Pessoal Bom Dia,
Preciso monitorar o espaço em disco de um servidor uma vez por dia,
depois vou usar um agente SNMP pra isso, mas no momento pensei em fazer um
shell para me mandar essa informação por e-mail.
Só que as informações vem truncadas, como no exemplo abaixo... Como
fazer para ele "quebrar" as linhas?
PS. O Script de envio de e-mail peguei pronto do site do Eliphas Levy
Theodoro, e acrescentei as variáveis que preciso, mantendo os devidos créditos.
