I use a set of common Linux tools for day-to-day sysadmin and computer use, and these can all be configured using dotfiles. Here’s a commented listing of each program’s file:

tmux

The contents of ~/.tmux.conf are as follows:

#Use vi keybindings
setw -g mode-keys vi

#Use ctrl-a as the prefix key
set-option -g prefix C-a
unbind-key C-b
bind-key C-a send-prefix

#Turn on mouse compatibility
set -g mouse on

#Remove the status bar at the bottom
set -g status off

#Set the status colors for when the bar is shown
set-option -g status-style bg=white,fg=black,default
set-window-option -g window-status-current-bg white
set-window-option -g window-status-current-fg black
