tmux with synchronized panes.sh

# ZSH Script to open a tmux session for every host passed as CLI argument and synchronizes all the panes.
# Invoke with: ./cluster.zsh user@host1 user@host2 user@host3

#!/bin/zsh

while (( $# != 0 )) {
  tmux splitw "ssh $1"
  tmux select-layout tiled
  shift
}

tmux set-window-option synchronize-panes on


# You can make an alias in your shell as a shortcut to command your servers with ease:

alias cluster_control="tmux new 'exec ./cluster.zsh user@host1 user@host2 user@host3'"

Of course this can be easily adopted to other shells
