I have no idea if anyone else does this, but I use tmux a lot for different projects. I usually have vim in one tab, logs in another, and tests in another. However, each tab I open I need to cd into the same directory. As such I came up with this helper for zsh. Every time I change a directory it records it. When I start a new session (new tmux or iTerm tab) it goes straight to that directory:

    # record directory in ~/.lastpwd
    record_pwd() {
      pwd > ~/.lastpwd
    }
    chpwd_functions=(record_pwd)
    
    # go to last directory when opening a new shell
    if [[ -d `cat ~/.lastpwd` ]]; then
      cd `cat ~/.lastpwd`
    fi

For other shells that don't have something like chpwd_functions you could just alias cd.
