Screen: continuously record the buffer values and save onto a file
I am asking using the screen command in Ubuntu. I know there is a command that use hardcopy which basically save the buffer onto the file. But how do I continously ask screen to write the output onto a file for me?
If I do the following: python my_program > recorder_this.txt, it won't print the stdout and I can't see the print result. I tried the other method and I am currently running it on AWS, it seems to me that it will cause the machine to freeze. Any help?
amazon-web-services ubuntu ssh gnu-screen

You can record the screen output with the -L option. screen will then create a file called screenlog.0 in the directory where you ran screen (on Ubuntu you will be able to specify the filename if you want).
screen -L
Another solution is to pipe to tee. It will save the output to a file and also print it.
Example
echo "Hello" | tee file_name
