The "pull" command thus performs two operations: it fetches changes from a remote branch, then merges them into the current branch.

If Alice has made her own changes in the meantime, then she may need to manually fix any conflicts. This merges the changes from Bob's "master" branch into Alice's current branch. She does this with: alice$ cd /home/alice/project When he's ready, he tells Alice to pull changes from the repository at /home/bob/myrepo. The clone is on an equal footing with the original project, possessing its own copy of the original project's history.īob then makes some changes and commits them: (edit files) This creates a new directory "myrepo" containing a clone of Alice's repository. Suppose that Alice has started a new project with a Git repository in /home/alice/project, and that Bob, who has a home directory on the same machine, wants to contribute.īob begins with: bob$ git clone /home/alice/project myrepo If you develop on a branch crazy-idea, then regret it, you can always delete the branch with $ git branch -D crazy-ideaīranches are cheap and easy, so this is a good way to try something out. This command ensures that the changes in the experimental branch are already in the current branch. Will show a nice graphical representation of the resulting history.Īt this point you could delete the experimental branch with $ git branch -d experimental Once you've edited the files to resolve the conflicts, $ git commit -a If there are conflicts, markers will be left in the problematic files showing the conflict $ git diff If the changes don't conflict, you're done. To merge the changes made in experimental into master, run $ git merge experimental You can make a different change on the master branch: (edit file)Īt this point the two branches have diverged, with different changes made in each. Now edit a file, commit the change, and switch back to the master branch: (edit file)Ĭheck that the change you made is no longer visible, since it was made on the experimental branch and you're back on the master branch.

The asterisk marks the branch you are currently on type $ git switch experimental The "experimental" branch is the one you just created, and the "master" branch is a default branch that was created for you automatically. You'll get a list of all existing branches: experimental To create a new branch named "experimental", use $ git branch experimental For example, the section called “git-format-patch(1)” turns a commit into email, and it uses the title on the Subject line and the rest of the commit in the body.Ī single Git repository can maintain multiple branches of development. The text up to the first blank line in a commit message is treated as the commit title, and that title is used throughout Git. Which will automatically notice any modified (but not new) files, add them to the index, and commit, all in one step.Ī note on commit messages: Though not required, it's a good idea to begin the commit message with a single short (less than 50 character) line summarizing the change, followed by a blank line and then a more thorough description. This will again prompt you for a message describing the change, and then record a new version of the project.Īlternatively, instead of running git add beforehand, you can use $ git commit -a Finally, commit your changes with: $ git commit If you need to make any further adjustments, do so now, and then add any newly modified content to the index. Your branch is up to date with 'origin/master'.

(Without -cached, git diff will show you any changes that you've made but not yet added to the index.) You can also get a brief summary of the situation with git status: $ git status You can see what is about to be committed using git diff with the -cached option: $ git diff -cached Modify some files, then add their updated contents to the index: $ git add file1 file2 file3
