需要有关 shell scipt 的一些帮助(使用 grep 命令) [英] Need some help on shell scipt (using grep command)

问题描述

我有一个日志文件，我正在尝试编写一个 shell 脚本来在文件中的多行中查找多个字符串.

I have a log file and I am trying to write a shell script to find multiple strings in a file on multiple lines.

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

For example if I see the phrases "class=com.comcast.parker.GetCurrentAudioLanguageResponse" and "status:OK" together in the logs, I should print getAudioLanguage SUCCESSFUL else getAudioLanguage FAILED. So my shell script goes like this:

脚本文件:

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，所以它应该打印 FAILED，但输出显示为 getAudioLanguage SUCCESSFUL ..

In the logs, I get status as GENERAL_ERROR, so it should print FAILED, but the output shows as getAudioLanguage SUCCESSFUL ..

对此有什么帮助吗?

推荐答案

您可以使用单个 awk 而不是多个 grep 来做到这一点:

Rather than multiple grep you can use a single awk to do this:

awk '/{"class":"com\.comcast\.parker\.GetCurrentAudioLanguageResponse"/{
   exit ($0 !~ /"status":"GENERAL_ERROR"/)}' file && echo "getAudioLanguage FAILED"

awk '/{"class":"com\.comcast\.parker\.GetCurrentAudioLanguageResponse"/{
   exit ($0 !~ /"status":"OK"/)}' file && echo "getAudioLanguage SUCCESSFUL"
