The sync command ("synchronize this branch") updates the current branch and its remote and parent branches with all changes that happened in the repository. When run on the main or a perennial branch, it pulls and pushes updates and tags to the tracking branch. When run on a feature branch, it additionally updates all parent branches and merges the direct parent into the current branch.
If you prefer rebasing your branches instead, set the sync-strategy preference.
If the repository contains a remote called
upstream, it also syncs the main
branch with its upstream counterpart. You can control this behavior with the
--all parameter this command syncs all local branches and not just
the branch you are currently on.
--dry-run parameter allows to test-drive this command. It prints the Git
commands that would be run but doesn't execute them.
