---------------------------------------------------------------------- (0003342) kre (reporter) - 2016-08-11 17:41 http://austingroupbugs.net/view.php?id=1006#c3342 ---------------------------------------------------------------------- Re note 3341 First, don't even consider treating a zero length PS1 (or PS2 or PS4) as the same as unset - setting the prompt to null is very useful in some circumstances (like when you're scripting and ddon't want junk corrupting the script). Apart from that, that could be a solution, but why? Do you really want to make it unspecified if someone explicitly sets PS1 to its defined default value? To me that makes no sense. Nor would it be anything like traditional for a shell to leave PS1 undefined and then just output '$ ' in that case - while not exactly safe, I have seen scripts that examine the value of PS1 to decide if they're running as root or not - and other scripts that save and restore it. Seems simpler to me to simply make space after '$' stop being unspecified, and have it mean a literal $ followed by space (as it always has.) That is just fix the wording in 2.6 (and I think somewhere else) and be done with it - it doesn't have to be solved in this issue, just because this one was raised first.
