Fork bombs----Linux

Now that we're talking about strange code, consider this line:

:() {: |: &};:

It may seem mysterious to you, but it seems to me to be the infamous Bash fork bomb. It will repeatedly start the new Bash shell until your system resources are exhausted and the system crashes.

These operations should not be done on the latest Linux systems. Note that what I'm saying is not supposed to be . I didn't say I couldn't . By correctly setting user permissions, the Linux system can block these destructive behaviors. Usually the user is limited to allocating usable machine memory only. But if you run this line of command (or its variant Bash-fork bomb variant) as the root user, you can still abuse the server repeatedly until the system restarts.
