Currently I have
netcat piping output to
tee which is writing to output.txt with
nc -l -k -p 9100 | tee output.txt
I want to monitor this output, so I'm watching it with
tail -f | egrep -i 'regex' via PuTTY so that I only see relevant bits.
Every now and then I want to clear the output file. The issue arises that if I do
> output.txt and then again try to
tail -f | egrep ... I get no output. If I grep through the file, I get no matches, despite knowing that there should be matches (as
cat output.txt spits out the file properly)
mitch@quartz:~$ grep output.txt -e 'regex' Binary file output.txt matches
While the same command on output.txt before emptying it works fine.
grep think my file is a binary file and it won't properly search. Is there a better way to clear the file?
