如何从 cocoa 应用程序运行终端命令？

Question

I have problems running a Terminal command from a Cocoa Application. The input for the Terminal is real easy: /Users/.../Csvmidi </Users/.../test.csv> /Users/.../Melody.mid These are three inputs- three actual paths - are just written in a row and seperated by a spac: the first "Csvmidi" runs a Unix Application which converts the test.csv to an actual hearable MIDI file. Through the terminal it works perfectly...

I just don't get it to work via a Cocoa Application.

        let process = Process()
        process.executableURL = URL(fileURLWithPath: "/bin/zsh/")
        process.arguments = [lblCsvmidi.stringValue,"<"+lblURL.stringValue+">",lblMidi.stringValue]
    //I saved the URL of the UNIX program, test.csv and Melody.mid in a lable just to be sure.
    //lblCsvmidi --> URL of Csvmidi UNIX program
    //lblURL --> URL of test.csv
    //lblMidi --> URL of Melody.mid


        print(lblCsvmidi.stringValue,"<" + lblURL.stringValue + ">",lblMidi.stringValue) 
    // this print command was only made to check the arguments in the terminal if they would work --> they do


        process.terminationHandler = { (process) in
            print("\ndidFinish: \(!process.isRunning)")
        }
        do {

          try process.run()
        } catch {}

When I run the code it gives me either the error of an 75: unmatched" , but actually there isn't a quotation mark in the command - or I get "permission denied" errors.

I tried several bin folders like ( I really tried almost every possible): - /bin/zsh - /bin/csh - /bin/ksh -... What am i doing wrong --> I haven't found information in other Questions here and the Process, NSTask and Bundle informations from Apple haven't helped me so far.

Thanks!!

The following runs without error on my system:

import Cocoa 

let process = Process()
process.executableURL = URL(fileURLWithPath: "/bin/zsh/")

var args : [String]!
args = []
args.append("-c")
args.append("open '/Users/xxxx/Desktop/myApp.app/Contents/MacOS/myApp'")
process.arguments = args
process.terminationHandler = { (process) in
  print("\ndidFinish: \(!process.isRunning)")
}
do {
   try process.run()
 } catch {}

let app = NSApplication.shared
app.setActivationPolicy(.regular)
app.activate(ignoringOtherApps:true)
app.run()

The strings after "-c" would depend on what you are trying to accomplish.
