Your counter is wrong. $i + 1 means to treat i as a string and to
append the string "1" to it. If you want to do arithmetic in bash, you
have to put it inside brackets. i = $[i+1].
Btw, an easier way to do a for loop of this sort in bash is to do "for
i in `seq 20`" (notice the backticks).
If you want to do a lot of text manipulation, it may feel more natural
to use Perl (or at least it feels more natural to me).
