Fabric

For example:

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

$ fab task "hello"
You said hello

Done.

Fabric:

• A library and command line tool for streamlining the use of ssh for application deployment or systems administration tasks to automate deployments, migrations, execute management commands, monitoring no more repetitive maintenance task done manually 

• Fabric 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 need to pass all Python variables as strings, especially if you 
  are using sub-process to run the scripts, or you will get an error. You 
  will need to convert the variables back to int/Boolean types separately.

  def print_this(var):
      print str(var)
  
  fab print_this:'hello world'
  fab print_this='hello'
  fab print_this:'99'
  fab print_this='True'
