Script criado, inicialmente, para auxiliar na manutenção dos usuários em um servidor NIS, onde qualquer pessoa posia adicionar um usuário. mesmo  não conhecendo o linux, mas eu transformei ele em um script de manutenção de usuários bem simples, com as funcionalidades básicas (adicionar e remover usuários).

Ele é todo feito usando a ferramenta Dialog, que deixa o script com uma carinha mais amigável.
