It means the instance of bash running isn't some standalone shell
script, rather you are using bash interactively, as in, with the command
line, in an xterm (or whatever terminal you want).

$PS1 is the variable that defines your prompt. Others gave some
examples.

Looking at the below code, you put it outside of the "interactive"
section, so the alias will not be set unless you are running a
non-interactive bash script. Put it up by the other aliases that are
already there as examples.

I'll leave the code for others to see one more time just for fun.
