How to use the command 'git sync' (with examples)

The git sync command is a useful feature available as part of the git-extras suite. It simplifies the process of synchronizing local branches with their remote counterparts, streamlining your workflow in version control. Essentially, git sync helps to keep your local repository in line with the remote one, ensuring that you’re always working with the latest code and helping to avoid potential conflicts when pushing changes.

Sync the current local branch with its remote branch

Code:

git sync

Motivation:

This command is ideal for developers who want to quickly update their current local branch to match the state of the corresponding remote branch. It ensures that any new commits that have been pushed to the remote repository by other contributors or yourself (from a different workstation) are pulled into your local branch. This is crucial for collaborative work, where keeping all collaborators on the same page can significantly reduce the risk of conflicting changes and inconsistencies, thereby improving workflow efficiency and coherence.

Explanation:

• git sync: This succinct command performs a git pull --rebase followed by a git fetch --prune, effectively merging changes from the remote branch into the local branch. git pull --rebase replays your local commits on top of the fetched branch, reducing the chance of conflicts. git fetch --prune helps eliminate references to branches that may have been deleted on the remote, keeping the local repository clean and up-to-date.

Example output:

Updating a1b2c3d..d4e5f6
Fast-forward
 file.txt | 4 ++++
 1 file changed, 4 insertions(+)

Sync the current local branch with the remote main branch

Code:

git sync origin main

Motivation:

This command is particularly beneficial when you’re working on a feature branch or a personal development branch and want to integrate changes from the primary branch (commonly main). It’s a common scenario in modern development practices to regularly integrate changes from the main branch into your feature branch to ensure compatibility and avoid large conflicts during the final merge. Doing this helps maintain a smooth workflow and eases the integration process when your contributions are ready to be merged back into the main branch.

Explanation:

• git sync: Initiates the sync process.
• origin: This argument refers to the remote name. By default in git, origin is the name given to the main remote repository from which the local repository was cloned.
• main: Specifies the branch you want to sync with. main is the default name for the main branch in newer Git repositories, replacing the traditional master. This keeps your local branch in sync with the latest transformations in the main branch.

Example output:

First, rewinding head to replay your work on top of it...
Fast-forwarded branch_name to main.

Sync without cleaning untracked files

Code:

git sync -s remote_name branch_name

Motivation:

There are scenarios where you have untracked files in your local working directory that you don’t want to lose or disturb during a sync operation. These could be configuration files or logs that are useful for personal development but aren’t supposed to be part of the version-controlled project. In such cases, using the git sync -s option will help you keep these untracked files intact while still allowing you to synchronize your branch with the latest updates from the remote.

Explanation:

• git sync: Begins the syncing process.
• -s: This flag modifies the sync operation such that untracked files in the working directory are preserved, avoiding any clean-up that would normally occur in a typical sync.
• remote_name: This specifies the name of the remote repository you are syncing from. By default, this is usually named origin.
• branch_name: The name of the branch from the remote repository with which you wish to sync your local branch.

Example output:

Fetching and rebasing on top of branch_name...
Keeping all untracked files intact.

Conclusion:

The git sync command provides a streamlined way to keep local branches in sync with their remote counterparts. It aids in maintaining current codebases, integrating changes from remote branches, and does so while offering options to preserve important untracked files. By incorporating these commands into your daily workflow, you can improve collaboration efficiency and reduce the likelihood of integration conflicts.
