tmux Configuration

This is a dump of all tmux related configuration and scripts so I can edit them in one place and tangle from a single file.

tmux configuration

Start windows and panes at 1, not 0,

set -g base-index 1
set -g pane-base-index 1

Replace C-b with \,

unbind C-b 
set -g prefix '\'
bind-key '\' send-prefix
set-window-option -g xterm-keys on

Setup key bindings,

bind t source-file ~/.tmux-over-ssh.conf
bind k confirm kill-window
bind K confirm kill-server

bind tab last-window

# window movement / renumbering like in screen's :number
bind-key m command-prompt -p "move window to:"  "swap-window -t '%%'"

Enable UTF-8,

setw -g utf8 on
set -g status-utf8 on

setw -g window-status-current-format "|#I:#W|"

Makes using the scroll wheel automatically switch to copy mode and scroll back the tmux scrollback buffer.

setw -g mode-mouse on

Status bar,

set-option -g  status-interval 1
set-option -g status-right-length 120
set -g status-right '#(~/.tmux-monitor-scripts/cpu.sh)#(~/.tmux-monitor-scripts/cpu_avg_temp.sh)#(~/.tmux-monitor-scripts/disk.sh)#(~/.tmux-monitor-scripts/netspeed eth0)#(~/.tmux-monitor-scripts/battery.sh)#(date +"%a %b %_d %H:%M") | #(hostname)'

Create a new window, swtich to home directory and type tmux-ssh,

neww -n tmux-ssh
send-keys -t tmux-ssh "cd ~/" C-m
send-keys -t tmux-ssh "tmux-ssh "

# pane border
set-option -g pane-border-fg colour235 #base02
set-option -g pane-active-border-fg colour240 #base01
