tail -fgp para um parágrafo

Question

Eu tenho um arquivo de log flutuante que é separado por linhas vazias. É difícil tail com grep 'PID' - quando faço isso, mostra apenas 1 linha.

Esta é a amostra:

[7/12/16 17:00:12:206 WIB] 0000013d ht.integration.js.JavaScriptIntegrationLibraryImplementation I {

Eu só quero ver este parágrafo contendo PID = 00000144

Answer 1

Aparentemente, seu separador de registro ( RS ) é [project worklight_server]

Então tente:

... | awk -v RS=".project worklight_server."  '/00000144/' 

    

Answer 2

Se você sabe o valor de X (número de linhas que você quer) ou se uma aproximação vai fazer, você pode colocar isso depois de seu tail

| grep -A 25 00000144

que lhe dará qualquer linha com 00000144 e as próximas 25 linhas.

Se você não sabe X, mas pode marcar onde a saída deve parar, você pode usar sed , por exemplo. Para ir de uma linha com o PID para uma linha com 'project worklight_server':

| sed -n '/00000144/,/project\ worklight_server/p'
