我希望能按城市名排序，也就是按每行最后一个正则匹配项排序。已经能用正则表达式匹配所有城市名：

:: (.*?)

现在需要完成最后一步：对这些行按城市名排序，以下是几种实用方法：

方法1：VS Code操作步骤 #

1. 打开列表文件，按Ctrl+H调出替换面板，点击左上角.*按钮启用正则模式
2. 「查找」框输入：^(.*?:: )(.*)$
3. 「替换」框输入：$2|||$1$2（用|||做临时分隔符，把城市名移到行首）
4. 点击「全部替换」，此时每行格式变为城市名|||原行内容
5. 选中所有行，按Ctrl+Shift+P打开命令面板，输入Sort Lines并执行，完成按城市名排序
6. 再次打开替换面板，查找^(.*?)|||，替换为空，点击「全部替换」恢复原格式

方法2：Sublime Text操作步骤 #

1. 打开列表，按Ctrl+H打开替换窗口，勾选「Regular Expression」选项
2. 查找内容：^(.*?:: )(.*)$，替换内容：$2---$1$2
3. 点击「Replace All」后，选中所有行，执行Edit → Sort Lines
4. 再次打开替换窗口，查找^(.*?)---，替换为空，恢复原行格式

方法3：命令行（Linux/macOS） #

如果用终端处理，假设文件名为travel_list.txt，执行以下命令：

sed 's/^\(.*:: \)\(.*\)$/\2|||\1\2/' travel_list.txt | sort | sed 's/^.*|||//' > sorted_travel_list.txt

逻辑说明：

• 第一个sed命令把城市名移到行首并添加分隔符
• sort命令按行首的城市名排序
• 第二个sed命令去掉临时添加的行首内容，结果输出到sorted_travel_list.txt中
