How to completely remove control characters from a file?

Question

linux

Good afternoon. I write the result of the program execution to a file with the following command sudo trafshow -i enp0s3 > file.txt

The output is the following:

[?1049h [22;0;0t [1;24r (B [m [4l [?7h [39;49m [39;49m (B [m [H [2JSource [1;27HDestination [1;53HProtocol Size [75GCPS

Found on the Internet how to convert to a readable form, the following command

tr -s "[\027]" "\n" < /1.txt |\
sed -n '/Source/,${
     s/\(^.*\).$/\1/
     /^.*qqqqqqqq.*$/d
     s/^[a-zA-Z]\(.*\)/\1/
     s/^[0-9][a-zA-Z]\(.*\)/\1/
     / [ ]*$/s/ [ ]*$//
     /^.......................*/p
     }' > /2.txt

I get the following

But for some reason did not completely remove the characters. I highlighted in bold.
Help fix this. Not very strong on Linux

Answer 1

sudo iftop -PtNn -i enp3s0 > file.txt
or netflow sensor + netflow collector if you need to collect traffic data on an ongoing basis (for example, fprobe + nfdump)
