Question

Currently with WMI’s Win32_Process,
I seem unable to detect if a batch file is currently running

all it lists is CommandLine of cmd.exe, without telling me which batch file that particular cmd.exe is running.
Anybody have any insights there?

code snippet (ruby-wmi)

many_args = 'batch_file.bat'
procs = WMI::Win32_Process.find(:all)
procs.each{|proc|
  if (proc.CommandLine.contain?(many_args)) || proc.Name.include?(many_args) # never succeeds

      ...

   end

  }

Answer 1

require 'win32ole'

many_args = "test.cmd"

wmi = WIN32OLE.connect("winmgmts://")

processes = wmi.ExecQuery("select * from win32_process")

processes.each do |process|
  if process.CommandLine != nil && process.CommandLine.include?(many_args) then
    puts process.inspect
    puts "Name: #{process.Name}"
    puts "CommandLine: #{process.CommandLine}"
    puts "CreationDate: #{process.CreationDate}"
    puts "WorkingSetSize: #{process.WorkingSetSize}"
  end
end

The following is my output while the test.cmd is running:

#<WIN32OLE:0x2b8f360>
Name: cmd.exe
CommandLine: cmd /c ""C:\wmi test\test.cmd" "
CreationDate: 20100108083948.497052-300
WorkingSetSize: 1593344
