Question

我需要grep error.log文件以获取*ERROR*和Caused by:下一行中相同的错误标记

例如：我有error.log，如下所示

08.02.2016 00:11:21.541 *ERROR* [158.151.84.34 [1454908281309] GET /content/user/home/people-search.html HTTP/1.1] com.day.cq.wcm.tags.IncludeTag Error while executing script content.jsp

我需要输出

08.02.2016 00:11:21.541 *ERROR* [158.151.84.34 [1454908281309] GET /content/user/home/people-search.html HTTP/1.1] com.day.cq.wcm.tags.IncludeTag Error while executing script content.jsp

Caused by: org.apache.sling.api.SlingException: javax.servlet.ServletException: java.lang.Exception: user person search is not available

我将如何得到这个？

Answer 1

egrep '\*ERROR\*|Caused by:' error.log

Answer 2

怎么样：

grep -e "\*ERROR\*" -e "Caused by:" error.log

Answer 3

你有没有＆＃34;引起：＆＃34;没有＆＃34; ERROR＆＃34;线？例如，你能得到一个＆＃34;警告＆＃34; （或类似的）后跟一个＆＃34;引起的＆＃34;？一个＆＃34; ERROR＆＃34;那不是＆＃34;引起的：＆＃34;？线路的其他部分中的文本比您的目标位置（ERROR的第3个字段，引起的行的起点）怎么样？如果发生任何此类情况，请编辑您的问题，以便在样本输入/输出中包含这些情况。

这是您在上述所有问题中需要保护的：

$ cat tst.awk        
/^[0-9]/ {
    if (inErr) {
        print "No cause found"
    }
    if ($3 == "*ERROR*") {
        print
        inErr = 1
    }
}
inErr && /^Caused by:/ {
    print
    inErr = 0
}
END {
    if (inErr) {
        print "No cause found"
    }
}

$ awk -f tst.awk file
