignate from iPlanet App server on Tier 2. To make this happen I have to run Perl scripts on App server. Is this feasible as the J2EE iPlanet App can run only C++ or Java.. Any leads helps me lot..
Thanks
Sudhir Nallagangu

According to the J2EE specs you should use EJBs and Servlets in the iAS! Running a perl script for db access sounds like good old cgi times.
But generally it is possible to call a perl script from within iAS. But don't do it!

Runtime.exec("Perl Script writing and reading on I/O"), handling Streams

Hi all !!
In a first place : sorry for my english if it's not really understandable but I try to do as good as possible !
I'm writing a GUI with Swing that will allow (in one of my multiple tables) the user to run a Perl Script.
This Perl Script ask the user to choose a Folder ... then read all the files in this folder and for each file (xml File), extract the datas and put them in a database. But when a file that has to be inserted in the database contains this line : <Template_Used name="ST1.mtt"> and if the Template table in my database doesn't have the "ST1.mtt" stored ... the Perl Script ask to the user to give him the path of the file "ST1.mtt" so that the script can put the "ST1.mtt template" datas in the database.
This script runs well when it is from a windows console.
But I need a graphic interface !!!
So I created a JButton "Process a folder".
When the button is pressed, a JFileChooser appears and ask the user which Folder has to be processed.
Then a Process is created with the command : ("cmd.exe /C \"C:\\Program Files\\Fluke\\Ansur\\ProcessFolder.bat\").
The BatFile :
{code}cd C:\Documents and Settings\tsd\Desktop\Gael-Project\Project_Files
perl Process.pl
exit{code}
At this moment everything is working well.
But my Process.pl (which is 300 lines long ... and that you don't even want to hear about), ask in a first time the Path of the folder to process and sometimes ask the path to a file (a template file).
So I need to read and wirte on the STDIN/STDOUT during the exec of the Process.
In order to handle this I created two different threads : one reading the Process.getInputStream with a BufferedReader and one other writing on the Process.getOutputStream with a PrintWrinter.
What I need to do is :
When I read a line from the InputStream saying "I need the path of the ST1.mtt file", I should run a JFileChooser ... the user find the file in the computer ... and I write in the OutputStream the path of the file, so that my Perl Script doesn't have un Unitialised value on <STDIN> and can continue to process !!
I'm pretty sure it's possible ... because at the moment I just used a trick :
When the user push the "process a folder" button, I write the paths in the OutputStream before than the script needs it and it works !
But I need to write in the OutputStream only when it is time !!!
Any idea ??
Here are some parts of my code :
{code}
String filename = File.separator+"tmp";
          JFileChooser fc = new JFileChooser(new File(filename));
          fc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY );
          // Show open dialog; this method does not return until the dialog is closed
     fc.showOpenDialog(null);
     Folder = fc.getSelectedFile();
          new GoodExec(cmd);
{code}
{code}
public class GoodExec {
     public static Process proc;
     public static StreamGobbler errorGobbler;
     public static StreamGobbler inputGobbler;
     public static StreamGobbler outputGobbler;
     public GoodExec(String cmd)
     try
               Runtime rt = Runtime.getRuntime();
          proc = rt.exec(cmd);
     // any error message?
     errorGobbler = new
     StreamGobbler(proc.getErrorStream(), "ERROR");
     // any input?
     inputGobbler = new
     StreamGobbler(proc.getInputStream(), "INPUT");
     // any output?
          outputGobbler = new
          StreamGobbler(proc.getOutputStream(), "OUTPUT");
     // kick them off
     errorGobbler.start();
     inputGobbler.start();
     outputGobbler.start();
     // any error???
     int exitVal = proc.waitFor();
     System.out.println("ExitValue: " + exitVal);
     } catch (Throwable t)
     t.printStackTrace();
{code}

     if (os == null){
     InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line=null;
String comp = "Please enter the exact path of the directory that contains the files you want to process.";
while ( (line = br.readLine()) != null){
     if (type.equals("INPUT")){
          chaine+=line+"\n";
     if (line.equals(comp)) {
          System.out.println("give directory");RUN A JFILECHOOSER AND GIVE THE DIRECTORY TO THE OUTPUTSTREAM
System.out.println(type + ">" + line);
is.close ();
catch (IOException ioe){
     ioe.printStackTrace();
{code}
And here is an example of a simple perl script that could be used (it s a simple one !!) :
{code}
#!/usr/bin/perl -w
use strict;
print "Please enter the exact path of the directory that contains the files you want to process.\n";
my $dir= <STDIN>;
chomp ($dir);
print "titallala $dir";
if (the template of the file is not in the database){
print "Please give me the template so that I can put it in the database";
$dir= <STDIN>;
chomp ($dir);
{code}
Thank you for your help ... if it's possible to help me !!

BalusC -- The line that gives me my NullPointerException is when I call the "DisplayProduct()" method. Its a dumb question, but with NetBeans how do I find out which reference could be null? I'm not very familiar with how NetBeans works with finding out how to debug. Any help you can give me would be greatly appreciated.The IDE is com-plete-ly irrelevant. It's all about the source code.
Do you understand anyway when and why a NullPointerException is been thrown? It is a subclass of RuntimeException and those kind of exceptions are very trival and generally indicate an design/logic/thinking fault in your code.
SomeObject someObject = null; // The someObject reference is null.
someObject.doSomething(); // Invoking a reference which is null would throw NPE.

Calling perl script from PLSQL

Hi All,
I have created Java stored procedure and oracle function to execute the os commnad, this works fine for calling batch scripts but when i used same function to call perl script,
like how we call in batch script
perl <script name> the sql gets hanged.
Is it possible to call perl like this?
or is their any other way to call from plsql
Thanks Chandra

Are you able to run that perl script at DOS command line?
Did you call the perl script directly from the java proc or you put the perl command line in a DOS .BAT scirpt and called that from the java proc?

Recovering Permissions on /usr/lib - pkgchk or perl script?

We have a SUN 280R running solaris 8 which accidently had a 'chmod-R 644 /usr/lib' run on it. The result was that on reboot, the system could not 'execute' or 'find' specific libraries such as ld.so.1 and some files associated with the veritas volume software we have installed on the system. We have been able to chmod most of /usr/lib 755 including ld.so.1. We would like to restore permissions to prevent any system stablity problems. so what is the better method to use here?
1.) do a grep /usr/lib on /var/sadm/install/contents, pull out all the package names with an awk statement and then run them in a loop with pkgchk -fa?
2.) Run a perl script which parses /var/sadm/install/contents, pulls out all the individual files in /usr/lib, and run a chmod <perm> $file on each file name?
Which method would be less destructive? My concern is that running pkgchk on all packages associated with /usr/lib may 'fix' something, or modify something which would prevent the system from coming up.
What key files in /usr/lib would prevent the system from coming back up, if permissions were incorrect? (i.e 644)? Should a chmod <perm> <file> for each file in the contents file for all files in /usr/lib resolve this problem completely?
Any advice would be appreciated.

If you don't already have a current backup, back up all data, then reinstall the OS. You don't need to erase the startup volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it.
