ios - Swift 3 and Shell command with non regular arguments -


when calling through terminal

(echo authenticate '""'; echo signal newnym; echo quit) | /usr/bin/nc localhost 9051

it works fine. need use via swift. how write put in arguments?

p.s. searching lot of shell syntax , using shell in swift/objc... still can nothing that...

that's shell function:

func shell(_ path: string = "/bin/bash", arguments: [string] = [], waituntilexit: bool = false) -> string {      let task        = process()     task.launchpath = path     task.arguments  = arguments      let pipe = pipe()     task.standardoutput = pipe     task.launch()      let data = pipe.filehandleforreading.readdatatoendoffile()      if waituntilexit {          task.waituntilexit()      }      return string(data: data, encoding: string.encoding.utf8)!  }

calling

self.shell(arguments: ["(echo authenticate '""'; echo signal newnym; echo quit) | /usr/bin/nc localhost 9051"])

output is

no such file or directory (echo authenticate '""'; echo signal newnym; echo quit)

swift thinks ( directory. why?
