An alias is only good at the level at which it is invoked or for children
of that level. It does NOT propagate to parents of that level. thus if you
run the script it is that script and its children for which the alias
applies. It does NOT apply to the parent level which called the script.
When you source it ( also done with
source yourscript.sh
)the commands in that file are run by the parent level, and thus apply at
that level.
