put output from screen command into txt file-CodePudding

I am running the command sudo screen /dev/ttyUSB0 115200 am trying to put its output into a .txt file.

I have already tried:

sudo screen /dev/ttyUSB0 115200 >> output.txt
sudo screen /dev/ttyUSB0 115200 > output.txt
sudo screen /dev/ttyUSB0 115200 | output.txt

But both options didn't work.

Please help.

CodePudding user response：

check the manual page for screen command

man screen

-L tells screen to turn on automatic output logging for the windows.

if you're using screen to run the command on background, like ping www.google.com

then you just need to execute like this:

ping www.google.com >output.txt 2>&1 &
