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
ubuntu@docker:~$ cat /etc/apt/sources.list
## Note, this file is written by cloud-init on first boot of an instance
## modifications made here will not survive a re-bundle.
## if you wish to make changes you can:
## a.) add 'apt_preserve_sources_list: true' to /etc/cloud/cloud.cfg
## or do the same in user-data
## b.) add sources in /etc/apt/sources.list.d
## c.) make changes to template file /etc/cloud/templates/sources.list.tmpl
# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.
deb http://archive.ubuntu.com/ubuntu impish main restricted

?4、执行替换，并检查替换情况
ubuntu@docker:~$ sudo sed -i "s/archive.ubuntu.com/mirrors.163.com/g" `grep -rl "archive.ubuntu.com" /etc/apt/sources.list`
ubuntu@docker:~$ sudo sed -i "s/security.ubuntu.com/mirrors.163.com/g" `grep -rl "security.ubuntu.com" /etc/apt/sources.list`
ubuntu@docker:~$ cat /etc/apt/sources.list
