It look like duplicate of this Save the console.log in Chrome to a file ,but Accepted answer doesn't seem to work anymore and rest are third party plugin. Also question is very old. Asking for any update.
I tried using above solution, but console-debug log doesn't print console.log
I am using chromium 40 on IMX6Q Board with Linux and not allowed to install any extension.
There is native support to do this. Right click console area and choose "Save as".![enter image description here](https://i.stack.imgur.com/uolJ5.png)
