Git Checkout vs Mercurial Update: Switching Branches Across Version Control Systems

The branch was gone. You knew it was there yesterday. Now your hands hover over the keyboard, trying to remember the exact command that will bring it back — but this time, you’re not in Git. You’re in Mercurial.

Switching between Git and Mercurial feels simple until you hit that muscle memory wall. You type git checkout and nothing happens the way you expect. In Mercurial, the equivalent is hg update. The verbs are different, but the concept is the same: you want your working copy to match a specific commit, branch, or tag.

In Git, checkout is a multitool. You use it to move between branches, restore files, or inspect a past commit. In Mercurial, the world is split into smaller commands. hg update changes your files to match a changeset. hg revert restores files. Each is sharper and narrower in focus, and this distinction matters when you work across both systems.

Using Mercurial to check out a branch is straightforward:

hg update branch-name

To jump to a specific commit:

hg update -r changeset-id

To inspect history:

hg log

Every action is explicit. Every switch is deliberate. Mercurial won’t assume you want to do more than you asked.

Git’s checkout command can still feel faster for long-time Git users. But speed at the keyboard comes from habits, and habits come from repetition. Once hg update is wired into your fingers, context-switching between Git and Mercurial stops breaking your flow.

If you need to work with both systems in one project, there are tools and workflows that mirror commands between them. But one truth stays the same: knowing the native commands in both Git and Mercurial makes you faster, calmer, and harder to stop when something breaks.

You can see Git and Mercurial working together — with real branching and history switching — without setting up a single repo yourself. Go to hoop.dev and watch it in action in minutes.
