## 简介 ##

**说明**

本文用示例介绍Linux中查看进程的命令：pstree的用法。

**格式**

PID start at this PID; **default is 1** (init)  
USER show only trees rooted at processes of this user

## **示例** ##

<table> 
 <tbody> 
 <tr> 
 <td style="width:351px;"> 命令 </td> 
 <td style="width:338px;"> 作用 </td> 
 </tr> 
 <tr> 
 <td style="width:351px;">ps -up</td> 
 <td style="width:338px;">打印所有进程（包括进程号和用户名）</td> 
 </tr> 
 <tr> 
 <td style="width:351px;"> pstree -p pid </td> 
 <td style="width:338px;"> 打印pid的进程数 </td> 
 </tr> 
 <tr> 
 <td style="width:351px;"> pstree -p `ps -e | grep java | awk '{print $1}'` | wc -l 或pstree -p pid | wc -l </td> 
 <td style="width:338px;"> 查找java的进程数 </td> 
 </tr> 
 <tr> 
 <td style="width:351px;"> pstree -p | wc -l </td> 
 <td style="width:338px;"> 查询当前整个系统已用的进程数 </td> 
 </tr>
