Scala Example: a simple cat command

Hi,
Here is a simple Scala script that prints or concatenates text files:

//file: cat.scala
import java.io._



val files = args

for(f <- files){

  val reader = new BufferedReader(new FileReader(f))

  while({ln = reader.readLine; ln != null})

    println(ln)

}

Happy programming!
