If someone else wrote the code you are committing, you can give them credit with the --author option: git commit -m "msg" --author "John Smith <[email protected]>" You can also provide a pattern, which Git will use to search for previous authors: git commit -m &quo...

You can commit changes made to specific files and skip staging them using git add: git commit file1.c file2.h Or you can first stage the files: git add file1.c file2.h and commit them later: git commit

git checkout --orphan new-orphan-branch The first commit made on this new branch will have no parents and it will be the root of a new history totally disconnected from all the other branches and commits. source

You can use git merge --squash to squash changes introduced by a branch into a single commit. No actual commit will be created. git merge --squash <branch> git commit This is more or less equivalent to using git reset, but is more convenient when changes being incorporated have a symbolic...

It is important for someone traversing through the git log to easily understand what each commit was all about. Good commit messages usually include a number of a task or an issue in a tracker and a concise description of what has been done and why, and sometimes also how it has been done. Better m...

Since Git 1.7.12 it is possible to rebase down to the root commit. The root commit is the first commit ever made in a repository, and normally cannot be edited. Use the following command: git rebase -i --root

The editor.apply() method is asynchronous, while editor.commit() is synchronous. Obviously, you should call either apply() or commit(). 2.3 SharedPreferences settings = getSharedPreferences(PREFS_FILE, MODE_PRIVATE); SharedPreferences.Editor editor = settings.edit(); editor.putBoolean(PREF_CONS...

git commit -m 'Fix UI bug' --date 2016-07-01 The --date parameter sets the author date. This date will appear in the standard output of git log, for example. To force the commit date too: GIT_COMMITTER_DATE=2016-07-01 git commit -m 'Fix UI bug' --date 2016-07-01 The date parameter accepts t...

.gitignore ignores files locally, but it is intended to be committed to the repository and shared with other contributors and users. You can set a global .gitignore, but then all your repositories would share those settings. If you want to ignore certain files in a repository locally and not make t...

git blame <file> will show the file with each line annotated with the commit that last modified it.

A commit is probably the object type most familiar to git users, as it's what they are used to creating with the git commit commands. However, the commit does not directly contain any changed files or data. Rather, it contains mostly metadata and pointers to other objects which contain the actual c...

The git commit command does a few things: Create blobs and trees to represent your project directory - stored in .git/objects Creates a new commit object with your author information, commit message, and the root tree from step 1 - also stored in .git/objects Updates the HEAD ref in .git/HEAD t...

Suppose you have many changes in one or more files but from each file you only want to commit some of the changes, you can select the desired changes using: git add -p or git add -p [file] Each of your changes will be displayed individually, and for each change you will be prompted to choose...

This hook is similar to the prepare-commit-msg hook, but it's called after the user enters a commit message rather than before. This is usually used to warn developers if their commit message is in an incorrect format. The only argument passed to this hook is the name of the file that contains the ...

This hook is called immediately after the commit-msg hook. It cannot alter the outcome of the git commit operation, therefore it's used primarily for notification purposes. The script takes no parameters, and its exit status does not affect the commit in any way.

This hook is executed every time you run git commit, to verify what is about to be committed. You can use this hook to inspect the snapshot that is about to be committed. This type of hook is useful for running automated tests to make sure the incoming commit doesn't break existing functionality of...

This hook is called after the pre-commit hook to populate the text editor with a commit message. This is typically used to alter the automatically generated commit messages for squashed or merged commits. One to three arguments are passed to this hook: The name of a temporary file that contains ...

You can use an environment filter to change the author of commits. Just modify and export $GIT_AUTHOR_NAME in the script to change who authored the commit. Create a file filter.sh with contents like so: if [ "$GIT_AUTHOR_NAME" = "Author to Change From" ] then export GIT_A...

A branch is just a pointer to a commit, so you can freely move it around. To make it so that the branch is referring to the commit aabbcc, issue the command git reset --hard aabbcc Please note that this will overwrite your branch's current commit, and as so, its entire history. You might loose s...
