How to check if a program is running with Ruby?

Whaat

I am pretty sure this can be done. I have done some research but have not found what I am looking for yet.

I just need to know if a given program is running.

Something like this:

if ("indigo.exe").is_running?

do something

end

Maybe it has to be done with a system call...but which call?

tbd

here is one quick way

require "win32ole"
procs = WIN32OLE.connect("winmgmts;\\\\.")
all_proc = []
procs.InstancesOf("win32_process").each do |proc|
  all_proc.push proc.name.to_s.downcase
end
p all_proc.include?("indigo.exe")

Thanks, but I get this error message when SketchUp loads:

Error Loading File ProcessTest.rb
No such file to load -- win32ole

It would be great if this would work without the need for another file.

you need win32ole.so for that example.
... but you still need another file to access process identification (win32ole or win32api)
