tmux command

I’ve started using tmux instead of screen lately. My version of screen (no longer maintained) doesn’t do vertical window splits where tmux does.

Just like screen, I use backtick as my C-a. Backtick-c will create a new window. Backtick-d will disconnect the sessions. The command “tmux attach” will re-attach to my sessions and it remembers all my window splits which I never could do in screen.

Here is my current .tmux.conf cobbled together from google searches.

# Set option key
set-option -g prefix `
# Set status bar
set -g status-bg black
set -g status-fg white
set -g status-left "#[fg=green]#H"
unbind % # Remove default binding since were replacing
bind | split-window -h
bind - split-window -v
#set-option -g mouse-select-pane on
bind ` send-keys `
bind e send-keys "smitty etherchannel"
bind a send-keys "netstat -v | grep -i activ"
bind s send-keys "stty erase ^?"
# basic settings

# copy mode to escape key
unbind [
bind Escape copy-mode
set-option -g mouse-select-pane off
# window title

set-option -g set-titles-string '#S:#I.#P #W' # window number,program name,active (or not)

set-option -g status-justify right
set-option -g status-bg black
set-option -g status-fg cyan
set-option -g status-interval 5
set-option -g status-left-length 30
set-option -g status-left '#[fg=magenta]> #[fg=blue,bold]#T#[default]'
set-option -g status-right '#[fg=cyan]>> #[fg=blue,bold]###S #[fg=magenta]%R %m-%d#(acpi | cut -d ',' -f 2)#[default]'
set-option -g visual-activity on
set-window-option -g monitor-activity on
set-window-option -g window-status-current-fg white
# clock
set-window-option -g clock-mode-colour cyan
set-window-option -g clock-mode-style 24</code>
# bind keys for synchronize-panes
bind -n C-x setw synchronize-panes on
bind -n M-x setw synchronize-panes off

And this is what one of my tmux screens look like: –

Update :

    backtick + left/right/up/down will move to different panes
    backtick + 0/1/2/etc will move to different screens
    backtick + | will create a vertical split pane
    backtick + – will create a horizontal split pane
    Control-x will turn pane sync on to allow input to all panes at the same time
    Alt-x will turn pane sync off
