"seq" is more common than bash

  for i in `seq 1 5`; do

but still not available everywhere.  On this note, I see the use of
$[expr] which is definitely less portable than $((expr)), but neither of
which are mandated.  I suppose the arithmetic could be done with "bc",
which at least is part of POSIX.  Or with python -c ...
