alive?()

Check status of all processes in the set, returns an array of booleans.

41:                 processes.map { |p| p.alive? }

each() {|p| ...}

47:                 processes.each { |p| yield p }
48:         end
filter(conditions)

Filter by any field that the process responds to. Specify an exact value, or a regular expression. All conditions are put together as a boolean AND, so these two statements are equivalent: 

  processes.filter(:uid => 501).filter(:cmdline => /ruby/)
  processes.filter(:uid => 501, :cmdline => /ruby/)
