Thanks a lot for the help to use some unix command like ps.

I do something easier

exec("ruby a.rb | ps 1>logFile")

and next grep the file for a ruby process.

And now born another problem if

I running directly with ruby like name$ ruby file.rb and in the file I 
have the information but move it into a rails files doesn t work.

Any suggest??

thanks to all have a nice day
