You can use find/select with a regular expression:


irb(main):037:0> a = %w{test test2 nothing something}
=> ["test", "test2", "nothing", "something"]
irb(main):038:0> a.find {|x| /test/ =~ x}
=> "test"
irb(main):039:0> a.select {|x| /test/ =~ x}
=> ["test", "test2"]
irb(main):040:0> a.select {|x| /thing/ =~ x}
=> ["nothing", "something"]

Jesus.
