Hi,
We are recently migrated from one server to another linux server.
With server, VAH name also got changed. We have lot shell scripts in the server referring to old VAH.
To make the scripts work we need to change the entries to new VAH , which is lot of work to be done.
I have given a thought for symbolic link. But the challenge is this scripts are not in one location. They are scattered into different directories. We also cronjob with full path.

Can someone help me with an easy way to achive this.

Regards
Sid

What's VAH?

Even if the scripts are not all in the same location, it's not hard to devise a find command that checks if a file is a script and whether it contains the VAH (whatever that is). Then, depending on how the VAH is used, it can be corrected with the text processing tools in Linux.

But perhaps there is a solution with a symbolic link.

I just need to know what is VAH.

Thanks for reply.
VAH is File System. Lets say "/OLD_VAH/scritps" is used as a path in many scripts. We need to change "/OLD_VAH/scritps" to "/NEW_VAH/scritps".

What can be the easiest way?

Thanks
Sid

Perhaps you should post one of the original scripts, (sanitized of course)?

Thank you.

Hi,
This is nothing related to scripting and am sure original script won't help. But i can give u an example below.

#/bin/ksh
##### Load the required Variable ########
/OLD_VAH/scripts/old_variable.sh

###### Some Processing #############


########### Log file ##########

Some Processing >> /OLD_VAH/scripts/log_file.txt


As you can see, the above script call another script with its full path. There are may such type. I have 2 option
1) Search and change the path in all the script
2) Something like Symbolic Link at Global level.

Thanks
Sid

You really need to read the LQ Rules and the "Question Guidelines" link in my posting signature. Don't use text speak, and if you're not going to provide examples, we're not going to be able to help you. We can't guess as to what you're talking about, and you need to ask a clear question[
..which is what you need to do.
...which is too vague for us to guess at. If you mean linking a directory, you CAN do that, but all you're doing is making things on the new system harder to maintain further down the road. Getting your scripts correct is the best thing to do.

Since you don't actually post a script, we can't tell you much.

I believe i have given proper template example. If still it's not clear , you can mention that instead of giving any unproductive reply!
This is probably one line in 1000 line script and has nothing to do with any logic. Still if you think this is an scripting issue ,just by seing the word SCRIPT, then good you gave up!

Thanks for the link! That will definitely help

I *DID* mention it, and TOLD YOU it wasn't clear. And if you had 'given proper template example', we wouldn't have asked.
And if you can't follow the posting guidelines, provide examples, or give us ANYTHING to work with, then there isn't much anyone, on any forum, can do for you.

Again, you can modify your scripts (which, AGAIN, you should do), or create a symbolic link (which SHOULDN'T be done). Pick one. If you're the administrator of a system, have root access to files, and have been asked to modify/change scripts and migrate data, you should have the knowledge you need to modify a script. If you have a lot of files to modify, look into the sed command, and pay particular attention to the "-i" switch.
And what prevented you from doing this search yourself?

I have modified my previous reply.
I was unprofessional, and I apologize for that.
It's not personal.

My apologies too for the counter attack :P
Thanks for you help!

I think the best way is to go with replacing the path in all the scripts.

Thanks
Sid

Two options:

1) Edit all of the scripts and change /OLD_VAH to $VAH_ROOT, then edit the system-wide shell profile to set VAH_ROOT to the VAH location on that system.

2) Symlink /OLD_VAH to /NEW_VAH

#2 is a hack that will get you up and running quickly. #1 is a more permanent and elegant solution that should be implemented once you have time.

Roughly:
The problem is that it might not be correct to replace OLDPATH in some instances.
