Switching from tcsh to bash?

momerath2003 asks: "With the advent of Mac OS X 10.3 Panther, Apple will switch its default shell from tcsh to bash (in order to conform more to the newer Linux trends). A lot of Mac power users will want to know how to make the switch, especially if they use such tcsh-specific extra files as the login/out scripts in the /usr/share/tcsh/examples directory (they automatically set up some aliases and can automatically read aliases from a specific file, among other things). So, how do we all adapt? What are some ways to emulate the behavior of the example files, and what differences are there between the bash and tcsh shells?"
