this is a bit of a beginners question, but I hope that's okay. What I
want is something very simple: Have cd echo the current directory each
time it is called. I know how to make a proper alias for that purpose
in csh and tcsh. But I have no clue how to do that in bourne shell
variants and others (sh, bash, ksh, zsh etc). So, if you know how,
please drop me a one-liner.
