[bug] [docs] netcat / nc is not working as described and with wrong help text.

[eabase]

I've been experimenting using the toybox nc to try to connect from my Windows Host PC, to the Android Studio AVD instance. None of the commands suggested works. I can see the text in the terminal, but the actual commands never execute.

# Terminal-1 in AVD:
nc -4 -s 127.0.0.1 -p 8888 -L sh -l

# response from below commands 
: inaccessible or not found
: inaccessible or not found


# Terminal-2 in Windows-11, windows Terminal + powershell, and using nmap ncat
adb forward tcp:8888 tcp:8888

ncat -v -4 -C 127.0.0.1 8888
Ncat: Version 7.98 ( https://nmap.org/ncat )
Ncat: Connected to 127.0.0.1:8888
