Hi,

Try using Cron. Check this out: http://www.aota.net/Script_Installation_Tips/cronhelp.php3

Hi,

Do you want to write startup script ? or any shell script to automate something ? "Batch script" is a windoze word.

Hi,
http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=1034456 covers the difference between .bat and .sh.

For help on how to write shell script:
http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=940583

or at the simplest level:
create a file,calling it a.sh, which contains:

#!/usr/bin/sh
ls

then chmod 700 a.sh
to execute './a.sh'
which will list your directory

Hi amonamon,

If you're talking about writing a shell script to execute different programs successively, here's a general template:

#!/usr/bin/sh
/
/
exit 0

So if you wanted to write a script that:
1) lists the contents of /var/tmp, and then
2) reports system uptime,
you could write the following to a file:

#!/usr/bin/sh
/usr/bin/ls /var/tmp
/usr/bin/uptime
exit 0

Let's say you wrote this block to /home/user1/scripts/script01.sh. To be able to execute script01.sh, you must make sure it has execute permission:

# cd ~user1/scripts
# ls -l script01.sh
-rw-r--r-- 1 root root 0 Jul 11 08:21 script01.sh
# chmod u+x script01.sh
# ls -l script01.sh
-rwxr--r-- 1 root root 0 Jul 11 08:21 script01.sh

Then to execute it:
# ./script01.sh

Here's an execellent user's guide to shells under HP-UX:

http://docs.hp.com/en/B2355-90046/

If you're not able to execute some pre-existing scripts, make sure they have execute permission, and that you're logged in as a user having sufficient privileges to run them.

I think noone understands me..

On my windows machine XP machine...I want to create file file1.bat

On that file I want something like this:

telenet 123.456.798.123
root
root
here command to execute script on UNIX machine ./script

exit

so I need batch script on windows...

Re: batch script to execute unix command?? how??

Peter Godron — Tue, 11 Jul 2006 07:52:03 GMT

The batch job will not be able to supply the pasword at the prompt, so you will need a telnet client.

This is the first time you menioned the windows OS!

The windows telnet cannot be scripted, you need another "telnet-able" application or any windows versions of unix like applications for this.
Best solution will be an ssh client.

amonamon,

You've got many options. One is to install OpenSSH for Windows:

http://sshwindows.sourceforge.net/

Then generate a public/private key for the Windows client, and copy the public key to the HP-UX server (this will allow you to log in without a password):

http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=1005579

Then you can do something like:

C:\> ssh hpux_server command

This line could be added to a Windows batch file, if so desired.

A second option is to create an HP-UX user for the express purpose of running a script. Then add the path to the script to that user's ~/.profile (followed by "exit"), and log in as that user from the Windows client via Telnet or SSH. As soon as you login as that special user, the script will run, after which point the session will close.

OK thanks for answer so it is imposible to write batch script and supply pass. for remote UNIX machine...

I did not know that it is imposible..but thanks for answer..

I have 2 ideas,

1) You can script a windows batch file
to do an ftp to put a file on unix.

Well this gives rise to a few creative
possibilities.

You could on unix run a bacground job
that checks every 20 seconds for a file and if newer then executes your unix script.

This would work and is quite simple to implement.

2) You could also install nfs client with Samba this way you can run executable or batch on windows and trigger something on Unix platform. This is more heavy to configure.
We use this for our Oracle tools which are Âµ
windows based but need Unix as well.

Good luck:))

hi amonamon,

You need to download Expect for Windows, it's a great tool for automating Unix hosts from your Windows client...get it from here:

Another option is a remote exec application running on your Windows machine.
Google search for REXEC and REXECD for windows.
There are many remote exec products for windows available and some you will find as freeware.

Disclaimer:
Remote exec is a severe security risk. If the machines in question are accessible only in an internal ip environment, rexec is a viable option. If the machine ip is open to the world this is not a good option.

After all this discussion on a batch script, I would like to simply suggest using the "at" command.

"at" is a one-shot run-in-the-future batch facility that is usually available to non-root users.

Hello All,

Can anyone please tell me how to configure the "OpenSSH" software so that it does not prompt for a password?

The scenario is that I want to shutdown HP-UX machines from a Windows machine. I want to create a batch file in windows that will run shutdown scripts in all the servers one by one. This I want to do without any human intervention.

I have installed "OpenSSH" on my windows machine and executed 'ssh root@'. Initially it showed an RSA key. I made a text file in windows and put the key in it and then copied it to the '/home/root/.ssh' directory on my server that is running HP-UX. It does not show the key when I run 'ssh root@' on windows, but it prompts for a password, for which human intervention is required.

Please let me know what step I am missing.

OldSchool — Tue, 22 Aug 2006 09:14:11 GMT

also, look at the "r" commands in Windows. may have to be added, it been a while since I've done this.

remsh, rexec .....

then in bat1.bat

remsh /path/to/script

might get the job done....

You also might have better luck posting in a Windows forum as well

System Administrator:
Thanks for the reply. REXEC also prompts for a password and I can't find any option to provide it with a password. Anywayz... shifting my question to a new thread.

Steven E. Protter:
Thanks for the reminder. I thought the same discussion could remain in the same thread. Anywayz, posting my query in a new thread :)
