Console commands
- Games running on the Source engine can utilize Source Engine Console Commands for various tasks.[1]
Creating your own CFG (to run multiple console commands together)
A CFG is a file that contains a list of commands that when run will attempt to execute them all
Open up a text editor such as notepad and type in all the commands you want separating each with a ;
When done save the file as filename.cfg in <path-to-game>\left4dead\cfg
. To run the cfg file, open the console during the game and type in exec filename.cfg
If you want the CFG file to run automatically, name it autoexec.cfg
.
