Shell Script Fork Bomb Learning

:() {:|:&};:

Just 13 characters is a bomb, used to look like a simple rote, now also know the point of the fur principle.

:() in bash allow: as a function name

{} function body

:|:&: The function is called first, and then the pipeline calls another new process (called: function),& into the background execution

; Command interval character

: Continue calling itself function

The programmer's thought is unrestrained, but is very forbidden.
