查看日志的脚本

思路

1, 编写脚本: 在某个文件夹中新建一个文件，如 log

cd /opt/wwwroot/test/shell
vim log

添加内容以下，保存退出

#!/bin/bash

date=`date -d "now" +%Y%m%d` #当天日期
tail -f /opt/log/IfchangeTOB.${date}.log #查看当天日志的命令

2, 添加可执行权限

sudo chmod +x log

3, 将脚本添加至环境变量，这样不管在哪一个文件目录下均可以直接执行log命令

sudo ln -s [log的绝对路径，这里是/opt/wwwroot/test/shell/log] /usr/local/bin/

4, 测试执行

c80k2@c80k2-Vostro-3667❯~$ log

执行顺利

 

思考

一切结构性的操做均可以经过自动化脚原本执行，一次添加，永久使用，安全高效，节省时间．

下一步将生成查看开发环境，测试环境和线上环境的日志脚本.
