Python Fabric: filter server output when capturing run () output

Question

Consider a Linux server that has the following line in .bash_profileyour user:

echo "Hello world"

So, every time you enter ssh, you see Hello world

Now consider the following fabric script:

#!/usr/bin/env python
from fabric.api import *

env.hosts = [...]

@task
def test():
    with cd('/'):
        print run('ls').split()

You expect it to output something like:   ['tmp', 'etc', 'var', ...]

But the actual output will be:   ['Hello', 'world', 'tmp', 'etc', 'var', ...]

Is this a bug in the fabric ? Is there any way to suppress server output?

time.sleep() Does not help
