Just a quick Scala script to convert a certain logfile into CSV. Instead of instinctively going to bash or python for these things, why not Scala? Just run with 'scala makecsv.scala', starts and finishes quickly. No build step or bytecode or support files, just a script.

Logfile to CSV in Scala

println("date,msisdn,message")
scala.io.Source.fromFile("problem.log").getLines().foreach { line =>
  val m = "^(.{19}).*msisdn='(.{10}).*msg='(.*)', status.*".r.findFirstMatchIn(line).get
  println(s"""${m.group(1)},${m.group(2)},"${m.group(3)}"""")
}
