1. # 直接整段复制到终端饭已经喂了
   
2. cat <<‘EOA’ > /root/oracle-open-ipv6.sh
   
3. #!/bin/bash
   
4. # 获取第二项接口名并赋值给变量 $A
   
5. A=$(ip a | grep -oP ‘^[0-9]+: K[^:]+(?=:)’ | awk ‘NR==2{print $0}’)
   
6. # 输出 dhclient -6 $A
   
7. echo "Running dhclient -6 $A"
   
8. # 执行 dhclient -6 $A
   
9. dhclient -6 $A
   
10. # 结束脚本
    
11. exit 0
