1/25/2024 0 Comments Undo git commit![]() ![]() If we check the log, it'll look much like last time: $ git log -pretty=onelineÄ¥5db4f399d1ad64e0a40e1858d23fef0ffe31fb0 (HEAD -> main) Added file. Instead of removing all the commits in its way, the revert ONLY undoes a single commit by taking you back to the staged files before the commit. This time around, the changes aren't unstaged, like before. Instead of the -soft reset, which we can use to simply undo the commit, while leaving the files intact (and the changes still present, which is why the git status command prompted us with staging the changes) - we can also do a -hard reset: $ git reset -hard HEAD~ Let's go ahead and re-commit this mistake again, so we can take a look at what happens when we run the -hard option. The -soft flag doesn't reset the changes done to the file, just removes the commit that was made. Say that your latest commit has a commit hash of cc3bbf7, which is followed by (HEAD -> main, origin/main), and a commit message such as 'commit README.md file'. However, what are the contents of the file now? $ nano file.txtÄ«y default, the reset command is -soft. With the git log command, you can also check which commit you want to undo. If you want to generate a patch for just the HEAD commit: git show -patch HEAD > 0001-some-modifications.patch. git diff -patch > 0001-some-modifications.patch. add new commit with the undo of the original one. ![]() A new commit with the undo patch will be committed while the original commit will remain in the history as well. You can generate a patch either by one of the following: This will generate a patch from a diff. The reset command will 'undo' any changes made in the given commit. No changes added to commit (use "git add" and/or "git commit -a") You can revert a patch with: git apply -R ." to discard changes in working directory) This will keep the history the same, and it will not change the record of the branchâs history.(use "git add.
