missing bash files
 

My bash prompt has changed from coma @localhost blah blah to "bash-2.05b$" . This wouldn't be a problem except for the fact that it no longer shows colors (so I can't tell whether something is a file or directory) and all of my aliases are gone. :(
I ran ls -a to check my alias file and it's gone. The only bash file I have is .bash_history. Does anyone know what happened or if there's anyway to get these files back? tia.

edit: I just checked the .bash_history file and the last rm command was rm -r ./ Mail. (with the space)

That would explain why everything is gone. You should be able to copy the .bash* files from the skel directory:
cp /etc/skel/.bash_* /home/USER/
chown USER.USER /home/USER/.bash_*

Thanks! :D
