使用 scala.sys.process 修改进程的环境变量? [英] Modifying environment variable for a process with scala.sys.process?

问题描述

我想从 Scala 运行我的进程，并修改了几个环境变量.例如:

I want to run my process from scala, with several environment variables modified. For example:

Seq("bash","echo $asdf") !

和 $asdf 设置为某个值.有没有办法从 Scala 中做到这一点?

and $asdf set to some value. Is there a way to do this from scala?

到目前为止我最接近它:

The closest I got to it so far:

val pb = new java.lang.ProcessBuilder("bash","echo $asdf")
pb.environment.put("asdf","value") }
val p = pb.start()
io.Source.fromInputStream(p.getInputStream).getLines.toList.foreach(println)
p.waitFor()

但这很难看.

推荐答案

Process(Seq("bash", "-c", "echo $asdf"), None, "asdf" -> "Hello, world!").!
