def apply(name: String, exitValue: => Int): ProcessBuilder

Creates a scala.sys.process.ProcessBuilder from a String name and a Boolean.

Creates a scala.sys.process.ProcessBuilder from a String name and a Boolean. This can be used to force an exit value, with the name being used for toString.

Source:
Process.scala
def apply(value: Boolean): ProcessBuilder

Creates a scala.sys.process.ProcessBuilder from a Boolean.

def apply(url: URL): URLBuilder

Creates a scala.sys.process.ProcessBuilder from a java.net.URL.

Creates a scala.sys.process.ProcessBuilder from a java.net.URL. This ProcessBuilder can then be used as a Source, so that one can pipe things from it.

Source:
Process.scala
def apply(file: File): FileBuilder

Creates a scala.sys.process.ProcessBuilder from a java.io.File.

Creates a scala.sys.process.ProcessBuilder from a java.io.File. This ProcessBuilder can then be used as a Source or a Sink, so one can pipe things from and to it.

def apply(builder: JProcessBuilder): ProcessBuilder

Creates a scala.sys.process.ProcessBuilder from a java.lang.ProcessBuilder.

Example:

apply((new java.lang.ProcessBuilder("ls", "-l")) directory new java.io.File(System.getProperty("user.home")))
