Unbuntu default shell

I’m just familiar with csh, but Ubuntu’s default shell is bash. It bothers me that I can’t understand the .bashrc when I set some environment. And when you set come environment such like

setenv sacbin = /usr/local/bin/

, and then it will appear that

"setenv" command not found

I was got mad… So there is a comment from my brother that you can change the default shell, type:


then it will ask you what shell you want, and just type (I want csh.)
