AIX默认安装ksh，对于习惯了bash的人来说,不能tab自动补全,不能翻上/下,感觉使用起来很不方便,在ksh中不能直接实现这些功能,可以使用另外的方法来完成
一.安装bash程序,使用起来就和bash一样
二.ksh中通过其他方法完成
翻上/下条功能
1、在主目录中 vi .profile
2、添加一行：export EDITOR=vi
3、保存.profile，重新登陆;或者source ~/.profile
现在如果要使用翻上/下条功能,只需要按下esc键,然后使用j/k翻上/下即可;如果要退回到输入功能,直接输入i,然后输入即可.其实所有操作就是和vi中的操作一样.
自动补全功能
使用esc+\

通过netstat+rmsock查找AIX端口对应进程
rmsock除去不包含文件描述符的套接字。它接受 socket、tcpcb、inpcb、ripcb 或 rawcb 地址并将其转换成套接字地址。然后检查每个进程所有打开的文件以查找套接字的匹配。如果没找到匹配，对该套接字执行异常终止操作，而不考虑套接字 linger 选项的存在。套接字保留的端口号释放。如果发现匹配，文件描述符和主进程状态显示给用户。

nmon使用说明
Nmon 工具是 IBM 提供的免费的监控 AIX 系统与 Linux 系统资源的工具。该工具可实时监控系统性能，也可以将服务器的系统资源耗用情况收集起来并输出一个特定的文件,并可利用 excel 分析工具进行数据的统计分析,非常利用 UNIX 或者 Linux 系统的性能数据分析。
1.下载地址
nmon官网
NMON_Analyser官网
本地下载nmon
本地下载nmon_analyser
2.安装nmon
在压缩包中找到相应的版本，上传至服务器，然后授予执行权限

-f spreadsheet output format [note: default -s300 -c288] optional -s <seconds> between refreshing the screen [default 2] -c <number> of refreshes [default millions] -t spreadsheet includes top processes 具体信息nmon -h
例如：nmon -f -t -s 30 -c 120
-s 30:每30秒进行一次数据采集
-c 120:一共采集120次
6.分析数据
打开nmon analyser，设置宏的安全级别是低 ，之后点击 Analyser NMON data 按钮 输入文件 保存成excel格式即可。
