How do I source my shell rc file (~/.bashrc, ~/.zshrc, etc) in all tmux panes in all windows in a tm

Time:01-31

Scenario: I edit ~/.zshrc, and I want to source it in all of my tmux panes, in all windows, in a given session. I want to do this with a keybinding, from any pane.

I tried looking at How to send a command to all panes in tmux?, which used setw synchronize-panes on and then ran a tmux ex mode command; but I'd like to run source $HOME/.zshrc, (a shell command), and I'm a little confused as to how to do that.

I'd like it to be a keybinding that I can put into .tmux.conf, so that I only have to press prefix <key_combo> to perform this, and then everything returns to the way it was before I ran this (e.g. I don't have to worry about unsetting any tmux options that the command set)

This would work for you:

# send "source ~/.bashrc<Enter>" to all panes in *current* session
bind  B  run 'panes=`tmux list-panes -s -F "##{pane_id}"`; \
              for pane in $panes; do \
                tmux send -t $pane "source ~/.bashrc" Enter; \
              done'

# send "source ~/.zshrc<Enter>" to all panes in *current* session
bind  Z  run 'panes=`tmux list-panes -s -F "##{pane_id}"`; \
              for pane in $panes; do \
                tmux send -t $pane "source ~/.zshrc" Enter; \
              done'
