Linux：Killing Processes in batch。
关于批量删除Linux系统的进程，实现的方式很多。
究其根本，是执行“kill -9”的指令时以不同的方式提供Process ID。
1.获取进程ID。
获取的方式通过“ps -ef | grep xxx”，并结合诸如：awk或者cut等文本截取工具可以获得。
2.批量提供进程ID。
涉及到批量的操作，在编码过程中大多数是通过循环完成的。
在Bash中，有三种循环结构：for、while、until。
在“批量删除进程”的场景中，由于循环边界是有限量的，并且是对全部条目遍历。所以，适合这种情况的循环结构为：for与while。
基于以上分析，以下，列出几个可执行的“批量删除进程”的脚本版本：
版本一、基于：awk
