Re: [Fab-user] env.hosts

[Christian Vest Hansen]

Fabric takes the env.hosts variable is taken into consideration just
prior to executing a task. So, if you move your env.hosts assignment
to another task and execute that before you execute "doit" then it
will work:

def setup():
  env.user = "keyes"
  env.hosts = ['example.com']

def doit():
  run('ls')

What fabric does, among other things, is that it wraps your task in a
loop that sets env.host_string to each of the hosts in turn. Or
something with a similar effect. And then runs the task for each host.
