我把自己碰到的问题记录下，备忘。
1 修改文件并提交到github
[luwenwei@dev01v ~/git/helww/labs]$ vim README [luwenwei@dev01v ~/git/helww/labs]$ git diff diff --git a/README b/README index 39d8172..464c83f 100644 --- a/README +++ b/README @@ -3,3 +3,4 @@ This is my github website. Welcome! Here is introduction: 1, labs is my lab, where some joy code is put 2, this maybe isnot project, but who knows +3, and some useful testcase [luwenwei@dev01v ~/git/helww/labs]$ git commit README -m "small change" [master b8bc06a] small change 1 file changed, 1 insertion(+) [luwenwei@dev01v ~/git/helww/labs]$ git push origin master README Enter passphrase for key '/home/luwenwei/.ssh/id_rsa': error: src refspec README does not match any. error: 无法推送一些引用到 'git@github.com:helww/labs' [luwenwei@dev01v ~/git/helww/labs]$ git push origin master Enter passphrase for key '/home/luwenwei/.ssh/id_rsa': Counting objects: 8, done.

解释：
git push origin master README
这句的意思是提交本地的commit到远程仓库，README是要提交的文件，但是此命令执行失败。
正确的命令是：git push origin master（把一次本地commit提交到远程仓库）
2 问题：git push提示origin似乎不是repo
[luwenwei@appdev115 ~/git/helww/labs]$ git pull origin master fatal: 'origin' does not appear to be a git repository fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.

解决步骤：1，git remote add origin；2，git pull origin master
1建立本地和远程的映射；2，拉远程代码到本地
3 查看本地修改列表：git diff --name-status
[luwenwei@dev01v ~/project/smartcloud/iot_biz]$ git diff --name-status M deploy/conf.sh M deploy/deploy.sh M project/autoload_builder.sh M project/build_includes.php M src/domain/knowledges/constants.php M src/proxy/http_proxy.php D tags M tasks/common_task_header.php M test/global.php M test/junit.xml
4 查看本地文件状态：git status（比git diff --name-status好的地方是能把新增的文件也列出来）
[luwenwei@dev01v ~/project/smartcloud/iot_biz]$ git status # 位于分支 master # 尚未暂存以备提交的变更： # （使用 "git add/rm <file>..." 更新要提交的内容） # （使用 "git checkout -- <file>..." 丢弃工作区的改动） # # 修改： deploy/conf.sh # 修改： deploy/deploy.sh # 修改： project/autoload_builder.sh # 修改： project/build_includes.php # 修改： src/domain/knowledges/constants.php # 修改： src/proxy/http_proxy.php # 删除： tags # 修改： tasks/common_task_header.php # 修改： test/global.php # 修改： test/junit.xml # # 未跟踪的文件: # （使用 "git add <file>..." 以包含要提交的内容） # # config/server/server_conf.php.lww # deploy/check.sh # deploy/deploy-beta.sh # src/logic/mnpartner_logic.php # src/service/amap_svc.php # src/service/position_svc.php # tasks/mn_fridge_cosumer.php # tasks/mn_fridge_producer.php # test/biz-process_log # test/env.php # test/test_AmapService.php # test/test_MnPartnerLogic.php # test/test_PostionService.php # tools 修改尚未加入提交（使用 "git add" 和/或 "git commit -a"）
