Subject: [PATCH v3 2/6] doc: git-checkout: clarify `git checkout <branch>`
Date: Wed, 03 Sep 2025 16:49:58 +0000 [thread overview]
Message-ID: <940cd17e7e15684c0ca8c7b2994835f63e1fd02a.1756918202.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1962.v3.git.1756918202.gitgitgadget@gmail.com>
From: Julia Evans <julia@jvns•ca>
- Reduce use of jargon ("index", "HEAD")
- Clarify that only identical files will be left unchanged, and that
`git checkout` will fail rather than overwrite an unchanged file
- Explain what `git checkout` with no arguments does in a more direct
way

`git checkout [<branch>]`::
- To prepare for working on _<branch>_, switch to it by updating

+ Switch to _<branch>_. This sets the current branch to _<branch>_ and

+ This will not overwrite uncommitted changes to a file: instead it

-You could omit _<branch>_, in which case the command degenerates to
-"check out the current branch", which is a glorified no-op with
-rather expensive side-effects to show only the tracking information,
-if it exists, for the current branch.
+Running `git checkout` without specifying a branch has no effect except
+to print out the tracking information for the current branch.
