# systemd uses 'targets' instead of runlevels.   
# by default, there are two main targets:  
#  
# multi-user.target: analogous to runlevel 3  
# graphical.target: analogous to runlevel 5  
#  
# To view current default target, run:  
# systemctl get-default  
#  
# To set a default target, run:  
# systemctl set-default TARGET.target  

systemctl get-default
