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

You can specify an output stream that catches the text:

import sys.process._
val os   = new java.io.ByteArrayOutputStream
val code = ("volname" #> os).!
os.close()
val opt  = if (code == 0) Some(os.toString("UTF-8")) else None
