On OS X, if I use tmux (or more usually, wemux for pairing) then I end up with oddly named windows like this:

This is because I’ve followed the awesome instructions from Dr Bunsen’s Text Triumvirate and in order to have the tmux and system (OS X) clipboards interacting, it requires a hack called reattach-to-user-namespace which proxies the running of zsh in tmux.

One quick way to get around this and save time renaming my tmux windows, was to use autoenv and add a file named .env to projects with content similar to:

tmux rename-window "project-name"

This is piling hacks on top of hacks, but at least it saves a bit of time for frequently visited directories.
