Hi, all. thanks for your help last time. I have another question, could you
help me ?
I read bash's changelog. And it says in version 4.2, posix parsing changes to
allow '! time command' and multiple consecutive instance of '!'(which toggle)
and 'time'(which have no cumulative effect).
In bash-4.1 we also can use '! time command', just it outputs different words with
bash-4.2. And I don't understand "multiple consecutive instance of '!'(which
toggle) and 'time'(which have no cumulative effect)". What actually does it want to
do?
