Thanks CHAZELAS!
Very good explanation.

I like read his posts, excelent for learning about most unixes
peculiarities.
My focus will never be portability and my environments are always
under my control.
My universe is very limited and pure shell is always my start point.
I don't see problems with escaped "*" in standard input in that case,
for bash at lest.
For small files I think the shell will be more efficient than the use
of a call to an external tool that isn't in the cache.
