Accessing environment variables using $ in Scala process

Question

I'm trying to use a command that uses environment variables, and following is working fine( this is not the actual command I'm going to use).

Seq("echo "+System.getenv("JAVA_HOME"))!

but is there way to use the following kind of syntax ? In the case if we load the command from .sh file ?

Seq("echo ${JAVA_HOME}")!

You can use scala process with bash -c to get environment variables:

import scala.sys.process._
val value = Seq("bash", "-c", "echo $JAVA_HOME").lines.head
