[Help-bash] Adding preceding string to the commands printed when set -v is enabled

[Peng Yu]

Hi,

set -v can print commands automatically. But I feel that it will more
convenient if I can add some preceding string (such as ##### or
=====), so that I can easy tell what are the commands and what are the
output of the commands. Is there a way to do so?

              -v      Print shell input lines as they are read.
