Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

	OPTIONAL
	ensure pulling is possible via www-data user
	-> sudo -u www-data git pull
	if not add it in visudo
	-> git ALL = (www-data) /usr/bin/git pull

	add ubuntu to www-data group

	-> sudo usermod -aG www-data ubuntu

	bind r source-file ~/.tmux.conf \; display "Reloaded."

	# switch prefix to control-a, unmap b, allow double-a to go through
	set -g prefix C-a
