And let's not forget about redirections - any writing/appending inside expansion will make echoing it even more non-trivial. However, the same can be said about M-C-e in command prompt - how is the shell going to know it should not expand this particular part, because it calls a script which appends to / deletes from database? And lets say it deletes not quite what we want? Because we are prototyping on live command. Which makes me say again, if this is such nontrivial, then I choose writing a script. -- Regards, Tomasz Rola -- ** A C programmer asked whether computer had Buddha's nature. ** ** As the answer, master did "rm -rif" on the programmer's home ** ** directory.
