My tmux settings explained
I am using tmux for almost 2 years now. I was using and was a big fan of screen before that. But screen was replaced by tmux from the moment one of my colleague introduced me to a more actively developed tmux.
Here I am documenting my Tmux configuration. Full configuration file is stored at Github
#Use screen key combination
unbind C-b
set -g prefix C-a
bind C-a send-prefix
Above settings will replace default prefix for tmux from Ctrl+b or CMD+b to Ctrl+a or CMD+a. It also binds Ctrl+a+Ctrl+a or CMD+a+CMD+a to send prefix to multiplexer running under tmux such as screen.
#Some easy key combination to Split window
bind | split-window -h
bind - split-window -v
Now its time to change the keyboard short cut to Prefix + | for vertical split and Prefix + - for horizontal split.
#Easily reload configuration
bind r source-file ~/.tmux.conf \; display "Reloaded!!!"
Easily reload the configuration file using Prefix+r
#Change starting window index to 1 from 0
set -g base-index 1
#Monitor activity in windows
setw -g monitor-activity on
set -g visual-activity on
Change the window index from 0 to 1 and keep monitor activity on each window.
# status bar colors
set -g status-fg white
set -g status-bg black
set -g status-left-length 40
set -g status-left "#[fg=green][#[fg=yellow]#S #[bg=black,fg=cyan]Win: #[fg=yellow]#I #[fg=cyan]Pane: #[fg=yellow]#P#[fg=green]]"
set -g status-right "#[fg=green][#[fg=cyan]%d %b %R#[fg=green]]"
## window list options
setw -g window-status-fg cyan
setw -g window-status-bg default
setw -g window-status-attr dim
setw -g window-status-current-fg white
setw -g window-status-current-bg red
setw -g window-status-current-attr bright
setw -g automatic-rename on
set-window-option -g window-status-format '#[fg=green][#[fg=cyan,dim]#I#[fg=blue]:#[default]#W#[fg=grey,dim]#F#[fg=green]]'
set-window-option -g window-status-current-format '#[bg=red,fg=cyan,bold][#I#[bg=red,fg=cyan]:#[fg=colour230]#W#[fg=dim]#F#[bg=red,fg=cyan]]'
Above settings will format the status bar at bottom. Below screenshot shows the left side of statusbar.
Above status bar is from a tmux session with name dev.
tmux new -s dev
As you can see left side of status bar shows tmux session name, number of windows, number of panes and window list. You can see that window index start from 1 instead of default zero and active window background is red.
Right side of the statusbar is set to show the the date.
set -g status-right "#[fg=green][#[fg=cyan]%d %b %R#[fg=green]]"
Result will look like :
Thats all about my Tmux settings :)
