Scala Process - Capture Standard Out and Exit Code

Question

I\'m working with the Scala scala.sys.process library.

I know that I can capture the exit code with ! and the output with !!

Answer 1

Here's a really simple Scala wrapper that allows you to retrieve stdout, stderr and exit code.

import scala.sys.process._

case class ProcessInfo(stdout: String, stderr: String, exitCode: Int)

object CommandRunner {

def runCommandAndGetOutput(command: String): ProcessInfo = {
    val stdout = new StringBuilder
    val stderr = new StringBuilder
    val status = command ! ProcessLogger(stdout append _, stderr append _)
    ProcessInfo(stdout.toString(), stderr.toString(), status)
  }
}
