Shell Programming and Scripting

The situation is like this.

If I need to know the parameters of all the unix servers connected to a common network, is it possible to get all the parameter details of all the system with the help of a script written in one server??

Can a script be written like that ?

Let me give some more insight in to this.

Say, I login to a system, from that system I write a script to login to other servers by doing SSH to IP addresses of those servers stored in a file, execute the commands in that server environment and return the parameter details to the parent server from where I executed the script initially.

In simple words, If I include a SSH command and IP addresss in a script, is it possible for the remaining commands to be executed in the new server environment (to which I 'SSH'ed to.. )rather than in the same server where I wrote the script.

Your ideas are most welcome.

Code:

command="hostname; vmstat"
while read ipaddress 
do
     ssh me@"$ipaddress" "$command"
done < ip_file > output_of_commands

Is this what you mean?
where ip_file looks lile

Code:

20.20.20.10 
20.20.20.11

thanks for your reply..

What I need is like, it should execute the commands in another server ,get the output of the commands and return back to the server from where I executed the script initially , so that I can do the same for other servers. Can that output be directed or appended back to a single file in the first server which I can use to compare the parameters of all the set of servers in that network.

Moreover, where do we get to enter the password in the above script.

I hope I made it clear.

You can use expect or run as per the script above and store the output in a file and then ftp the file to the server
