1. Merge Conflicts<\/h3>\n\n\n\n

Problem<\/strong>: Conflicting changes in the same file on different branches.<\/p>\n\n\n\n

Solution<\/strong>: Manually edit the conflicted files to resolve differences, then add and commit them.<\/p>\n\n\n\n

# Edit the files to resolve conflicts\ngit add [conflicted-file]\ngit commit -m "Resolved merge conflict"<\/pre><\/div>\n\n\n\n
2. Accidentally Committed to the main<\/code> Branch<\/h3>\n\n\n\n
Problem<\/strong>: You made changes and committed them to the main<\/code> branch instead of a feature branch.<\/p>\n\n\n\n
Solution<\/strong>: Create a new branch and move the commits there, then reset the main<\/code> branch.<\/p>\n\n\n\n
git branch feature-branch\ngit reset --hard origin\/main\ngit checkout feature-branch<\/pre><\/div>\n\n\n\n
3. Committing Large Files<\/h3>\n\n\n\n
Problem<\/strong>: You’ve accidentally committed a large file, making the repo hard to clone.<\/p>\n\n\n\n
Solution<\/strong>: Remove the file from history using filter-branch<\/code> or filter-repo<\/code>.<\/p>\n\n\n\n
git filter-branch --tree-filter 'rm -f path\/to\/large-file' HEAD\ngit push origin main --force<\/pre><\/div>\n\n\n\n
4. Detached HEAD State<\/h3>\n\n\n\n
Problem<\/strong>: You’ve ended up in a detached HEAD state.<\/p>\n\n\n\n
Solution<\/strong>: Create a new branch to save your changes and then switch back to a known branch.<\/p>\n\n\n\n
git branch temp-branch\ngit checkout main<\/pre><\/div>\n\n\n\n
5. Undoing the Last Commit<\/h3>\n\n\n\n
Problem<\/strong>: You need to undo the last commit.<\/p>\n\n\n\n
Solution<\/strong>: Use git reset<\/code> or git revert<\/code> depending on whether you want to keep the changes in the working directory.<\/p>\n\n\n\n
# Keep changes in the working directory\ngit reset HEAD~\n\n# Create a new commit that undoes the last one\ngit revert HEAD<\/pre><\/div>\n\n\n\n
6. Forgotten to Add a File to a Commit<\/h3>\n\n\n\n
Problem<\/strong>: You committed but forgot to add a file.<\/p>\n\n\n\n
Solution<\/strong>: Amend the previous commit to include the forgotten file.<\/p>\n\n\n\n
git add forgotten-file.txt\ngit commit --amend --no-edit<\/pre><\/div>\n\n\n\n
7. Cannot Push Changes<\/h3>\n\n\n\n
Problem<\/strong>: You cannot push because someone else pushed changes before you.<\/p>\n\n\n\n
Solution<\/strong>: Pull the latest changes and then push your changes again.<\/p>\n\n\n\n
git pull --rebase\ngit push origin main<\/pre><\/div>\n\n\n\n
8. Lost Commits<\/h3>\n\n\n\n
Problem<\/strong>: You’ve lost commits due to a hard reset or other operation.<\/p>\n\n\n\n
Solution<\/strong>: Use git reflog<\/code> to find the commit hash and then reset to it.<\/p>\n\n\n\n
git reflog\ngit reset 'HEAD@{n}'  # replace n with the position from reflog<\/pre><\/div>\n\n\n\n
9. Ignored Files Keep Showing Up<\/h3>\n\n\n\n
Problem<\/strong>: Files that should be ignored keep appearing in git status<\/code>.<\/p>\n\n\n\n
Solution<\/strong>: Make sure to add the file patterns to .gitignore<\/code> and then remove the tracked files.<\/p>\n\n\n\n
# Add patterns to .gitignore\ngit rm --cached -r .\ngit add .\ngit commit -m "Fixed .gitignore"<\/pre><\/div>\n\n\n\n
10. Mistyped Commit Author<\/h3>\n\n\n\n
Problem<\/strong>: You committed with the wrong user name and email.<\/p>\n\n\n\n
Solution<\/strong>: Use an interactive rebase to amend the author information.<\/p>\n\n\n\n
git rebase -i HEAD~n  # replace n with the number of commits to go back\n# Change 'pick' to 'edit' for commits to amend\ngit commit --amend --author "New Author <email@example.com>"\ngit rebase --continue<\/pre><\/div>\n\n\n\n
11. Accidentally Deleted a Branch<\/h3>\n\n\n\n
Problem<\/strong>: You’ve accidentally deleted a branch that you need to restore.<\/p>\n\n\n\n
Solution<\/strong>: Use git reflog<\/code> to find the commit hash, then create a new branch pointing to it.<\/p>\n\n\n\n
git reflog\ngit checkout -b restored-branch [commit_hash]<\/pre><\/div>\n\n\n\n
12. Cloning Extremely Slow<\/h3>\n\n\n\n
Problem<\/strong>: Git clone is taking too much time for large repositories.<\/p>\n\n\n\n
Solution<\/strong>: Use shallow cloning to fetch only the latest snapshot of the repository.<\/p>\n\n\n\n
git clone --depth 1 [repo_url]<\/pre><\/div>\n\n\n\n
13. Squashing Commits<\/h3>\n\n\n\n
Problem<\/strong>: You want to squash multiple commits into one to clean up your history.<\/p>\n\n\n\n
Solution<\/strong>: Use interactive rebase.<\/p>\n\n\n\n
git rebase -i HEAD~[number_of_commits]\n# Change 'pick' to 'squash' for commits to squash<\/pre><\/div>\n\n\n\n
14. Changing a Remote’s URL<\/h3>\n\n\n\n
Problem<\/strong>: You need to change the URL of a remote repository.<\/p>\n\n\n\n
Solution<\/strong>: Use git remote set-url<\/code>.<\/p>\n\n\n\n
git remote set-url origin [new_url]<\/pre><\/div>\n\n\n\n
15. Tagging a Previous Commit<\/h3>\n\n\n\n
Problem<\/strong>: You forgot to tag a version and want to tag a past commit.<\/p>\n\n\n\n
Solution<\/strong>: Use git tag<\/code>.<\/p>\n\n\n\n
git tag [tag_name] [commit_hash]<\/pre><\/div>\n\n\n\n
16. Unintentional Modifying of Submodule<\/h3>\n\n\n\n
Problem<\/strong>: A submodule was unintentionally updated, and it needs to be reverted.<\/p>\n\n\n\n
Solution<\/strong>: Reset the submodule to the commit stored in the superproject.<\/p>\n\n\n\n
cd [submodule_path]\ngit reset --hard [commit_hash]\ncd ..\ngit add [submodule_path]\ngit commit -m "Revert submodule changes"<\/pre><\/div>\n\n\n\n
17. Discarding Local Changes<\/h3>\n\n\n\n
Problem<\/strong>: You want to discard local changes to a specific file.<\/p>\n\n\n\n
Solution<\/strong>: Use git checkout<\/code>.<\/p>\n\n\n\n
git checkout -- [file_path]<\/pre><\/div>\n\n\n\n
18. Updating a Forked Repository<\/h3>\n\n\n\n
Problem<\/strong>: You have a forked repository and want to update it with changes from the original repo.<\/p>\n\n\n\n
Solution<\/strong>: Add a remote for the original repo, fetch changes, and merge or rebase.<\/p>\n\n\n\n
git remote add upstream [original_repo_url]\ngit fetch upstream\ngit merge upstream\/main<\/pre><\/div>\n\n\n\n
19. Verifying a Tag<\/h3>\n\n\n\n
Problem<\/strong>: You want to verify that a tag is from a trusted source.<\/p>\n\n\n\n
Solution<\/strong>: Use git tag -v [tag_name]<\/code>.<\/p>\n\n\n\n
git tag -v [tag_name]<\/pre><\/div>\n\n\n\n
20. Discarding History<\/h3>\n\n\n\n
Problem<\/strong>: Your repository has too much old and irrelevant history that you’d like to get rid of.<\/p>\n\n\n\n
Solution<\/strong>: Create a shallow clone, and then force push to the original repository. Be cautious, as this will remove history.<\/p>\n\n\n\n
git clone --depth 1 [repo_url] new-folder\ncd new-folder\ngit push origin +main<\/pre><\/div>\n\n\n\n
