Chooses random command at your own risk. You can play thorugh running ./trigger.sh and picking mode, or chosing mode individually. In history mode, the command will definitely run, the unceratintly is what command runs. In the other mode, the command has a probability you will give it of running (hence why its called roulette). Good luck!!
You can chose the command that is run. Set a numerator, denominator, and see what fate allows
This will go through a list of potential commands and pick it. I have it set to the name of my bash_aliases, but this can be customized. This can be dangerous so don't really do without a custom file or on a vm
The command that is run is a fork bomb, otherwise the same as custom mode
This is probably the safest one to do, as long as all your files are saved
Obviously don't use this mode unelss your deranged or something. Will call number 5 on this list https://www.techworm.net/2016/10/10-lethal-linux-commands-never-execute.html, and make hard drive permanently unrecoverable. I have not tested this yet for obvious reasons so it might not work who knows.
