Indeed, "#!/bin/ [...]" at the beginning of a script allows to use kinda
"debugging" options, too.

IIRC

#!/bin/bash -ex

could be used instead of

#!/bin/bash

set -ex

I just wonder how this could be useful, if it's intended that a command
could either finish with exit status 0 or another status. Actually a
script is a set of rules to interact regarding different exit statuses
("statuses" wow, an English plural that hurts as hell).
