su - root isn't acting right
 

Using Fedora, and when I type in su - root, and enter my password, it returns the following:

-bash-4.2#

No idea how to fix this. Thanks for any help!

You only need to do "su -", not "su - root". The root is implied.

Anyway, what's the problem? root often has a different prompt than normal users, looks normal to me.

What is wrong with it?

What you see is the default Bash prompt for the root user (indicated by the #-character, an unprivileged user by default has the prompt ending with $).
Seems to be OK to me.

Wasn't like that before, no idea why it changed, or how I can change it back.

Change it back to what? What are you expecting it to look like?

You can use the environment variable PS1 to change your prompt to whatever you like.
