i came up the following script when i was first learning unix, which does
the same thing (convert all the entries in the current directory to
lowercase).  it took me forever to figure out, but i became quite familiar
with the system during the process..

## lowerdir
ls > tmp1
tr A-Z a-z < tmp1 > tmp2
paste tmp1 tmp2 > tmp3
ed tmp3 <<!
g/^/s//mv -i /
w
q
!
sh -x tmp3
rm -f tmp1 tmp2 tmp3
