Darkcloud TMUX Config


  • A custom theme that matches the one used in darkcloud-vimconfig.
  • A bandwidth monitor showing the current upload and download speed of either eth0 or the device you've set to $NETDEV.
  • Sane defaults and a set of custom key bindings that group similar ideas and make frequently used commands easier to access.
  • Optional support for powerline fonts that looks oh so much better when they're used :).

Darkcloud TMUX Config Theme


  1. Choose either tmux.powerline.conf if powerline fonts are available or tmux.normal.conf if they're not, and install it to /etc/tmux.conf for a system-wide install or ~/.tmux.conf for a local install.
  2. Install bwrate to somewhere available in $PATH and make it executable (ie: install -Dm755 bwrate /usr/local/bin/bwrate)
  3. If your network device isn't named eth0, set $NETDEV to the name of the device you'd like to use somewhere tmux will see it when it runs (ie: echo 'export NETDEV="wlan0"' >> ~/.bashrc)
