Tmux config and status line, easy to use.
To install, run the following from your terminal: (you may want to backup your existing ~/.tmux.conf first)
$ cd
$ git clone https://github.com/t2mahesh/.tmux.git
$ ln -s -f .tmux/.tmux.conf
Open .bash_profile or .zshrc or equivalent and put the following:
export MY_WAN_IP=$(curl --max-time 2 -s ip.me)
Asuming you have used .bash_profile
$ source ~/.bash_profile
If the above is not set, it will get set inside wan-ip.sh at each first run.
Open ~/.tmux/.tmux.conf search for battery.sh and replace it with wan-ip.sh. Save and reload tmux.
