grep comando no script de shell

Question

Eu tenho um arquivo de log e estou tentando escrever um script de shell para encontrar várias strings em um arquivo em várias linhas.

Por exemplo, se eu ver as frases "class=com.comcast.parker.GetCurrentAudioLanguageResponse" e "status:OK" juntas nos registros, devo imprimir getAudioLanguage SUCCESSFUL else getAudioLanguage FAILED . Então meu script de shell é assim:

logfile=$1

if grep "{\"class\":\"com.comcast.parker.GetCurrentAudioLanguageResponse\"" jags.txt | grep "{\"status\":\"OK\"" | wc -l ; then
    echo "getAudioLanguage SUCCESSFUL"
fi
if grep "{\"class\":\"com.comcast.parker.GetCurrentAudioLanguageResponse\"" $logfile | grep -q "GENERAL_ERROR" | wc -l ; then
    echo "getAudioLanguage FAILED"
fi

Nos logs, recebo status como GENERAL_ERROR , portanto, deve imprimir FAILED , mas a saída é exibida como getAudioLanguage SUCCESSFUL ..

Arquivo de log:

Answer 1

O AWK pode ser um pouco mais fácil de usar:

awk '/GetCurrentAudioLanguageResponse/ && /status\"\:\"GENERAL_ERROR/{ print "FAIL" } /GetCurrentAudioLanguageResponse/ && /status\":\"OK/ {print "SUCCESS"}  ' log.txt

Nesse código, combinamos dois padrões e, se os padrões forem correspondentes, executamos o que está entre as chaves. Para GetCurrentAudioLanguageResponse e status":"GENERAL_ERROR , imprimimos "FAIL" e, para os padrões GetCurrentAudioLanguageResponse e status\":\"OK , imprimimos "SUCCESS"

    

Answer 2

você deve verificar o status de retorno do comando grep. Por exemplo, se o meu arquivo contiver -

  a.b.c.d status:FAILED

executando o comando

  [[ $(grep "a.b.c.d" log | grep "FAIL") ]] && echo  "FAILED"

 FAILED

    

Answer 3

Eu ofereço que você use sed para analisar o arquivo de log:

sed -n '
/{"class":"com.comcast.parker.GetCurrentAudioLanguageResponse"/{
    /"GENERAL_ERROR"/{
        c\getAudioLanguage FAILED
        p
        q
    }
    /"status":"OK"/{
        c\getAudioLanguage SUCCESSFUL
        h
    }
}
${
g
/SUCCESSFUL/p
}
' logfile
