Send same command across all window panes

You can send the same command to all window panes

 ctrl +b : set-window-option synchronize-panes on

to turn off synchronzie

ctrl +b :  set-window-option synchronize-panes off

Configure tmux.conf file

set -g mouse on
set-window-option -g clock-mode-colour green #green
bind-key -n F1 set-window-option synchronize-panes on
bind-key -n F2 set-window-option synchronize-panes off

incase you get dotted lines saying (attached from a smaller client)

In this case, its because there are different attachments to the tmux session . we just need to detach from other screens

ctrl +b shift +d  

the above will display all the attachments. Just choose and detach using

ctrl + d

Tmux conf that I use

# save as ~/.tmux.conf
# C-b is not acceptable -- Vim uses it
set-option -g prefix `
bind-key ` last-window

# Start numbering at 1
set -g base-index 1

# Allows for faster key repetition
set -s escape-time 0

# Set status bar
set -g status-bg black
set -g status-fg white
set -g status-left ""
set -g status-right "#[fg=green]#H"

# Rather than constraining window size to the maximum size of any client
# connected to the *session*, constrain window size to the maximum size of any
# client connected to *that window*. Much more reasonable.
setw -g aggressive-resize on

# Allows us to use C-a a <command> to send commands to a TMUX session inside
# another TMUX session
bind-key a send-prefix

# Activity monitoring
setw -g monitor-activity on
set -g visual-activity on

# Example of using a shell command in the status line
set -g status-right "#[fg=yellow]#(uptime | cut -d ',' -f 2-)"

# Highlight active window
set-window-option -g window-status-current-bg red

# Set mode to vi
set-window-option -g mode-keys vi

# scroll on
set -g mouse on

set-window-option -g clock-mode-colour green #green

#synchronize panes
bind-key -n F1 set-window-option synchronize-panes on
