How to pipe to grep play (sox) output?












1















It seems a silly situation: I have this command:



play -n synth 25:00 pinknoise


I don't want to silent completely the output (-q option), just one part (the header). grep won't work. The output doesn't seems stdout nor stdin. I'm not sure how that kind of updated output (like in npm install ... works).



How can I grep just one part of the output?

          You can grep the output if you pipe stderr as well, e.g.:



          $ play -n synth 25:00 pinknoise |& grep File
          File Size: 2.52G
