如何实现 start 、stop、status?

1)启动的时候将进程号写入文件，停止的时候读取文件得到进程号；

pstree pid -p | awk -F"[()]" '{for(i=0;i<=NF;i++)if($i~/[0-9]+/)print $i}' |grep -E -v "\{|\(|\["|xargs kill -9 

#!/bin/shBASE_HOME=/home/apple/testPID=${BASE_HOME}/.pidstatus(){   echo "==========status======="   status=`ps -p $$`   }start() {    echo "==========start==========="}stop() {    echo "===========stop============"    pid=$$    kill_cmd="pstree -p $pid | awk -F \"[()]\" '{for(i=0;i<=NF;i++)if(\$i~/[0-9]+/)print \$i}' |"'grep -v -E "\[|\(|\)|\]"|xargs kill -9'    eval ${kill_cmd}}restart() {    stop;    echo "sleeping.........";    sleep 3;    start;}case "$1" in    'start')        start        ;;    'stop')        stop        ;;    'status')        status        ;;    'restart')        restart        ;;    *)    echo "usage: $0 {start|stop|restart|status}"    exit 1        ;;    esac
