Sqlite Database Doesn't "Reset" -

-

i have rspec file runs following method before , after each "describe" test block: 

  def self.reset     commands = [       "del #{cats_db_file}", #the "del" changed "rm" windows       "cat #{cats_sql_file} > sqlite3 #{cats_db_file}" # | used before (pipe in linux)     ]      commands.each { |command| `#{command}` }     dbconnection.open(cats_db_file)   end

i'm running of in windows command line. reason, database overpopulates repeatedly; seems database doesn't "clear" itself, when test block run, same attributes added again. syntax in commands array above okay? kind of new this, appreciate suggestions!
