Question

How can I pass a parameter to a fabric task when calling “fab” from the command line? For example:

def task(something=''):
    print "You said %s" % something

$ fab task "hello"
You said hello

Done.

Is it possible to do this without prompting with fabric.operations.prompt?

Fabric 2 task arguments documentation:

Fabric 1.X uses the following syntax for passing arguments to tasks:

 fab task:'hello world'
 fab task:something='hello'
 fab task:foo=99,bar=True
 fab task:foo,bar

You can read more about it in Fabric docs.
