一起使用echo和grep

我想一起使用echo和grep语句。我已经尝试了大部分但无法得到确切的输出 我想要的。

     aa=$(grep -A100000 "2010-03-24" log.txt|grep "ORA")
     echo "Ip-Address|Directory Name|${aa}" > output.txt

我正在考虑日期，因为我想要在当前日期之后的所有行，然后grep＆＃34; ORA＆＃34;从中。还有其他方法，但根据我的日志文件，这是最合适的方式。 我得到这样的输出。

     10.46.162.86|ASD----Exception|2010-03-24 07 ORA-00001 - 80 -                  
     173.45.230.59 
     2010-03-24 07:00:47 ORA-00942 - 80 - 173.45.230.59
     2010-03-24 07:01:15 ORA-00001 - 80 - 173.45.230.59
     2010-03-24 07:02:17 ORA-12849 - 80 - 173.45.230.59
     2010-03-24 07:05:09 ORA-00001 - 80 - 173.45.230.59

理想的输出应该是

     10.46.162.86|ASD----Exception|2010-03-24 07 ORA-00001 - 80 -  
     173.45.230.59 
     10.46.162.86|ASD----Exception|2010-03-24 07:00:47 ORA-00942 - 80 -    
     173.45.230.59
     10.46.162.86|ASD----Exception|2010-03-24 07:01:15 ORA-00001 - 80 -

     173.45.230.59

我从不同目录的日志文件中获取ORA。

输入就像

这里的问题是当我在进行grep操作时，根据异常提取100行或更多行，并且我能够将Ip-Address和节点名称仅附加到一行。 此外，IP地址和节点名称是在运行时生成的。 请建议一种获得所需输出的方法。 感谢。

答案 0 :(得分：2)

由于我只是知道特殊字符会出现在目录名称中，所以我更喜欢使用awk over sed来避免代码注入问题：

grep -A100000 "2010-03-24" log.txt | awk -v prefix="IP-Address|Directory name|" '/ORA/ { print prefix $0 }' > output.txt

相关部分是

awk -v prefix="IP-Address|Directory name|" '/ORA/ { print prefix $0 }'

使用-v prefix=value，awk知道具有给定值的名为prefix的变量，/ORA/ { print prefix $0 }指示awk处理与正则表达式ORA匹配的所有行打印prefix后跟行（$0）。

@etanreisner给了你答案。

一种方式：

尝试：

grep -A100000 "2010-03-24" log.txt|grep "ORA" |
while read aa
do
   echo "Ip-Address|Directory Name|${aa}"
done > output.txt
