[issue33411] All console message are in the error output in bash interpretor

[Quentin Millardet]

New submission from Quentin Millardet :

The probleme is all display (normal and error message), in bash, are send to 
the screen by the error output. So it's impossible when someone make a bash 
script to get the error back in a log file for exemple, or just to display only 
the error on a screen.

Problem test on Ubuntu 18.04 and Elementary loki (an Ubuntu 16.04 variant)

Quentin Millardet  added the comment:

In a bash terminal, obtained result: 

$python > Normal.txt 2> Error.txt
import a
$cat Normal.txt 
$cat Error.txt 
Python 2.7.12 (default, Dec  4 2017, 14:50:18)

>>> Traceback (most recent call last):

ImportError: No module named a
>>>

That i was expected  :

$python > Normal.txt 2> Error.txt
import a
$cat Normal.txt
