Show me the line-count of the newest [by change time] file, 
in the same dir as the executable file:M;
  in a compositional/non*nix syntax might be:
M which | dirname | ls -t | head -1 | cat | wc -l

How is it in this ad hoc *nix mess ?

Also, is 'rename-piping' possible?
eg. instead of:
cp A b.wav; aplay b.wav ; rm b.wav
 aplay `<process file A as fileb.wav would be processed>
?

== TIA.
