How to write the output of Blender console out to a file

Question

Is it possible to launch Blender in a mode where everything that appears in the Blender Console is sent to a file?

That's OK, mods can add the tags that are necessary to your question later. Creating new tags is generally not a good idea, because it makes organization more difficult. — CharlesL, Feb 10 '14 at 18:41

On Linux/Ubuntu its ./blender > myLog123.txt from the working directory.

./blender &> myLog123.txt to include Stderr.

In Python you can do

import sys
file = open(filepath, "w")
sys.stdout = file
#...
#...
sys.stdout = sys.__stdout__ #reset
file.close()

to catch the console output while your script is running.

Changing sys.stdout in Python apparently catches most of the console output, but not everything. – Garrett Feb 10 '14 at 20:23
Oh that's a very cool / useful approach... will definitively try that! – Jeepster Feb 10 '14 at 20:54

On Windows,

Open a command prompt (Windows KeyR, type cmd and hit Enter)
Drag the Blender shortcut or exe onto the prompt
C:\Users\Yourname>C:\Path\to\Blender.exe
Add > %homepath%\Desktop\blender.log
Hit return to start Blender with all console output redirected to blender.log on your Desktop.

For Mac and Linux, have a look here:
