Loop through the accounts and servers

Shell Programming and Scripting
1

Hi everyone, I am trying to use loop (for loop but can be any loop) which will read from the file (text file) which will have 2 column one for account and another for server which kind of look like this

account1 server1
account2 server2
account3 server1
account4 server1
5 server3
6 server2
7 server2
8 server3
9 server4
10 server4

now here I have to run couple of ksh scripts which i wrote (example tar, stop, start). I have to read from the text file and using those accounts and respective servers I have to login and run those scripts one at a time for all the accounts and respective servers.

If there are 10 accounts they may be in 3 or 4 differnt servers and may not be in sequence as i have writeen down above but thats not a big issue I can put that in some sequence if needed. Write now I am doing it using multiple text files. If I have accounts in 5 servers then I put five text files where I put accounts name and loop through them using resepctive server but I need some way to do that using one text file as I have written before.

I hope I made it clear this time if not i will try to elaborate more later on

I will really appreciate any help
thanks alot
