Question Counting names
Hey,

I need to count the ammout of different names that are given by an application in this form:

Name1
Name2
Name3
.......

now I could use:

Code:
  
for online in `$NAMESBIN | tr -d ' '`; do
    USERSON="$( expr "$USERSON" \+ "1" )"
done

however if there was twice John it would get counted as two and not one.

So basically:

John
Britney
David
Paul
John

would result 5 while it's 4 different names.

How to make it properly ?
