Need Shell Script Help

Ashok_20 — Sat, 05 Mar 2005 15:49:21 GMT

Hi,

I need some Shell Script Help. I want to have a shell script on one m/c, whose contents will be as follows:

# -- M/c1 scripts
.//test.env
.//test1.sh
rlogin M/c2
.//test1.env
./PATH_NAME>/test1.sh
exit
-- Comback to M/c1 and execute some more scripts
When I am trying to execute a test scripts, It comes till rlogin m/c2. But stays at the prompt. does not proceed to the next setup commands.

Am I missing something?

Please help me in writing a shell script and finding some good site about learning Shell Scripts.

What do you want rlogin to do? Do you want to execute test1.env and test1.sh on the remote host? If so it's not the way to do it. rlogin just waits for input from stdin, it's interactive program.

I believe you need remsh or if you have ssh use ssh.

If I understood you right, on the remote box you must create .rhosts file in the user home directory and write there the ip and the user that can execute the commands, then you can use remsh without getting adked about password.

For example, you have two hosts:
111.111.111.111
111.111.111.222

you want user alex to execute scripts on the remote box with user danny.
Login into remote box and in the home directory of danny create file .rhosts and put in it:
111.111.111.111 alex

Now on 111.111.111.111 you can do:
remsh -l danny 111.111.111.222 "ls -l /tmp"

(usage: remsh -l )

For more details you can man remsh.
But I suggest to use ssh. Easier and secure.

3 host sollution with ssh!
Install keys for ssh on node 2 and 3 the client servers :-)

host1 (master script host):
#!/usr/bin/ksh
scp .//test.env user@host2:.//
scp .//test.env user@host3:.//
ssh user@host2 -c ".//test.env"
ssh user@host3 -c ".//test.env"
ssh user@host2 -c "rm .//test.env"
ssh user@host3 -c "rm .//test.env"

You could put the commands together with a ';' as sepperation, but for the ex. this is better.

Hope it helps!

rlogin is the problem. It is an interactive command so the shell script can't proceed. If you need to run remote commands, use remsh or if you have ssh imstalled, it is much preferred ove remsh.

Sir,

Thanks for Your Reply. I tried using the following Command and get the following error.

ssh applmgr@bdfdb2 -c '. /oracle/FAHRIS/fahrisora/8.0.6/FAHRIS_bdfdb2.env'

Error:

Unknown cipher type '. /oracle/FAHRIS/fahrisora/8.0.6/FAHRIS_bdfdb2.env'

I think it has something to do with keys. Did you copy key from the server into authorized_keys file on the remote host?

Hi Oliver,

I will be glad to assign Points. But where and how to assign points ?

Re: Need Shell Script Help

Alex Lavrov. — Fri, 11 Mar 2005 18:06:25 GMT

At the right corner of each message box you can see a dropdown. Currently it says "unassigned", but you can change it to the number of points, according to how this answer helped you (if it helped) and then click "Submit".

That's all :)
