How to save the screen output into log file?

Does anyone know this?

If you don't want anything displayed on the console you can just use ./run.sh > log.txt. If you want both output on console and logs only option I think is to use tee.You can pick tee from the RDK rootfs packaged with the release.Note that write to pipe will be buffered and the final logs may not get written to the file. To avoid this you should have below line in your application:

/* Set for line buffering so that even if output is piped buffering does not happen */
  setvbuf(stdout, NULL, _IOLBF, 0); 

Hi Badri,

Thanks a lot for your reply! I don't quite understand where to get tee in DVRRDK. Do you mean that it was packaged in the root filesystem？

Hi Badri,

I find busybox on board. I try to use ./run.sh | busybox tee > log.txt and it works.

Thanks very much!
