脚本

今日写了几个脚本，贴出来

1、批量替换nacos id

#!/bin/bash
# 此脚本用来批量替换yaml文件中的nacos id，默认的路径为当前路径

read -p "Please input the directory(default: pwd):" Dir

if [ -n $Dir ]; then
  Dir=./
fi
echo $Dir

read -p "Please input the nacos id:" Nacos_id
Files=`ls -l ${Dir} | grep -v total | awk '{print $NF}' | grep -E "yml|yaml"`

for file in $Files
do
  sed -i "s/-Dnamespace=[^ ]+/-Dnamespace=$Nacos_id/g" ${Dir}/${file}
done

 2、检测系统分区是否有异常目录或文件，有则发送邮件

#!/usr/bin/env python3
# -*- coding:utf-8 -*-
