linux shell设置秒级定时任务，宝塔面板可以直接用

#!/bin/bash

step=2 #间隔的秒数，不能大于60

for (( i = 0; i < 60; i=(i+step) )); do

cd /www/wwwroot/目录; php *.php auto #命令行

echo "----------------------------------------------------------------------------"

endDate=`date +"%Y-%m-%d %H:%M:%S"`

echo "★[$endDate] Successful"

echo "----------------------------------------------------------------------------"

sleep $step

done

exit 0
