#!/bin/bash  
while true;  
do      
    rm  /home/c/temp/*
    sleep 24h
done

but it doesn't work但它不起作用

Answer 1

write a shell script写一个shell脚本

rm /home/c/temp/*

and add a line in the crontab并在 crontab 中添加一行

crontab -e

add the line添加行

0 12 * * * path/to/script

It will execute you script every day at midday.它会在每天中午执行您的脚本。
