    Thursday, June 7, 2007 10:48 AM
  • I don't think that command would work - the method of giving arguments using / is the windows way. Linux usually takes options using - (hyphen).
    But ps is special in this too - the actual command for listing all processes is
    ps aux
    Yes, no hyphen, no /, nothing. Just ps aux...
