How do I mirror (synchronize) panels in tmux?

I'd like that whatever I do on a panel to be copied on other panels simultaneously.

For example, I'd like to ssh to multiple similar servers and execute identical tasks in all of them simultaneously.

Solution

  • If by panels you mean panes, doing

    <prefix> :setw synchronize-panes on

    will enable the feature you want.

    If you want to turn it off after you are done doing what you want,

    <prefix> :setw synchronize-panes off
