(For reference, we’re talking about the Resume feature of Mac OS X Lion 10.7 and later.)
Terminal automatically restores the working directory if you’re using the default shell, bash. If you’re using some other shell, you’ll need to adapt the code in
/etc/bashrc to send an escape sequence to communicate the working directory to Terminal so it can restore the directory later for Resume. If you’re using zsh, see my answer to Resume Zsh-Terminal (OS X Lion), in which I include the appropriate code for zsh.
If you have a custom
~/.bashrc you may need to ensure that you’re not undoing the default behavior by modifying
/etc/bashrc’s customizations. In particular, it sets the
PROMPT_COMMAND environment variable to send the escape sequence at each prompt. If you customize that variable, you’ll need to prefix or append your code to the current value, e.g.:
PROMPT_COMMAND="<your code here>;$PROMPT_COMMAND"
~/.bash_profile should execute
if [ -f ~/.bashrc ]; then
