Prezados(as),
=C9 uma coisa simples mas n=E3o estou entendendo o porqu=EA de n=E3o funcio=
nar.
O comando ...
# top | grep $(/var/run/progama.pid)
16047 user 20 0 693m 369m 32m S 10 9.3 934:58.25 firefox
16047 user 20 0 693m 369m 32m S 16 9.3 934:58.74 firefox
16047 user 20 0 693m 369m 32m S 15 9.3 934:59.20 firefox
16047 user 20 0 693m 369m 32m R 19 9.3 934:59.76 firefox
16047 user 20 0 693m 369m 32m S 31 9.3 935:00.70 firefox
... mostra o resultado acima ... sem problemas.
Por=E9m, o comando ...
# top | grep $(/var/run/progama.pid) >> arquivo.texto
... n=E3o redireciona a saida para o arquivo.
# cat arquivo.texto
... apresenta "arquivo.texto" vazio.
J=E1 tentei usando "namedpipe", alterando as saidas e entradas (padr=E3o, e=
rro) e nada.
Alguma sugest=E3o? Ou realmente n=E3o =E9 poss=EDvel? hehe
Obrigado.
Saulo.
