匹配多个模式后，使用 awk 或 sed 从文件中分离结果

  • 772

从我们包含一堆 INFO 消息和系统输出行的应用程序日志中，我希望能够提取包含在 2 个模式中的行，然后专门从结果行中的其他行获取值。

这是我的输入文件

              'This is the matching pattern'
tag1: value1
tag2: value2
tag3: value3
'this is the end pattern' xxxyyyzzz

              'This is the matching pattern'
tag1: valuep

2019-08-16 01:38:29,171 1065153992 [http-bio-8443-exec-146] INFO aaaaa
2019-08-16 01:38:29,172 1065153993 [http-bio-8443-exec-146] INFO bbbbb
              'This is the matching pattern1'
tag1: valuexx
tag2: valueyy
tag3: valuezz
'this is the end pattern' xxxyyyzzzadasdqwerty

由此，我想以下列方式提取输出：

输出：

value1, value2
valuea, valueb
valuexx, valueyy

我尝试使用以下方法过滤结果

awk '/This is the matching pattern/,/This is the end pattern/' logfile
OR
awk ' /This is the matching pattern/{flag=1;next}/This is the end pattern/{flag=0}flag' logfile
OR
sed -n -e '/This is the matching pattern/,/this is the end pattern/{ /This is the matching pattern/d; /this is the end pattern/d; p; }'  logfile

但是这些在输出中带来了tag1: valuep，它开始时没有匹配的结束模式。

awk pattern-matching

    从您的示例中，没有理由测试This is the matching pattern，只是结束正则表达式：

    $ cat tst.awk
BEGIN { FS=": "; OFS=", " }
{ f[$1] = $2 }
/this is the end pattern/ {
    print f["tag1"], f["tag2"]
    delete f
}

$ awk -f tst.awk file
value1, value2
valuea, valueb
valuexx, valueyy
