# adding and committing
git add -A                        # stages All
git add .                         # stages new and modified, without deleted
git add -u                        # stages modified and deleted, without new
git commit --amend                # Add staged changes to previous commit. Do not use if commit has been pushed.
git commit --amend --no-edit      # Do so without having to edit the commit message.

# remotes - pushing, pulling, and tracking
git fetch                         # gets remote objects and refs. Needed if new branches were added on the remote.
git remote -v                     # Lists all remotes (verbose)
git pull origin master            # Pulls commits from the 'origin' remote's master branch and stores them in the local repo
git push -u origin master         # sets ups tracking so that you can 'git push' without extra args
git show :/^Merge                 # show the last commit whose message matches a regex

# branches - creating, checking out, and merging
git branch                        # list branches
git branch -a                     # list branches including remotes
git branch <MYBRANCH>             # Creates a new branch called "MYBRANCH"
git checkout <MYBRANCH>           # Makes MYBRANCH the active branch
git checkout -b <MYBRANCH>        # create and checkout a new branch
git branch -d <MYBRANCH>          # delete a local branch
git branch -m <MYBRANCH>          # rename the current branch
git checkout --track origin/<MYBRANCH>      # create a new local branch with the same name as the remote and set "upstream" configuration
git merge <MYBRANCH>           # merge the commits from the given branch into the current branch

# tagging
git tag                           # list available tags
git tag -l v1.4.2.*               # search for specific tags
git tag -a v1.4 -m 'version 1.4'  # create an annotated tag
git tag -a v1.2 9fceb02           # tag a specific commit (if you forgot)
git show v1.4                     # show the tag data of a specific tag
git tag v1.4                      # create a lightweight tag
git push --tag                    # you have to explicitly push tags to remotes
git log --date-order --graph --tags --simplify-by-decoration --pretty=format:'%ai %h %d' # show tags with creation dates

# diff
git diff --word-diff
git diff --staged                 # show the changes that have been staged
git diff 0c6de32 HEAD             # compare the current commit to a previous commit

# reset
git reset <FILE_OR_DIRECTORY>     # unstage
git checkout -- <FILE>            # throw away local modifications and reset to last committed version of given file
git checkout 0c6de32              # browse a previous commit in detached HEAD state. git checkout master to reattach.
git reset --hard HEAD             # throw away local modifications and reset to latest of current branch
git reset --hard 0c6de32          # throw away local modifications and reset to specific commit
git clean -f                      # remove untracked files
git revert HEAD                   # Make a commit that undoes the last commit. Used to reset a commit that
                                  # has already been pushed to a remote.

git rm FILE                       # Remove a file from the index
git rm -r FOLDER                  # Remove a folder from the index
# *these are useful if you forgot to create a .gitignore before adding files*

# checkout prev (older) revision
git_prev() {
	git checkout HEAD~

# checkout next (newer) commit

# create a new repo from a directory in an old repo, preserving history
git clone <old repo>

git remote rm origin
git filter-branch --subdirectory-filter <new repo> -- --all
cd <new repo>
curl -u '<username>' https://api.github.com/user/repos -d '{"name":"<new repo>"}'
