shell 脚本上的 grep 命令

shell 脚本上的 grep 命令

我有一个日志文件，我正在尝试编写一个 shell 脚本来查找文件中多行的多个字符串。

例如，如果我在日志中看到短语"class=com.comcast.parker.GetCurrentAudioLanguageResponse"和，我应该打印else 。所以我的 shell 脚本是这样的："status:OK"getAudioLanguage SUCCESSFULgetAudioLanguage FAILED

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

在日志中，我得到的状态为GENERAL_ERROR，因此它应该打印FAILED，但输出显示为getAudioLanguage SUCCESSFUL..

AWK 可能更容易使用一些：

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

在此代码中，我们匹配两个模式，如果模式匹配 - 我们运行大括号中的内容。对于GetCurrentAudioLanguageResponse，status":"GENERAL_ERROR我们打印“失败”，对于模式GetCurrentAudioLanguageResponse，status\":\"OK我们打印“成功”

答案2

您应该检查 grep 命令的返回状态。例如，如果我的文件包含 --

  a.b.c.d status:FAILED

运行命令

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

 FAILED

答案3

我愿意给你提供使用sed解析日志文件：

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