Debian如何自动化回收无用进程

在Debian系统中，自动化回收无用进程可以通过编写脚本或使用现有的系统工具来实现。以下是几种常见的方法：

方法一：使用cron定时任务和pkill命令

1. 编写脚本： 创建一个脚本文件，例如cleanup.sh，内容如下：

   #!/bin/bash
   # 终止运行时间超过24小时的进程
   pkill -f "^[^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]* [^ ]*
