(emacs) Directory Tracking:
Shell mode keeps track of `cd', `pushd' and `popd' commands given to
the subshell, in order to keep the Shell buffer's default directory
(*note File Names::) the same as the shell's working directory. It
recognizes these commands by examining lines of input that you send.
If you use aliases for these commands, you can tell Emacs to
recognize them also, by setting the variables `shell-pushd-regexp',
`shell-popd-regexp', and `shell-cd-regexp' to the appropriate regular
expressions (*note Regexps::).
If Emacs gets confused about changes in the working directory of the
subshell, type `M-x dirs'.
