+## 什么是进程？
+在了解进程的时候，首先得知道什么是程序。
+操作系统其实学过，程序被执行时，操作系统将可执行文件复制到内存中，这就是程序，而进程则是程序的实例，是系统资源分配的基本单位，它被唯一标识于 PCB 之中，也就是进程控制块。
+
+## ps 命令 查看进程
+>Note that ps -aux is distinct from ps aux.  The POSIX and UNIX standards require that ps -aux print all processes owned by a user named x, as well as printing all processes that would be selected by the -a option.  If the user named x does not exist, this ps may
+ interpret the command as ps aux instead and print a warning.  This behavior is intended to aid in transitioning old scripts and habits. It is fragile, subject to change, and thus should not be relied upon.
+
+>To see every process on the system using BSD syntax:
+          ps ax
+          ps axu
+
+也就是说，我们可以通过 **ps axu** 来查看系统中的进程
+
+## top 命令 查看进程
+> The  top program provides a dynamic real-time view of a running system.
+
+这个命令显示的进程状态是动态更新的。
+以下是常用命令：
+- q：退出top命令
+- <Space>：立即刷新
+- s：设置刷新时间间隔
+- t：显示或隐藏进程和CPU状态信息
+- m：显示或隐藏内存状态信息
+- P：按%CPU使用率排行
+- M：按%MEM排行
+- u：指定显示用户进程
+- k：kill进程
+- i：只显示正在运行的进程
+- h：帮助命令。
