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.
To see the sample policy used in this lesson, see Lesson 10 Sample: Basic menus.
