• 使用grep&sed快速更换Ubuntu为国内镜像源

    1、、原理分析grep&sed查找指定字符串并替换
    命令行：sed -i "s/SAXON_BLE/OWENS_BLE/g" `grep -rl "SAXON_BLE" ./`

    分析：sed：字符串替换命令

               -i：表示当前替换

               "s/SAXON_BLE/OWENS_BLE/g"：s/old_string/new_string/g

               grep：字符串查找命令，功能很强大

               -r：recursive，递归

               -l：返回文件名

                "SAXON_BLE"：需要查找的字符串

                ./：查找路径，表示当前路径

    2，先将源列表文件sources.list备份

    sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

    3、查看sources.list文件，确认需要将archive.ubuntu.com和security.ubuntu.com替换为国内源

    1. ubuntu@docker:~$ cat /etc/apt/sources.list
    2. ## Note, this file is written by cloud-init on first boot of an instance
    3. ## modifications made here will not survive a re-bundle.
    4. ## if you wish to make changes you can:
    5. ## a.) add 'apt_preserve_sources_list: true' to /etc/cloud/cloud.cfg
    6. ##     or do the same in user-data
    7. ## b.) add sources in /etc/apt/sources.list.d
    8. ## c.) make changes to template file /etc/cloud/templates/sources.list.tmpl

    1. ubuntu@docker:~$ sudo sed -i "s/archive.ubuntu.com/mirrors.163.com/g" `grep -rl "archive.ubuntu.com" /etc/apt/sources.list`
    2.
