help understanding ksh script


So there is a segment of a ksh script on our server that does this:

for LINE in `cat ${TMPFILE}`
do
enable ${LINE}
((COUNT+=1))
done

I know what the "for/do" does, but what does the "COUNT+=1" do? And yes, I am new to linux and scripting.

Thanks

It simply adds 1 to the current value of COUNT. In other words it increments the value of COUNT by 1 at each loop. There are similar operators, like -= or /=. Here is the full list.
