脚本stop.sh

shell
#!/bin/bash
PID=$(ps -ef | grep python | grep -v grep | awk '{ print $2 }')
if [ -z "${PID}" ]
then
        echo Application is already stopped
else
        echo kill ${PID}
        kill -9 ${PID}
fi

简略

shell
kill -9 $(ps -ef | grep python | grep -v grep | awk '{ print $2 }')

或者：

shell
kill -9 $(ps -ef | grep python | grep -v grep | sed -n '2 p')
