Start multiple synchronized SSH connections with Tmux

tmux-ssh

#!/bin/bash

# SSH into multiple hosts with each in their own tmux pane.

if [ "$#" -lt 1 ]; then
        cat >&2 <<-EOM

EOM
        exit 1

for opt; do
        case "$opt" in
                --)
                        shift

                        ;;
                *)
                        hosts+=( "$opt" )
                        shift

for i in "${hosts[@]}"; do

tmux set-window-option synchronize-panes on

exec ssh "$host" $@

Hi, for me it failed to open all panes with the error message 'pane too small' on a decent monitor and 8 panes.

Searching for this revealed:
tmuxinator/tmuxinator#48 (comment)

which suggests to run 'tmux select-layout tiled' after each new pane is spawned and this indeed fixed the problem for me

I pushed it a little bit further to the following:
