i=`expr $i + 1`

1. Bourne Shell (/bin/sh) counting?

Some people think that this answer is best thought of as a techie joke...
        count=`expr $count + 1`
              ^    ^      ^ ^ ^  
The spaces a VERY significant, as are the reversed quotes. However it works
and is useful in several of scripts.

This is even funnier:
        count=` echo $count|awk '{print $1 + 1}'`

I'd like to see a neat solution (other than a "increment.c" program).
