scala.sys.process.ProcessLogger
See theProcessLogger companion object
trait ProcessLogger
Encapsulates the output and error streams of a running process. This is used by scala.sys.process.ProcessBuilder when starting a process, as an alternative to scala.sys.process.ProcessIO, which can be more difficult to use. Note that a ProcessLogger
will be used to create a ProcessIO
anyway. The object BasicIO
has some functions to do that.
Here is an example that counts the number of lines in the normal and error output of a process:
import scala.sys.process._
var normalLines = 0
var errorLines = 0
val countLogger = ProcessLogger(line => normalLines += 1,
line => errorLines += 1)
"find /etc" ! countLogger
