How to save an output of airodump-ng to a file?

Question

I've tried to get a file from airodump-ng via redirecting a output stream via:

airodump-ng mon0 2>&1 | tee file.txt

but this appends to a file rather than rewrites it. So after that I've tried to redirect an output to other output stream via a fifo pipeline:

First terminal:

mkfifo fifo1
echo "while [ 1 ]; do cat ~/fifo1 2>&1 | tee file.txt done" > readfifo.sh
chmod +x readfifo.h
xterm -e readfifo.sh

Second terminal:

airodump-ng mon0 2>&1 > fifo1

And in the result we have an appending file.txt, but why ? How to have only the output of a terminal in the file, but not append to it ? Is it possible to filter an output of airodump-ng while writeting to a file ?

Answer 1

Check

man airodump-ng.

You want the -w option.

airodump-ng -w myOutput --output-format csv mon0

Generates a .csv file of the screendump with the output from airodump-ng one line per station.
