ctfd

Usage

Use ctfd to jump to the most recently cd'd to directory.

This is useful if you need to open multiple shells (e.g. ssh) and work in a hard to find directory. If you only have one shell open, the behavior should be the same as cd -.

Installation

Add these lines to your ~/.bashrc, ~/.profile, or ~/.zshrc file to have it automatically sourced upon login:

function cd { # change the default behavior of cd
  builtin cd "$@" && [ -d ~/.ctfd ] && pwd > ~/.ctfd/lastdir
}

function ctfd {
  [ -d ~/.ctfd ] || echo '~/.ctfd does not exist'
  [ -f ~/.ctfd/lastdir ] && cd $(cat ~/.ctfd/lastdir)
}

Create the ~/.ctfd directory. ctfd will read and write to ~/.ctfd/lastdir to track your working directory.

mkdir ~/.ctfd

Done!

To test your installation, open two shells (if you already have two open shells, don't forget to source ~/.bashrc) and navigate to some directory in the first one. Type ctfd in the second shell and you should be taken to the same directory.
