建议添加echo将获取到的IP直接追加/etc/hosts选择的功能，很多服务器无法直接编辑文件。

例如：

echo -e "# github hosts\n# 加速 GitHub 访问\n\n140.82.112.26                 alive.github.com\n20.205.243.168                api.github.com\n185.199.109.153               assets-cdn.github.com\n185.199.108.133               avatars.githubusercontent.com\n185.199.108.133               avatars0.githubusercontent.com\n185.199.109.133               avatars1.githubusercontent.com\n185.199.108.133               avatars2.githubusercontent.com\n185.199.108.133               avatars3.githubusercontent.com\n185.199.108.133               avatars4.githubusercontent.com\n185.199.111.133               avatars5.githubusercontent.com\n185.199.109.133               camo.githubusercontent.com\n140.82.113.21                 central.github.com\n185.199.108.133               cloud.githubusercontent.com\n20.205.243.165                codeload.github.com\n140.82.113.22                 collector.github.com\n185.199.109.133               desktop.githubusercontent.com\n185.199.111.133               favicons.githubusercontent.com\n20.205.243.166                gist.github.com\n54.231.203.97                 github-cloud.s3.amazonaws.com\n16.182.40.145                 github-com.s3.amazonaws.com\n52.217.200.17                 github-production-release-asset-2e65be.s3.amazonaws.com\n52.216.245.76                 github-production-repository-file-5c1aeb.s3.amazonaws.com\n52.216.60.201                 github-production-user-asset-6210df.s3.amazonaws.com\n192.0.66.2                    github.blog\n20.205.243.166                github.com\n140.82.114.18                 github.community\n185.199.108.154               github.githubassets.com\n151.101.1.194                 github.global.ssl.fastly.net\n185.199.108.153               github.io\n185.199.111.133               github.map.fastly.net\n185.199.108.153               githubstatus.com\n140.82.112.26                 live.github.com\n185.199.109.133               media.githubusercontent.com\n185.199.109.133               objects.githubusercontent.com\n13.107.42.16                  pipelines.actions.githubusercontent.com\n185.199.110.133               raw.githubusercontent.com\n185.199.108.133               user-images.githubusercontent.com\n13.107.246.73                 vscode.dev\n140.82.113.22                 education.github.com\n185.199.108.133               private-user-images.githubusercontent.com\n\n# 数据更新时间：4/7/2025, 11:08:39" | sudo tee -a /etc/hosts > /dev/null

我已经写了个脚本， 你可以直接添加到文档中，让网友们愉快的使用。
例如：

curl -fsSL https://tinsfox.com/hosts.sh | bash

#!/bin/bash

# 定义变量
HOSTS_URL="https://github-hosts.tinsfox.com/hosts"
BACKUP_FILE="/etc/hosts.bak.$(date +%Y%m%d%H%M%S)"
TMP_FILE=$(mktemp)

# 颜色定义
RED='\033[0;31m'
GREEN='\033[0;32m'
YELLOW='\033[0;33m'
NC='\033[0m'

# 错误处理
