i have server running linux ubuntu 12.04 lts. use user named ubuntu.
recently tried install storm on server , created dedicated user storm purpose.
accidentally because of typo, realized different when switching ubuntu storm.
if switch using following command sudo su storm, runs fine.
however if switch using sudo su - storm, storm program won't started correctly. although both commands have brought me under storm user correctly.
anyone can me explain why? thanks.
t.e.
here's link describing difference between hyphen , no hyphen su. i'm guessing no-dash works because environment variables left alone.
