Re: Executing a shell command from within a ruby script?


I recently used this to capture stdout and stderr after running
Schtasks.exe on many windows servers SOX audit of scheduled jobs.

I then called it like this
@taskScheduler =,@commandArgs)

P @taskScheduler._stdout

This class executes a Microsoft Windows DOS command

and holds the results of stdin and stdout in

object attributes.

require “win32/open3”

class Win32Command
attr_reader :_stdout, :_stderr
def initialize(command, arguments)
@@command = command
@arguments = arguments
@commandLine = @@command << " " << @arguments
@_stdin, @_stdout, @_stderr = Open3.popen3(@commandLine)
@_stderr.sync = true
