If I did that & something for bash that used awk | python to do FP arithmetic I might be able to evolve to a more "portable habit/muscle memory" even if Bash never learns FP arithmetic. Solid suggestion, @tux1968. Thanks. { EDIT: 1 down, a dozen to go! lol :-) and I'll go with a(){..} for a)rithmetic not c since I use that for clear. }
