假设我们的日志nowcoder.txt里，内容如下

12-May-2017 10:02:22.789 信息 [main] org.apache.catalina.startup.VersionLoggerListener.log Server version:Apache Tomcat/8.5.15
12-May-2017 10:02:22.813 信息 [main] org.apache.catalina.startup.VersionLoggerListener.log Server built:May 5 2017 11:03:04 UTC
12-May-2017 10:02:22.813 信息 [main] org.apache.catalina.startup.VersionLoggerListener.log Server number:8.5.15.0
12-May-2017 10:02:22.814 信息 [main] org.apache.catalina.startup.VersionLoggerListener.log OS Name:Windows, OS Version:10
12-May-2017 10:02:22.814 信息 [main] org.apache.catalina.startup.VersionLoggerListener.log Architecture:x86_64

现在需要你提取出对应的值，输出内容如下

serverVersion:Apache Tomcat/8.5.15

serverName:8.5.15.0

osName:Windows

osVersion:10

模因抹杀

grep 正则 -P 使用perl表达式 -o occurence 只截取匹配部分

echo "serverVersion:$(grep -Po "(?<=Server version:).*" nowcoder.txt)"
echo "serverName:$(grep -Po "(?<=Server number:).*" nowcoder.txt)"
echo "osName:$(grep -Po "(?<=OS Name:).*(?=,)" nowcoder.txt)"
echo "osVersion:$(grep -Po "(?<=OS Version:).*" nowcoder.txt)"

取出对应的值，serverName根本就没有，除非在脚本里直接打印，大小写等，总之提出的需求很烂，这题就不解了，下一题

每次遇到题目我都是绞尽脑汁的想着找规律。shell脚本和其他语言不同的或者说shell脚本的精髓就是规律模块操作啊，看到你们一个个遇到题目都写死了，我也没找到规律，很崩溃，shell脚本就不应该出这种题目，这种题目和C语言、C++、Java、python、php等等语言有什么不同吗！
