git-switch - Switch branches
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git switch' [<options>] [--no-guess] <branch>
|
|
'git switch' [<options>] --detach [<start-point>]
|
|
'git switch' [<options>] (-c|-C) <new-branch> [<start-point>]
|
|
'git switch' [<options>] --orphan <new-branch>
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Switch to a specified branch. The working tree and the index are
|
|
updated to match the branch. All new commits will be added to the tip
|
|
of this branch.
|
|
|
|
Optionally a new branch could be created with either `-c`, `-C`,
|
|
automatically from a remote branch of same name (see `--guess`), or
|
|
detach the working tree from any branch with `--detach`, along with
|
|
switching.
|
|
|
|
Switching branches does not require a clean index and working tree
|
|
(i.e. no differences compared to `HEAD`). The operation is aborted
|
|
however if the operation leads to loss of local changes, unless told
|
|
otherwise with `--discard-changes` or `--merge`.
|
|
|
|
THIS COMMAND IS EXPERIMENTAL. THE BEHAVIOR MAY CHANGE.
|
|
|
|
OPTIONS
|
|
-------
|
|
<branch>::
|
|
Branch to switch to.
|
|
|
|
<new-branch>::
|
|
Name for the new branch.
|
|
|
|
<start-point>::
|
|
The starting point for the new branch. Specifying a
|
|
`<start-point>` allows you to create a branch based on some
|
|
other point in history than where HEAD currently points. (Or,
|
|
in the case of `--detach`, allows you to inspect and detach
|
|
from some other point.)
|
|
+
|
|
You can use the `@{-N}` syntax to refer to the N-th last
|
|
branch/commit switched to using "git switch" or "git checkout"
|
|
operation. You may also specify `-` which is synonymous to `@{-1}`.
|
|
This is often used to switch quickly between two branches, or to undo
|
|
a branch switch by mistake.
|
|
+
|
|
As a special case, you may use `A...B` as a shortcut for the merge
|
|
base of `A` and `B` if there is exactly one merge base. You can leave
|
|
out at most one of `A` and `B`, in which case it defaults to `HEAD`.
|
|
|
|
-c <new-branch>::
|
|
--create <new-branch>::
|
|
Create a new branch named `<new-branch>` starting at
|
|
`<start-point>` before switching to the branch. This is a
|
|
convenient shortcut for:
|
|
+
|
|
------------
|
|
$ git branch <new-branch>
|
|
$ git switch <new-branch>
|
|
------------
|
|
|
|
-C <new-branch>::
|
|
--force-create <new-branch>::
|
|
Similar to `--create` except that if `<new-branch>` already
|
|
exists, it will be reset to `<start-point>`. This is a
|
|
convenient shortcut for:
|
|
+
|
|
------------
|
|
$ git branch -f <new-branch>
|
|
$ git switch <new-branch>
|
|
------------
|
|
|
|
-d::
|
|
--detach::
|
|
Switch to a commit for inspection and discardable
|
|
experiments. See the "DETACHED HEAD" section in
|
|
linkgit:git-checkout[1] for details.
|
|
|
|
--guess::
|
|
--no-guess::
|
|
If `<branch>` is not found but there does exist a tracking
|
|
branch in exactly one remote (call it `<remote>`) with a
|
|
matching name, treat as equivalent to
|
|
+
|
|
------------
|
|
$ git switch -c <branch> --track <remote>/<branch>
|
|
------------
|
|
+
|
|
If the branch exists in multiple remotes and one of them is named by
|
|
the `checkout.defaultRemote` configuration variable, we'll use that
|
|
one for the purposes of disambiguation, even if the `<branch>` isn't
|
|
unique across all remotes. Set it to e.g. `checkout.defaultRemote=origin`
|
|
to always checkout remote branches from there if `<branch>` is
|
|
ambiguous but exists on the 'origin' remote. See also
|
|
`checkout.defaultRemote` in linkgit:git-config[1].
|
|
+
|
|
`--guess` is the default behavior. Use `--no-guess` to disable it.
|
|
|
|
-f::
|
|
--force::
|
|
An alias for `--discard-changes`.
|
|
|
|
--discard-changes::
|
|
Proceed even if the index or the working tree differs from
|
|
`HEAD`. Both the index and working tree are restored to match
|
|
the switching target. If `--recurse-submodules` is specified,
|
|
submodule content is also restored to match the switching
|
|
target. This is used to throw away local changes.
|
|
|
|
-m::
|
|
--merge::
|
|
If you have local modifications to one or more files that are
|
|
different between the current branch and the branch to which
|
|
you are switching, the command refuses to switch branches in
|
|
order to preserve your modifications in context. However,
|
|
with this option, a three-way merge between the current
|
|
branch, your working tree contents, and the new branch is
|
|
done, and you will be on the new branch.
|
|
+
|
|
When a merge conflict happens, the index entries for conflicting
|
|
paths are left unmerged, and you need to resolve the conflicts
|
|
and mark the resolved paths with `git add` (or `git rm` if the merge
|
|
should result in deletion of the path).
|
|
|
|
--conflict=<style>::
|
|
The same as `--merge` option above, but changes the way the
|
|
conflicting hunks are presented, overriding the
|
|
`merge.conflictStyle` configuration variable. Possible values are
|
|
"merge" (default) and "diff3" (in addition to what is shown by
|
|
"merge" style, shows the original contents).
|
|
|
|
-q::
|
|
--quiet::
|
|
Quiet, suppress feedback messages.
|
|
|
|
--progress::
|
|
--no-progress::
|
|
Progress status is reported on the standard error stream
|
|
by default when it is attached to a terminal, unless `--quiet`
|
|
is specified. This flag enables progress reporting even if not
|
|
attached to a terminal, regardless of `--quiet`.
|
|
|
|
-t::
|
|
--track::
|
|
When creating a new branch, set up "upstream" configuration.
|
|
`-c` is implied. See `--track` in linkgit:git-branch[1] for
|
|
details.
|
|
+
|
|
If no `-c` option is given, the name of the new branch will be derived
|
|
from the remote-tracking branch, by looking at the local part of the
|
|
refspec configured for the corresponding remote, and then stripping
|
|
the initial part up to the "*". This would tell us to use `hack` as
|
|
the local branch when branching off of `origin/hack` (or
|
|
`remotes/origin/hack`, or even `refs/remotes/origin/hack`). If the
|
|
given name has no slash, or the above guessing results in an empty
|
|
name, the guessing is aborted. You can explicitly give a name with
|
|
`-c` in such a case.
|
|
|
|
--no-track::
|
|
Do not set up "upstream" configuration, even if the
|
|
`branch.autoSetupMerge` configuration variable is true.
|
|
|
|
--orphan <new-branch>::
|
|
Create a new 'orphan' branch, named `<new-branch>`. All
|
|
tracked files are removed.
|
|
|
|
--ignore-other-worktrees::
|
|
`git switch` refuses when the wanted ref is already
|
|
checked out by another worktree. This option makes it check
|
|
the ref out anyway. In other words, the ref can be held by
|
|
more than one worktree.
|
|
|
|
--recurse-submodules::
|
|
--no-recurse-submodules::
|
|
Using `--recurse-submodules` will update the content of all
|
|
initialized submodules according to the commit recorded in the
|
|
superproject. If nothing (or `--no-recurse-submodules`) is
|
|
used, the work trees of submodules will not be updated. Just
|
|
like linkgit:git-submodule[1], this will detach `HEAD` of the
|
|
submodules.
|
|
|
|
EXAMPLES
|
|
--------
|
|
|
|
The following command switches to the "master" branch:
|
|
|
|
------------
|
|
$ git switch master
|
|
------------
|
|
|
|
After working in the wrong branch, switching to the correct branch
|
|
would be done using:
|
|
|
|
------------
|
|
$ git switch mytopic
|
|
------------
|
|
|
|
However, your "wrong" branch and correct "mytopic" branch may differ
|
|
in files that you have modified locally, in which case the above
|
|
switch would fail like this:
|
|
|
|
------------
|
|
$ git switch mytopic
|
|
error: You have local changes to 'frotz'; not switching branches.
|
|
------------
|
|
|
|
You can give the `-m` flag to the command, which would try a three-way
|
|
merge:
|
|
|
|
------------
|
|
$ git switch -m mytopic
|
|
Auto-merging frotz
|
|
------------
|
|
|
|
After this three-way merge, the local modifications are _not_
|
|
registered in your index file, so `git diff` would show you what
|
|
changes you made since the tip of the new branch.
|
|
|
|
To switch back to the previous branch before we switched to mytopic
|
|
(i.e. "master" branch):
|
|
|
|
------------
|
|
$ git switch -
|
|
------------
|
|
|
|
You can grow a new branch from any commit. For example, switch to
|
|
"HEAD~3" and create branch "fixup":
|
|
|
|
------------
|
|
$ git switch -c fixup HEAD~3
|
|
Switched to a new branch 'fixup'
|
|
------------
|
|
|
|
If you want to start a new branch from a remote branch of the same
|
|
name:
|
|
|
|
------------
|
|
$ git switch new-topic
|
|
Branch 'new-topic' set up to track remote branch 'new-topic' from 'origin'
|
|
Switched to a new branch 'new-topic'
|
|
------------
|
|
|
|
To check out commit `HEAD~3` for temporary inspection or experiment
|
|
without creating a new branch:
|
|
|
|
------------
|
|
$ git switch --detach HEAD~3
|
|
HEAD is now at 9fc9555312 Merge branch 'cc/shared-index-permbits'
|
|
------------
|
|
|
|
If it turns out whatever you have done is worth keeping, you can
|
|
always create a new name for it (without switching away):
|
|
|
|
------------
|
|
$ git switch -c good-surprises
|
|
------------
|
|
|
