Pushing changes to master done on a checkout's commit-CodePudding

I did:

From branch master
git checkout 09b17a7eebd4
made changes assuming working on master branch
git add
git commit
git push origin master (nothing happened)

git checkout master
git log shows what did on commit 09b17a7eebd4
git pull origin master (Everything up-to date)

I want those changes to reflect to master. Please help fix this issue.

git reflog

CodePudding user response：

When you checkout a specific commit, you are entering a detached HEAD mode. You are no longer in a breach (the commit could belong to many branches after all). As a result, any commit you make is no longer associated with a branch.

Luckily, no commit is lost. You can find any commit (including previous versions after you have amended a commit) using git reflog. From there, once you found the commit SHA you need, you can cherry-pick in in the branch you need it.
