如何在VSCode中修改文件？Git推送至GitHub遇问题求助

一、VSCode中修改文件的方法 #

• 打开VSCode，通过左侧资源管理器找到目标文件，点击打开
• 在编辑区直接修改内容，未保存时文件名旁会出现*标记
• 按Ctrl+S（Linux环境通用）保存修改，若文件属于Git仓库，已修改的文件旁会出现大写M标识

二、Git推送问题分析与解决 #

从你补充的命令行日志来看，最后一次git push origin master已经成功将代码推送到GitHub。之前的推送失败是因为本地仓库尚未关联远程GitHub仓库，添加origin远程地址后推送流程正常完成。

针对你提到的“主文件因未修改，文件名后无大写M标识”：

• Git的大写M仅标记已追踪且有内容变更的文件，主文件未修改时无标识是正常状态
• 如果主文件从未被Git追踪，需先执行git add 主文件名将其加入暂存区，再执行git commit -m "提交备注"，之后才能随其他文件一起推送
