You do not understand it: do not use plain su!

While su was changed, a few years ago or so, to avoid the most serious security issues when using it without -l (or - for short), it is still unwise IMHO. And your experience is proof of it.

oh yes, I didn’t understand at all:O
so you are saying me that I have not to use plain su any more, I have to use su - or su -l in future?
