Okay, not sure if it can be done, I would think it could be done and I'm just having a hard time with it.

Right now, it seems to run through the first function, but once it gets to the second function it doesn't run through it. To test it I commented out the first function call and it runs just fine, so both function call's work and the script does what it's intended to do, only when I try to call the function twice is where I get the issue.
in the port list files it's just a flat file like the following:
You have an exit command at the end of your function so I don't see how you'd even be able to run though it twice but that's neither here nor there. Try adding the following line:
That's a typo when I took out the actual IP's and server names. In the actual code they have the same number of arguments.

Taking the exit out and putting it after the function calls worked.
I originally created this w/o it being a function, and decided it'd be easier for me to use multiple function calls inside a single script, rather than passing multiple parameters from outside, and forgot to take out the exit line.
exit will exit the script even it's in function. If you need to make "exit" in function = interrupt function, then use return in function like you use exit.
function some
{
[ "$#" -lt 2 ] && return 1
do_something
# you can say return, but it has done automatic also
}
#main
# calling function = calling command = calling alias = ...
some arg1
$stat=$? # look exit code of some, in this case function return code
echo "some exit status $stat"
