Lesson 10: Basic menus

This final lesson demonstrates the use of a rudimentary menu system which you can present to the user when he enters the adminmenu command.

if(command=="adminmenu") {
   print("========= Admin Menu =========");
   print("1) Add users");
   print("2) Start a backup");
   print("3) Change ownership of a file");
   print("4) Fix line printer queues");
   choice = input("Please choose one: ");

   switch(choice) {
      case "1":
         if(!getstringpasswd("m9xxg7B4.v8Ck", "Type in the adduser
   password: ", 2))
            reject;
         runcommand = "/usr/local/bin/adduser";
         runuser = "root";
         break;
      case "2":
         runcommand = "/usr/local/bin/dobackup";
         runuser = "backup";
         break;
      case "3":
         runcommand = "/usr/bin/chown";
         runuser = "root";
         break;
      case "4":
         runcommand = "/usr/lib/lpadmin";
         runuser = "root";
         break;
      default:
         printf("\"%s\" was not a valid choice. Sorry.\n", choice);
         reject;
   }
   
   if (choice == "3") {
      file_name=input("Please enter the new owner's name then file name: ");
      arguments = split(file_name);
      runargv = insert(arguments, 0, "Spacer");
   }
   print("** Command to be run :", runcommand);
   print("** User to run command as :", runuser);
   accept;
}

This example shows how to gather input from the user, check the value of a literal hard-coded password, and manipulate command line arguments. It is purely illustrative of the scope and scale of what you can achieve from within a policy file, although there is much more that has not been covered in this lesson.

Refer to Lesson 10 Sample: Basic menus to see the sample policy used in this lesson.

Sample policy files

Electronic copies of the policy file samples used in each lesson are located in the /opt/quest/qpm4u/examples directory and they are reproduced for you in this section.
