Write output from netcat to a file

Question

I'm currently trying to write a scan port result to a text file

Here is the command I tried to use:

nc -vv -z localhost 1-80 > file.txt

This doesn't work (that is, the error messages from nc don't end up in file.txt), but when I type: nc -vv -z localhost 80 > file.txt It works.

I already know that there is an output but I can't write that in a file.

I heard that netcat output was stderr I tried '2>' too and even '2>&1' but it's still doesn't work — Lapinou, Mar 29 '15 at 16:16
What do you mean by "This doesn't work"? Do you mean that you cannot get the error messages from nc into file.txt? — roaima, Mar 29 '15 at 16:17

You need to direct both stderr and stdout into the file:

nc -vv -z localhost 1-80 > file.txt 2>&1
