Emacsでのapellの設定

(setq ispell-program-name "/usr/local/bin/aspell")

tmux内からopen(macOS)を使う

brew update
brew install reattach-to-user-namespace
brew upgrade reattach-to-user-namespace
echo "set -g default-command \"reattach-to-user-namespace -l ${SHELL}\"" >> ~/.tmux.conf

Unable to use 'open' command in OSX tmux
