| As contas de usuário | |
| Um arquivo em particular no diretório de configuração do sistema contém a lista de usuários do sistema: /etc/passwd. Ao contrário do que o nome sugere, ele geralmente não contêm senhas de usuários, pois eles são, na maioria dos casos, armazenados usando o formato de sombras em um arquivo separado /etc/shadow por razões de segurança. Ele, no entanto, vem com alguns bits de informações para cada usuário. Uma linha do arquivo passwd que representa um usuário, a seguinte sintaxe deve ser respeitado: | |
| Name:password:ID:group ID:comment:home directory:login shell | |
| Na prática, o bit senha é substituído por "x" indicando que a senha real é armazenado no arquivo /etc/shadow. | |
| Adicionando uma nova conta de usuário pode ser tão simples quanto adicionar uma linha ao arquivo /etc/passwd. Basta utilizar o useradd. | |
| A sintaxe mais básica para este comando é useradd usuário. Isso cria uma nova conta de usuário com as configurações padrão (que pode ser personalizada), um diretório home para o usuário local |
