上次说了一下linux文件操作的命令嵌套linux命令，这次来补充一点内容。
1、！号的使用。例如:
cat /home/i/桌面/apache-tomcat-9/logs/localhost_access_log.2017-08-22.txt | grep [!3]
0:0:0:0:0:0:0:1 - - [22/Aug/2017:16:55:25 +0800] "GET /tomcat.css HTTP/1.1" 304 -
192.168.10.22 - - [10/oct/2005:16:53:06 +0800] 'get/icons/blank.gif http/1.1' 304 -。-k 4: 按第4个字段排序，也就是[03/apr/2002:10:30:17 +0800]具体日志格式111.222.111.222 - - [03/apr/2002:10:30:17 +0800] "get /index.html http/1.1" 200 419。注意tomcat默认使用8080端口，安装了oracle则会占用tomcat的8080linux命令，因此，可以修改tomcat端口---tomcat--e:\tomcat6.0\conf\server.xml---

2、*号的使用。例如：
[root@localhost bin]# ls -all | find *j*
bootstrap.jar
commons-daemon.jar
tomcat-juli.jar
