Running tmux 1.4 installed from ports on snow-leopard I am unable to use the built in OSX pbcopy command. Outside of tmux: > echo "abc" | pbcopy > echo pbpaste # or using ^v abc But inside of tmux: > echo "123" | pbcopy > echo pbpaste abc I've scoured the man page but can't find any options that might relate to this behaivor. I also can't understand why tmux would mess with shell redirection. Anybody have any clues?
