Fixing Sublime (subl) CLI in tmux

25 May 2017

This fix is borrowed from here, with some minor adjustments.

brew install reattach-to-user-namespace
echo "set-option -g default-command "reattach-to-user-namespace -l ${SHELL}" \
    | tee -a ~/.byobu/.tmux.conf
byoby kill-server

Then restart your sessions as normal.
