Linux下crontab定时脚本配置

crontab中如何实现每隔多少天执行一次脚本

脚本sh文件

#!/bin/bash
#crontab -e: `00 01 * * 5 . /etc/profile;/bin/sh /usr/local/nginx/logs/clean.sh >> /usr/local/nginx/logs/cleanLogFile.log 2>&1`

time=`date "+%Y-%m-%d %H:%M:%S"`
echo 开始执行clean.sh脚本时间: $time

#清空日志文件
> /usr/local/nginx/logs/xxxFile.log

time=`date "+%Y-%m-%d %H:%M:%S"`
echo 结束执行clean.sh脚本时间: $time
echo -e "\n"

定时crontab配置

每周五凌晨1点执行定时任务

00 01 * * 5 . /etc/profile;/bin/sh /usr/local/nginx/logs/clean.sh >> /usr/local/nginx/logs/cleanLogFile.log 2>&1
