Command and Rule Over Your Shell


Sultan


What is Sultan?

Sultan is a Python package for interfacing with command-line utilities, like yum, apt-get, or ls, in a Pythonic manner. It lets you run command-line utilities using simple function calls.

The simplest way to use Sultan is to just call it:

from sultan.api import Sultan
s = Sultan()
s.sudo("yum install -y tree").run()

Runs:

sudo yum install -y tree;

The recommended way of using Sultan is to use it in Context Management mode. Here is how to use Sultan with Context Management:

from sultan.api import Sultan

with Sultan.load(sudo=True) as s:
  s.yum("install -y tree").run()

Runs:

sudo su - root -c 'yum install -y tree;'

What if we want to install this command on a remote machine? You can easily achieve this using context management:

from sultan.api import Sultan

with Sultan.load(sudo=True, hostname="myserver.com") as sultan:
  sultan.yum("install -y tree").run()

Runs:

ssh root@myserver.com 'sudo su - root -c 'yum install -y tree;''

If you enter a wrong command, Sultan will print out details you need to debug and find the problem quickly.

Here, the same command was run on a Mac:

from sultan.api import Sultan

with Sultan.load(sudo=True, hostname="myserver.com") as sultan:
  sultan.yum("install -y tree").run()

Yields:

[sultan]: sudo su - root -c 'yum install -y tree;'
