Git cheat sheet

I have been using Git for more than a year. Comparing with SVN, the big difference is how to commit the changes to remote repository. Git requires two steps to do it:

1. commit the changes to local repository (need to add new files explicitly)
2. push the commit to remote repository

When I first used Git, I often forgot to add new files (git add new_file_name) to let Git track new files, and after commit the changes, I didn't push my changes to remote server.

Here are some commands I would like to share:

Create a new local branch from an existing branch and switch to the new branch:

git checkout -b new_branch existing_branch

Push a newly created branch

git push -u origin new_branch_name

-u will make your branch tracked

Push a tag
         git push origin tag_name

Push all tags not in remote server
        git push origin --tags

Delete a local branch

git branch -D branch_name

Delete a remote branch

git push origin :remote_branch_name

Delete a local tag

git tag -d tag_name

Delete a remote tag

git push origin :refs/tags/tag_name

Remove the references to the deleted remote branches

git remote prune origin

Delete last commit (not pushed yet)

git reset --hard HEAD~1

List all key/value pairs for git config

git config -l

Get a value for a key in git config (for example, get git repository url):

git config --get remote.origin.url

Show all file names changed in a single commit:

git show --pretty="format:" --name-only commit_hash

Cherry Pick

git cherry-pick commit-id-from-other-branch
