Eu quero um comando simples (AWK, Perl, etc.) para dividir o arquivo em dois arquivos, conforme mostrado abaixo.

test.pem :

Eu quero dividir este arquivo em 2 arquivos.

filename.key deve conter o conteúdo abaixo:

filename.cert deve conter o conteúdo abaixo:

Você também pode usar duas linhas de grep :

grep -Pzo '(?s)-{5}BEGIN (PRIVATE KEY)-{5}.*?-{5}END -{5}' test.pem > filename.key
grep -Pzo '(?s)-{5}BEGIN (CERTIFICATE)-{5}.*?-{5}END -{5}' test.pem > filename.cert

As opções -P habilitam regexes Perl, -z trata caracteres de nova linha como caracteres normais e -o apenas imprime a parte correspondente, não a linha inteira (pois -z faz com que toda a entrada seja tratada como única linha).

No padrão de expressão regular, a opção (?s) faz com que . também corresponda a caracteres de nova linha.
-{5}BEGIN (PRIVATE KEY)-{5} corresponde ao título de bloco -----BEGIN PRIVATE KEY----- .
.*? corresponde ao conteúdo do bloco (a key / certificate data).% -{5}END -{5} corresponde ao final do bloco. O é avaliado para a string entre colchetes acima ( PRIVATE KEY ou CERTIFICATE ).

Usando o AWK:

awk '/^-----BEGIN PRIVATE KEY-----$/, /^-----END PRIVATE KEY-----$/ {print >"filename.key"; next} {print >"filename.cert"}' test.pem

Script AWK expandido:

/^-----BEGIN PRIVATE KEY-----$/, /^-----END PRIVATE KEY-----$/ {
    print >"filename.key";
    next
}
{
    print >"filename.cert"
}

Se a linha atual estiver no intervalo de uma linha -----BEGIN PRIVATE KEY----- e -----END PRIVATE KEY----- , imprime a linha em filename.key e pula para a próxima linha; caso contrário, imprime a linha em filename.cert .

% cat test.pem 
-----BEGIN PRIVATE KEY-----
