[Solved] How do i deal with values on multiple lines?

Hi,

I have a file which has the contents:
Code:
sh-4.2# pwd
/tmp
sh-4.2# cat servernfiles
server1 /var/tmp/file
server2 /var/tmp/file1

I want to manage each line one after the other. I have this basic script :
Code:
#!/bin/sh

HOST=`cat /tmp/servernfiles | awk '{print $1}'`
CMD=`cat /tmp/servernfiles | awk '{print $2}'`

for i in `cat /tmp/servernfiles`
do
        echo $HOST,$CMD
done

When i run the script, i was expecting to get the output of each line (i.e "server1 /var/tmp/file" followed by the other line "server2 /var/tmp/file1" ) but get this:
Code:
sh-4.2# ./servern
server1 server2,/var/tmp/file /var/tmp/file1
server1 server2,/var/tmp/file /var/tmp/file1
server1 server2,/var/tmp/file /var/tmp/file1
server1 server2,/var/tmp/file /var/tmp/file1

Can anyone please explain why this is or how i can output of each line individually?

To put this into context, im going to develop my script so it can recursively log onto each host and output the /var/tmp/file - but this bit i can do once i can figure out why im getting this first problem

Thanks!
