若发行版包含pgrep工具则可讲命令简化为，经验值Debain 10, Ubuntu 20.04可用
kill -9
pgrep app
需求#
运行脚本调用其他程序有人值守可以用^C终止运行
若需自动化则要借助kill -9 [pid]终止进程，例如我们需要终止名称中含有app的进程
用法#
ps -ef | grep app | grep -v grep | cut -c 9-15 | xargs kill -9
解析#
ps -ef |将列出所有进程详细信息，传入下级管道grep app |从收到的信息中过滤含有app的行，传入下级管道grep -v grep |从收到信息中反向过滤含有grep的行（即grep进程本身），传入下级管道cut -c 9-15 |从收到信息中裁剪第5-15列，传入下级管道xargs kill -9结束进程（对于无法直接用管道的命令可利用xargs中转，传入参数）
