I want to log my download speeds using nethogs. I've tried the following:
nethogs -t wlo1 | awk '/firefox/{ print $3}'> speedTest.txt
However, the output file turns out to be empty. I've already assured that I can save to a file using this link. And I've looked at the code in this answer, but it does not exactly do what I want.
I do get DL speed output in my terminal when I try:
nethogs -t wlo1 | awk '/firefox/{ print $3}'
-- EDIT -- With the suggestion below
(nethogs -t wlo1 | awk '/firefox/{ print $3}) &> speedTest.txt
I get the output in the file speedTest.txt:
"Waiting for first packet to arrive (see sourceforge.net bug 1019381)"
which is the standard output from nethogs everytime I run it. The rest of the file is empty.
When I just run nethogs -t wlo1 | awk '/firefox/{ print $3}'
, I get something like
"Waiting for first packet to arrive (see sourceforge.net bug 1019381)"
102.8
248.7
318.2
etc, etc.
