篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了自己实现Linux系统任务管理器(附源码)相关的知识,希望对你有一定的参考价值。
一、前言
之前在操作系统课程中,使用Java实现的任务管理器,使用了Swing界面、Runtime、Process相关类。文章总结和程序下载在下面:
Java调用批处理或可执行文件和Runtime、Process类实现Java版进程管理器:http://blog.csdn.net/ljheee/article/details/52067690
Java进程管理器MyProcess.rar----免积分下载:http://download.csdn.net/detail/ljheee/9598423
虽然基本功能实现了,Java跨平台的特性,也使得这个应用在Linux上跑,但是在实现这个版本之后就已经感觉到Java对操作系统信息的提取与封装是有限的,Process包含的进程信息有限,且操作不方便。
因此最近在Linux课程中,决定用Qt界面+Linux方式实现自己的Linux版任务管理器。在程序设计之前,有必要先了解下Linux系统进程信息提取方式,因为这种“Linux方式”不像Java的Process类封装那样,不管底层,只管调用 process.getInputStream();去读取流。
二、Linux下/proc目录简介
Linux内核提供了一种通过 /proc 文件系统,在运行时访问内核内部数据结构、改变内核设置的机制。proc文件系统是一个伪文件系统,它只存在内存当中,而不占用外存空间。它以文件系统的方式为访问系统内核数据的操作提供接口。
系统中当前运行的每一个进程都有对应的一个目录在/proc下,以进程的 PID号为目录名,它们是读取进程信息的接口。而self目录则是读取进程本身的信息接口,是一个link。
直接打开自己安装的Linux系统,进入/proc,可以看到很多数字命名的文件夹;文件夹名的数字,代表当前运行的一个进程的PID,它是读取进程信息的接口。
Linux下/proc下其他重要目录
/proc/cpuinfo --cpu的信息
/proc/devices --已经加载的设备并分类
/proc/modules --所有加载到内核的模块列表
/proc/stat --所有的CPU活动信息,可采点计算cpu的利用率
/proc/version --Linux内核版本和gcc版本
三、Qt实现Linux版任务管理器
用户和应用程序可以通过/proc得到系统的信息,并可以改变内核的某些参数。由于系统的信息是动态改变的,所以用户或应用程序读取proc文件时,proc文件系统是动态从系统内核读出所需信息并提交的。
我们要显示系统信息,只需进行相应的文件操作就行了。
Qt的发展势头相当猛,qt的可移植性相当强,现在应用程序做界面基本都用Qt。Qt是诺基亚开发的一个跨平台的C++图形用户界面应用程序框架。Qt商业版只能试用30天,不过有GPL版的,可以免费使用。有一个非常不错的免费Qt集成开发环境QtCreator IDE。Linux版任务管理器采用的是Qt来实现图形界面。
步骤:
1、Linux下安装Qt Creator,打开新建一个工程,工程目录下,相关文件会有6个,具体见下图--工程文件夹:
编译完成后的实现效果:
“内存信息”模块:
“进程信息”模块:
“模块信息”模块:
“系统信息”模块:
“关于”模块:
