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"
