Obtenção de informações sobre o sistema

Colaboração: Rubens Queiroz de Almeida

Data de Publicação: 23 de Julho de 1997

Um programa bastante útil é o programa sysinfo. Este programa gera um relatório contendo informações sobre os dispositivos de hardware existentes no equipamento (disco, memória real e virtual, mouse), data do último boot, e muito mais.

Várias plataformas são suportadas, entre elas, IBM/AIX, Sun/Solaris, SGI/IRIX.

O software encontra-se disponível em ftp://usc.edu/pub/sysinfo/sysinfo-3.3.tar.gz.

Para fornecer uma idéia do tipo de informação gerada, eu estou incluindo abaixo um relatório gerado em uma máquina IBM RS6000, modelo powerpc.
