cmd=("./Mcu"  "./C2S" "./AuthServer" "./RegUserServer")
for ((i=0;i<${#cmd[@]};i++))
do
    killall ${cmd[$i]}     
done
echo "Server is kill ........."

for ((i=0;i<${#cmd[@]};i++))
do
    #${cmd[$i]} &
    sleep 1
done
echo "Server is start ........"

    killall ${cmd[$i]}     不执行应该怎么写多谢....

搞不明白,killall 为什么要用循环呢?

还有 ${#cmd[@]} 看不懂什么意思? 能不能给解释解释?

    ${#cmd[@]} 数组元素数啊

ruchong

本意    #${cmd[$i]} &循环执行cmd中的程序
killall     #${cmd[$i]}  循环kiall cmd中的程序

    Array number

有点画蛇添足了，直接for in吧
for c in ${cmd[@]}
do
  killall $c
done
