Issuing native system commands in Scala

Question

I want to issue a native system command from a Scala program, and perhaps trap the output. (\"ls\" comes to mind. There may be other ways to get directory information without is

Answer 1

You can do it using sys.process easily:

Executing system commands and getting their status code (exit code):

import sys.process._

val result = "your_command" !
println("result = "+result) // result contain zero for success or non zero for fail

Getting output from system commands:

import sys.process._

val result = "your_command" !!
println("result = "+result) // result contain output from the command

You have several other options (pipeline, Redirect STDOUT, Append to STDOUT and ...), you can see this link.
