I use tmux to develop, with two panes: one to edit the code, and one to compile it. I need to switch pane very often to launch the compile command (say "mvn install").
How can I bind a key (say "Ctrl+B C") to launch that specific command in the other pane (or without any pane at all)?

The right answer to this question is: use bind-key, e.g.:

tmux bind-key "$KEY" run-shell "/path/to/script.sh"

where KEY=C in your case.

  • Thanks. It's not clear to me where the command will be run? In which pane will be the output?

    This should be the accepted answer. meuh's answer works but it simulates real human interaction, thus results in printing the command into the terminal pane.

C-b c already has a standard binding which it might be wise to leave unchanged. Choosing another character, eg C-b C you can setup a binding in your ~/.tmux.conf file as follows:

bind C send-keys -t.- 'mvn install' Enter

The -t.- means "the other pane". Enter stands for the key of that name, i.e. the newline at the end of the command.

  • Thanks for the solution. However, I learned that it also prints the command to the terminal pane due.
