These commands are very useful when interacting with a remote repository.
fetch download remote code from a repository's remote URL to your local computer,
merge is used to merge different people's work together with yours, and
pull is a combination of
To grab a complete copy of another user's repository, use
git clone like this:
$ git clone https://nombre de host/USERNAME/REPOSITORY.git # Clones a repository to your computer
You can choose from several different URLs when cloning a repository. While logged in to GitHub, these URLs are available below the repository details:
When you run
git clone, the following actions occur:
- A new folder called
- It is initialized as a Git repository
- A remote named
originis created, pointing to the URL you cloned from
- All of the repository's files and commits are downloaded there
- The default branch is checked out
For every branch
foo in the remote repository, a corresponding remote-tracking branch
refs/remotes/origin/foo is created in your local repository. You can usually abbreviate
such remote-tracking branch names to
git fetch to retrieve new work done by other people. Fetching from a repository grabs all the new remote-tracking branches and tags without merging those changes into your own branches.
If you already have a local repository with a remote URL set up for the desired project, you can grab all the new information by using
git fetch *remotename* in the terminal:
$ git fetch remotename # Fetches updates made to a remote repository
Otherwise, you can always add a new remote and then fetch. For more information, see "Managing remote repositories."
Merging combines your local changes with changes made by others.
Typically, you'd merge a remote-tracking branch (i.e., a branch fetched from a remote repository) with your local branch:
$ git merge remotename/branchname # Merges updates made online with your local work
git pull is a convenient shortcut for completing both
git fetch and
git merge in the same command:
$ git pull remotename branchname # Grabs online updates and merges them with your local work
pull performs a merge on the retrieved changes, you should ensure that
your local work is committed before running the
pull command. If you run into
a merge conflict
you cannot resolve, or if you decide to quit the merge, you can use
git merge --abort
to take the branch back to where it was in before you pulled.
