  11'git switch' [<options>] [--no-guess] <branch>
  12'git switch' [<options>] --detach [<start-point>]

  16DESCRIPTION
  17-----------
  18Switch to a specified branch. The working tree and the index are
  19updated to match the branch. All new commits will be added to the tip
  20of this branch.
  21
  22Optionally a new branch could be created with either `-c`, `-C`,
  23automatically from a remote branch of same name (see `--guess`), or
  24detach the working tree from any branch with `--detach`, along with
  25switching.
  26
  27Switching branches does not require a clean index and working tree
  28(i.e. no differences compared to `HEAD`). The operation is aborted
  29however if the operation leads to loss of local changes, unless told
  30otherwise with `--discard-changes` or `--merge`.
  31
  32THIS COMMAND IS EXPERIMENTAL. THE BEHAVIOR MAY CHANGE.
  33
  34OPTIONS
  35-------
  36<branch>::
  37        Branch to switch to.
  38
  39<new-branch>::
  40        Name for the new branch.
  41
  42<start-point>::
  43        The starting point for the new branch. Specifying a
  44        `<start-point>` allows you to create a branch based on some
  45        other point in history than where HEAD currently points. (Or,
  46        in the case of `--detach`, allows you to inspect and detach
  47        from some other point.)
  48+
  49You can use the `@{-N}` syntax to refer to the N-th last
  50branch/commit switched to using "git switch" or "git checkout"
  51operation. You may also specify `-` which is synonymous to `@{-1}`.
  52This is often used to switch quickly between two branches, or to undo
  53a branch switch by mistake.
  54+
  55As a special case, you may use `A...B` as a shortcut for the merge
  56base of `A` and `B` if there is exactly one merge base. You can leave
  57out at most one of `A` and `B`, in which case it defaults to `HEAD`.
  58
  59-c <new-branch>::
  60--create <new-branch>::
  61        Create a new branch named `<new-branch>` starting at
  62        `<start-point>` before switching to the branch. This is a
  63        convenient shortcut for:
  64+
  65------------
  66$ git branch <new-branch>
  67$ git switch <new-branch>
  68------------
  69
  70-C <new-branch>::
  71--force-create <new-branch>::
  72        Similar to `--create` except that if `<new-branch>` already
  73        exists, it will be reset to `<start-point>`. This is a
  74        convenient shortcut for:
  75+
  76------------
  77$ git branch -f <new-branch>
  78$ git switch <new-branch>
  79------------
  80
  81-d::
  82--detach::
  83        Switch to a commit for inspection and discardable
  84        experiments. See the "DETACHED HEAD" section in
  85        linkgit:git-checkout[1] for details.
  86
  87--guess::
  88--no-guess::
  89        If `<branch>` is not found but there does exist a tracking
  90        branch in exactly one remote (call it `<remote>`) with a
  91        matching name, treat as equivalent to
  92+
  93------------
  94$ git switch -c <branch> --track <remote>/<branch>
  95------------
  96+
  97If the branch exists in multiple remotes and one of them is named by
  98the `checkout.defaultRemote` configuration variable, we'll use that
  99one for the purposes of disambiguation, even if the `<branch>` isn't
 100unique across all remotes. Set it to e.g. `checkout.defaultRemote=origin`
 101to always checkout remote branches from there if `<branch>` is
 102ambiguous but exists on the 'origin' remote. See also
 103`checkout.defaultRemote` in linkgit:git-config[1].
 104+
 105`--guess` is the default behavior. Use `--no-guess` to disable it.
 106
 107-f::
 108--force::
 109        An alias for `--discard-changes`.
 110
 111--discard-changes::
 112        Proceed even if the index or the working tree differs from
 113        `HEAD`. Both the index and working tree are restored to match
 114        the switching target. If `--recurse-submodules` is specified,
 115        submodule content is also restored to match the switching
 116        target. This is used to throw away local changes.
 117
 118-m::
 119--merge::
 120        If you have local modifications to one or more files that are
 121        different between the current branch and the branch to which
 122        you are switching, the command refuses to switch branches in
 123        order to preserve your modifications in context.  However,
 124        with this option, a three-way merge between the current
 125        branch, your working tree contents, and the new branch is
 126        done, and you will be on the new branch.
 127+
 128When a merge conflict happens, the index entries for conflicting
 129paths are left unmerged, and you need to resolve the conflicts
 130and mark the resolved paths with `git add` (or `git rm` if the merge
 131should result in deletion of the path).
 132
 133--conflict=<style>::
 134        The same as `--merge` option above, but changes the way the
 135        conflicting hunks are presented, overriding the
 136        `merge.conflictStyle` configuration variable.  Possible values are
 137        "merge" (default) and "diff3" (in addition to what is shown by
 138        "merge" style, shows the original contents).
 139
 140-q::
 141--quiet::
 142        Quiet, suppress feedback messages.
 143
 144--progress::
 145--no-progress::
 146        Progress status is reported on the standard error stream
 147        by default when it is attached to a terminal, unless `--quiet`
 148        is specified. This flag enables progress reporting even if not
 149        attached to a terminal, regardless of `--quiet`.
 150
 151-t::
 152--track::
 153        When creating a new branch, set up "upstream" configuration.
 154        `-c` is implied. See `--track` in linkgit:git-branch[1] for
 155        details.
 156+
 157If no `-c` option is given, the name of the new branch will be derived
 158from the remote-tracking branch, by looking at the local part of the
 159refspec configured for the corresponding remote, and then stripping
 160the initial part up to the "*".  This would tell us to use `hack` as
 161the local branch when branching off of `origin/hack` (or
 162`remotes/origin/hack`, or even `refs/remotes/origin/hack`).  If the
 163given name has no slash, or the above guessing results in an empty
 164name, the guessing is aborted.  You can explicitly give a name with
 165`-c` in such a case.
 166
 167--no-track::
 168        Do not set up "upstream" configuration, even if the
 169        `branch.autoSetupMerge` configuration variable is true.
 170
 171--orphan <new-branch>::
 172        Create a new 'orphan' branch, named `<new-branch>`. All
 173        tracked files are removed.
 174
 175--ignore-other-worktrees::
 176        `git switch` refuses when the wanted ref is already
 177        checked out by another worktree. This option makes it check
 178        the ref out anyway. In other words, the ref can be held by
 179        more than one worktree.
 180
 181--recurse-submodules::
 182--no-recurse-submodules::
 183        Using `--recurse-submodules` will update the content of all
 184        initialized submodules according to the commit recorded in the
 185        superproject. If nothing (or `--no-recurse-submodules`) is
 186        used, the work trees of submodules will not be updated. Just
 187        like linkgit:git-submodule[1], this will detach `HEAD` of the
 188        submodules.
 189
 190EXAMPLES
 191--------
 192
 193The following command switches to the "master" branch:
 194
 195------------
 196$ git switch master
 197------------
 198
 199After working in the wrong branch, switching to the correct branch
 200would be done using:
 201
 202------------
 203$ git switch mytopic
 204------------
 205
 206However, your "wrong" branch and correct "mytopic" branch may differ
 207in files that you have modified locally, in which case the above
 208switch would fail like this:
 209
 210------------
 211$ git switch mytopic
 212error: You have local changes to 'frotz'; not switching branches.
 213------------
 214
 215You can give the `-m` flag to the command, which would try a three-way
 216merge:
 217
 218------------
 219$ git switch -m mytopic
 220Auto-merging frotz
 221------------
 222
 223After this three-way merge, the local modifications are _not_
 224registered in your index file, so `git diff` would show you what
 225changes you made since the tip of the new branch.
 226
 227To switch back to the previous branch before we switched to mytopic
 228(i.e. "master" branch):
 229
 230------------
 231$ git switch -
 232------------
 233
 234You can grow a new branch from any commit. For example, switch to
 235"HEAD~3" and create branch "fixup":
 236
 237------------
 238$ git switch -c fixup HEAD~3
 239Switched to a new branch 'fixup'
 240------------
 241
 242If you want to start a new branch from a remote branch of the same
 243name:
 244
 245------------
 246$ git switch new-topic
 247Branch 'new-topic' set up to track remote branch 'new-topic' from 'origin'
 248Switched to a new branch 'new-topic'
 249------------
 250
 251To check out commit `HEAD~3` for temporary inspection or experiment
 252without creating a new branch:
 253
 254------------
 255$ git switch --detach HEAD~3
 256HEAD is now at 9fc9555312 Merge branch 'cc/shared-index-permbits'
 257------------
 258
 259If it turns out whatever you have done is worth keeping, you can
 260always create a new name for it (without switching away):
 261
 262------------
 263$ git switch -c good-surprises
 264------------
