Configuring tmux

Edit $HOME/.tmux.conf to display the program's output in status-left or status-right. For example:

set -g status-interval 2
set -g status-left "#S #(tmux-mem-cpu 2 'fg=blue,bg=black,bright')#[default]"

Note that the first argument to tmux-mem-cpu should be the same number of seconds that status-interval is set at.

An optional second argument is the default text foreground color.
