Console command shot (Counter-Strike: Global Offensive)

Somehow I got the idea to bind one key for fast switch together with the shot (i.e., shot, switch to knife, switch to last weapon), thought it would be handy for quick shooting with the Deagle. So do not need to measure the timings to squeeze a bunch of keys. Sounds convenient, isn't it? But who knows console command for the shot? What you need to write to the console, so that our hero got shot?
