I'm dabbling with the process class and can do basic actions such as ping, ipconfig, etc but am having issues running fan commands. I'm on a Windows machine and have tried it with and without the bin folder in Path. The snippet below is without.

Process cmdLine := Process(["./fan", "-version"])
cmdLine.dir = File(Uri("${Env.cur.homeDir}bin/"))
echo(cmdLine.dir)
cmdLine.run()

cmdLine.join()
cmdLine.kill()

The error I get is "CreateProcess error=193, %1 is not a valid Win32 application".

Hi FMahony,

The reason behind the error message is because fan is actually fan.bat which, in the world of Win32, is NOT a valid executable that can be run via a Process.

Your options are to either start a new Windows Command Interpreter that can interpret the .bat file:

args       := ["cmd", "/C", "fan.bat", "-version"]
cmdLine    := Process(args)
cmdLine.run.join

Or to start a new Java process directly:

homeDir    := Env.cur.homeDir
classpath  := homeDir + `lib/java/sys.jar`
args       := ["java", "-cp", classpath.osPath, "-Dfan.home=${homeDir.osPath}", "fanx.tools.Fan", "-version"]
cmdLine    := Process(args)
cmdLine.run.join

Thanks, SlimerDude! Both options worked like a charm and the explanation was much appreciated.
