Simples script para monitorar processos, CPU e memória...
Apenas para brincar e aprender...

A função CPU foi copiada de "by Paul Colby (http://colby.id.au), no rights reserved ;)"

Para executá-lo basta dar permissão:

Ex.:

$ chmod u+x top_of_eli.sh

E executá-lo:

$ ./top_of_eli.sh

Versão 2 - Enviado por eli marques junior em 20/08/2013

Changelog: Uso:

$ ./top_of_eli.sh -t "time for sleep" -c "cpu crit" -p "process crit"

Exemplo:

$ ./top_of_eli.sh -t 60 -c 80 -p 10
