看到一个有趣的东西， 大家来看看
我没有测试， 谁有机会 测试一下：
大家 也可以想想 解决办法哈， 其实解决的办法还是很简单的。。
------------
fork bomd:

the code is:
:(){ :|:& };:
This is a bash function. It gets called recursively (recursive function). This is most horrible code for any Unix / Linux box. It is often used by sys admin to test user processes limitations (Linux process limits can be configured via /etc/security/limits.conf and PAM).

Once a successful fork bomb has been activated in a system it may not be possible to resume normal operation without rebooting, as the only solution to a fork bomb is to destroy all instances of it.


Understanding :(){ :|:& };: fork() bomb code

:() - It is a function name. It accepts no arguments at all. Generally, bash function is defined as follows:

foo(){
arg1=$1
echo ''
#do_something on $arg argument
}

fork() bomb is defined as follows:

:(){
:|:&
};:

:|: - Next it call itself using programming technique called recursion and pipes the output to another call of the function ‘:’. The worst part is function get called two times to bomb your system.

& - Puts the function call in the background so child cannot die at all and start eating system resources.

; - Terminate the function definition

: - Call (run) the function aka set the fork() bomb.

Here is more human readable code:

bomb() {
bomb | bomb &
}; bomb

Properly configured Linux / UNIX box should not go down when fork() bomb sets off.

有些没有看懂：如这句
& - Puts the function call in the background so child cannot die at all and start eating system resources.

原来没有看过哈，，
蝈蝈 都试过了 强大
看来效果 很明显，，，

你有办法  解决解决吗？
