Shell Programming and Scripting

do you know a simple script on how to log remotely to a server where the user will only input the IP address? then it will look for a file where it contains all the IP addresses then it will ssh to it?

sample:
echo "pls input the server you wanted to login remote"
----in here user will input an IP address or the hostname ---

if the user will input say 'cash01' (hostname) it will look for a file called servers.txt on the current directory Servers.txt contains all the hostname of multiple servers. It it contains "cash01" it will ssh remotely to it. if there's no match, it will say no matching server found.

pls help

What did you try so far?
A solution in bash could look like this:

Code:

echo "Please enter server IP or name" && read server && grep $server /path/to/Servers.txt >/dev/null && ssh $server || echo "No matching server found"
