Unable To Start Commandline Process on linux

I have a process started to begin the decompiling process of a jar file. This means I must start an external process on the users computer. On windows, this simply uses a .cmd file and launches it in the command prompt (without shell or a window), but on linux, I cannot get the process to launch. Here is my code:

 public class ProcessHelper {
     public delegate void OutputHandler(string text);
     public static void ForgeInstall(OutputHandler handler){
         handler("Checking Previous Installation...");
         if(Directory.Exists(DirectoryHelper.getMCPDirectoryPath()))Directory.Delete(DirectoryHelper.getMCPDirectoryPath(), true);
 
         handler("Determing OS, Binding Process, and Running Process...");
         if(ProcessHelper.shouldExecuteWindowsCommand()){
             TextFileHelper.replaceStringInFile(DirectoryHelper.getForgeDirectoryPath() + "/install.cmd", "pause", "");
             ProcessHelper.Execute("cd \"" + DirectoryHelper.getForgeDirectoryPath() + "\" && install.cmd");
         }
         else ProcessHelper.Execute("cd '" + DirectoryHelper.getForgeDirectoryPath() + "' && python fml/install.py");
     }
     public static void Execute(string cmd){
         // determing os
         Process p = new Process();
         if(Application.platform == RuntimePlatform.WindowsPlayer || Application.platform == RuntimePlatform.WindowsEditor){
             // windows platform
             p.StartInfo.FileName = "cmd";
             p.StartInfo.Arguments = "/K \"" + cmd + "\"";
             p.StartInfo.CreateNoWindow = true;
             p.StartInfo.UseShellExecute = false;
         }
         else if(Application.platform == RuntimePlatform.LinuxPlayer || Application.platform == RuntimePlatform.OSXPlayer){
             // linux command based os
             p.StartInfo.FileName = "bash";
             p.StartInfo.Arguments = "-c " + cmd + "";
             p.StartInfo.UseShellExecute = false;
         }
         else UnityEngine.Debug.Log("Unknown OS");
         p.Start();
         p.WaitForExit();
     }
     public static bool shouldExecuteWindowsCommand(){
         return (Application.platform == RuntimePlatform.WindowsPlayer || Application.platform == RuntimePlatform.WindowsEditor);
     }
 }
