Change userID now can't logon to system
I'm new to this board and so I'd just like to say HI.
I had to change a userID on my redhat linux system and now for some reason I can no longer logon to my system. To change the userID, I had to go into the /etc/passwd file. After that I did that the ownership on my files changed. So I changed them to what they're supposed to be including all of hidden files. What do I do now?
Any advice would be appreciated.
