Using tmux both 1.7 and 1.8.

I see \; in tmux.conf files everywhere, but it fails with an error when I add it to mine. Here is an example:

bind -t vi-copy 'y' copy-selection \; run-shell "tmux save-buffer - | curl -d @- localhost:5482"

I get this error:

/Users/user/.tmux.conf:30: usage: bind-key [-cnr] [-t key-table] key command [arguments]

Examples here:

  1. How can I bind multiple tmux commands to one keystroke?

  2. https://superuser.com/questions/562567/tmux-bind-key-and-running-shell-isnt-working

Seems to only happen when using the bind -t option.

The key table bindings (those made with -t) use a different set of commands (only movement and editing); they also do not allow \; to execute multiple commands.

The copy-pipe “mode” command (new in tmux 1.8) looks like it will probably be useful for your particular situation:

bind-key -t vi-copy y copy-pipe "curl -d @- localhost:5482"

You may also need to switch to --data-binary or --data-urlencoded to preserve your data.


I ended up doing it like this using netcat today that is pretty dead simple.


Here is the tmux.conf:

bind -t vi-copy 'v' begin-selection
bind -t vi-copy 'y' copy-pipe 'nc localhost 5682'
bind p run-shell 'nc localhost 5683; nc localhost 5683 | tmux load-buffer -' \; paste-buffer
bind p run-shell 'nc localhost 5683; nc localhost 5683

Works with the mouse too in 1.8
