How to run sudo command/ call python in ruby

Question

I just started programming in Ruby, I would like to know if you can run a command like "Sudo python XXX.py"

I tried to work with RubyPython, but without success because I do not know how and where is the path of the file to be retrieved.

Does anyone have experience with that?

Answer 1

try using system method from kernel module

Answer 2

EDIT: try this

command_output = `sudo python DIRECTORY`
  p command_output

Where DIRECTORY is the full path of the script you want to execute.

There are several methods, each with their own differences.

# define your variable

dir='/tmp'

# execute your shell command

puts `ls #{dir}`
