Shell Programming and Scripting

Hi,

Here is my code to send read.txt to three servers.

Code:

col="prd167.mybank.com prd168.mybank.com bsprd169.mybank.com"
set -A look $col
for IndixList in ${look[@]};
do
scp /tmp/read.txt admin@$IndixList:/tmp
done

This works and all the 3 servers gets the read.txt file.

However, after the thrid server's scp command is procesed it asks for the password. We login with user1 / password and then switch to admin user using the command sudo su - admin which does not ask for any password nor do we know off any password for admin user.

My job's done !! but i wish to somehow come out of the for loop so the rest of the unix script gets executed.

Your issue is not with the bit of code you submitted, but elsewhere in your script so we cant help you...

Have a look at ~/.netrc.
Either you miss the 'credentials' (uid/pw) of the 3rd server there, or have supplied them elsewhere for the first 2 servers.

Hope this helps

It has to do with the for loop scp cmd where it prompts for the password.

See the snapshot, it shows where it freezes and waits for the password when the file is already transfered.

So post #3 gives you the answer...
You need to do the same as what was done for the 2 other servers... ( public key exchange seems...)

The keys cannot be set due to policies in place. The configuration is exactly the same on all three servers. If it was the issue with the third and last server, then I reduced the server list to only two.

Now it is asking password for the second server !!

Let me tell you the read.txt file does get copied to all the servers. All i wish is to get rid of the final server (whichever it be) password prompt and somehow exit the forloop for the remaining script to be executed.

A bit hard to believe. And, btw, 'twas readdate.txt in your screenshot. Please post a log of the entire session. Are you sure there's no <carriage return> char in there somewhere?
