Need a Console Command

Anyone knowing what is the console command that enables/disables/toggles if the HUD shows? Thanks alot!

cl_drawhud 0 disables hud
cl_drawhud 1 enables hud

Thanks for the answer!

Also, how do I turn off the “Mingebag killed Combine Soldier” message, in the top-right of the screen? Thanks alot for the help!
