| 11 | +'git switch' [<options>] [--no-guess] <branch> |
| 12 | +'git switch' [<options>] --detach [<start-point>] |
| 13 | +'git switch' [<options>] (-c|-C) <new-branch> [<start-point>] |
| 14 | +'git switch' [<options>] --orphan <new-branch> |
| 15 | + |
| 16 | +DESCRIPTION |
| 17 | +----------- |
| 18 | +Switch to a specified branch. The working tree and the index are |
| 19 | +updated to match the branch. All new commits will be added to the tip |
| 20 | +of this branch. |
| 21 | + |
| 22 | +Optionally a new branch could be created with either `-c`, `-C`, |
| 23 | +automatically from a remote branch of same name (see `--guess`), or |
| 24 | +detach the working tree from any branch with `--detach`, along with |
| 25 | +switching. |
| 26 | + |
| 27 | +Switching branches does not require a clean index and working tree |
| 28 | +(i.e. no differences compared to `HEAD`). The operation is aborted |
| 29 | +however if the operation leads to loss of local changes, unless told |
| 30 | +otherwise with `--discard-changes` or `--merge`. |
| 31 | + |
| 32 | +OPTIONS |
| 33 | +------- |
| 34 | +<branch>:: |
| 35 | + Branch to switch to. |
| 36 | + |
| 37 | +<new-branch>:: |
| 38 | + Name for the new branch. |
| 39 | + |
| 40 | +<start-point>:: |
| 41 | + The starting point for the new branch. Specifying a |
| 42 | + `<start-point>` allows you to create a branch based on some |
| 43 | + other point in history than where HEAD currently points. (Or, |
| 44 | + in the case of `--detach`, allows you to inspect and detach |
| 45 | + from some other point.) |
| 46 | ++ |
| 47 | +You can use the `@{-N}` syntax to refer to the N-th last |
| 48 | +branch/commit switched to using "git switch" or "git checkout" |
| 49 | +operation. You may also specify `-` which is synonymous to `@{-1}`. |
| 50 | +This is often used to switch quickly between two branches, or to undo |
| 51 | +a branch switch by mistake. |
| 52 | ++ |
| 53 | +As a special case, you may use `A...B` as a shortcut for the merge |
| 54 | +base of `A` and `B` if there is exactly one merge base. You can leave |
| 55 | +out at most one of `A` and `B`, in which case it defaults to `HEAD`. |
| 56 | + |
| 57 | +-c <new-branch>:: |
| 58 | +--create <new-branch>:: |
| 59 | + Create a new branch named `<new-branch>` starting at |
| 60 | + `<start-point>` before switching to the branch. This is a |
| 61 | + convenient shortcut for: |
| 62 | ++ |
| 63 | +------------ |
| 64 | +$ git branch <new-branch> |
| 65 | +$ git switch <new-branch> |
| 66 | +------------ |
| 67 | + |
| 68 | +-C <new-branch>:: |
| 69 | +--force-create <new-branch>:: |
| 70 | + Similar to `--create` except that if `<new-branch>` already |
| 71 | + exists, it will be reset to `<start-point>`. This is a |
| 72 | + convenient shortcut for: |
| 73 | ++ |
| 74 | +------------ |
| 75 | +$ git branch -f <new-branch> |
| 76 | +$ git switch <new-branch> |
| 77 | +------------ |
| 78 | + |
| 79 | +-d:: |
| 80 | +--detach:: |
| 81 | + Switch to a commit for inspection and discardable |
| 82 | + experiments. See the "DETACHED HEAD" section in |
| 83 | + linkgit:git-checkout[1] for details. |
| 84 | + |
| 85 | +--guess:: |
| 86 | +--no-guess:: |
| 87 | + If `<branch>` is not found but there does exist a tracking |
| 88 | + branch in exactly one remote (call it `<remote>`) with a |
| 89 | + matching name, treat as equivalent to |
| 90 | ++ |
| 91 | +------------ |
| 92 | +$ git switch -c <branch> --track <remote>/<branch> |
| 93 | +------------ |
| 94 | ++ |
| 95 | +If the branch exists in multiple remotes and one of them is named by |
| 96 | +the `checkout.defaultRemote` configuration variable, we'll use that |
| 97 | +one for the purposes of disambiguation, even if the `<branch>` isn't |
| 98 | +unique across all remotes. Set it to e.g. `checkout.defaultRemote=origin` |
| 99 | +to always checkout remote branches from there if `<branch>` is |
| 100 | +ambiguous but exists on the 'origin' remote. See also |
| 101 | +`checkout.defaultRemote` in linkgit:git-config[1]. |
| 102 | ++ |
| 103 | +`--guess` is the default behavior. Use `--no-guess` to disable it. |
| 104 | + |
| 105 | +-f:: |
| 106 | +--force:: |
| 107 | + An alias for `--discard-changes`. |
| 108 | + |
| 109 | +--discard-changes:: |
| 110 | + Proceed even if the index or the working tree differs from |
| 111 | + `HEAD`. Both the index and working tree are restored to match |
| 112 | + the switching target. If `--recurse-submodules` is specified, |
| 113 | + submodule content is also restored to match the switching |
| 114 | + target. This is used to throw away local changes. |
| 115 | + |
| 116 | +-m:: |
| 117 | +--merge:: |
| 118 | + If you have local modifications to one or more files that are |
| 119 | + different between the current branch and the branch to which |
| 120 | + you are switching, the command refuses to switch branches in |
| 121 | + order to preserve your modifications in context. However, |
| 122 | + with this option, a three-way merge between the current |
| 123 | + branch, your working tree contents, and the new branch is |
| 124 | + done, and you will be on the new branch. |
| 125 | ++ |
| 126 | +When a merge conflict happens, the index entries for conflicting |
| 127 | +paths are left unmerged, and you need to resolve the conflicts |
| 128 | +and mark the resolved paths with `git add` (or `git rm` if the merge |
| 129 | +should result in deletion of the path). |
| 130 | + |
| 131 | +--conflict=<style>:: |
| 132 | + The same as `--merge` option above, but changes the way the |
| 133 | + conflicting hunks are presented, overriding the |
| 134 | + `merge.conflictStyle` configuration variable. Possible values are |
| 135 | + "merge" (default) and "diff3" (in addition to what is shown by |
| 136 | + "merge" style, shows the original contents). |
| 137 | + |
| 138 | +-q:: |
| 139 | +--quiet:: |
| 140 | + Quiet, suppress feedback messages. |
| 141 | + |
| 142 | +--progress:: |
| 143 | +--no-progress:: |
| 144 | + Progress status is reported on the standard error stream |
| 145 | + by default when it is attached to a terminal, unless `--quiet` |
| 146 | + is specified. This flag enables progress reporting even if not |
| 147 | + attached to a terminal, regardless of `--quiet`. |
| 148 | + |
| 149 | +-t:: |
| 150 | +--track:: |
| 151 | + When creating a new branch, set up "upstream" configuration. |
| 152 | + `-c` is implied. See `--track` in linkgit:git-branch[1] for |
| 153 | + details. |
| 154 | ++ |
| 155 | +If no `-c` option is given, the name of the new branch will be derived |
| 156 | +from the remote-tracking branch, by looking at the local part of the |
| 157 | +refspec configured for the corresponding remote, and then stripping |
| 158 | +the initial part up to the "*". This would tell us to use `hack` as |
| 159 | +the local branch when branching off of `origin/hack` (or |
| 160 | +`remotes/origin/hack`, or even `refs/remotes/origin/hack`). If the |
| 161 | +given name has no slash, or the above guessing results in an empty |
| 162 | +name, the guessing is aborted. You can explicitly give a name with |
| 163 | +`-c` in such a case. |
| 164 | + |
| 165 | +--no-track:: |
| 166 | + Do not set up "upstream" configuration, even if the |
| 167 | + `branch.autoSetupMerge` configuration variable is true. |
| 168 | + |
| 169 | +--orphan <new-branch>:: |
| 170 | + Create a new 'orphan' branch, named `<new-branch>`. All |
| 171 | + tracked files are removed. |
| 172 | + |
| 173 | +--ignore-other-worktrees:: |
| 174 | + `git switch` refuses when the wanted ref is already |
| 175 | + checked out by another worktree. This option makes it check |
| 176 | + the ref out anyway. In other words, the ref can be held by |
| 177 | + more than one worktree. |
| 178 | + |
| 179 | +--recurse-submodules:: |
| 180 | +--no-recurse-submodules:: |
| 181 | + Using `--recurse-submodules` will update the content of all |
| 182 | + initialized submodules according to the commit recorded in the |
| 183 | + superproject. If nothing (or `--no-recurse-submodules`) is |
| 184 | + used, the work trees of submodules will not be updated. Just |
| 185 | + like linkgit:git-submodule[1], this will detach `HEAD` of the |
| 186 | + submodules. |
| 187 | + |
| 188 | +EXAMPLES |
| 189 | +-------- |
| 190 | + |
| 191 | +The following command switches to the "master" branch: |
| 192 | + |
| 193 | +------------ |
| 194 | +$ git switch master |
| 195 | +------------ |
| 196 | + |
| 197 | +After working in the wrong branch, switching to the correct branch |
| 198 | +would be done using: |
| 199 | + |
| 200 | +------------ |
| 201 | +$ git switch mytopic |
| 202 | +------------ |
| 203 | + |
| 204 | +However, your "wrong" branch and correct "mytopic" branch may differ |
| 205 | +in files that you have modified locally, in which case the above |
| 206 | +switch would fail like this: |
| 207 | + |
| 208 | +------------ |
| 209 | +$ git switch mytopic |
| 210 | +error: You have local changes to 'frotz'; not switching branches. |
| 211 | +------------ |
| 212 | + |
| 213 | +You can give the `-m` flag to the command, which would try a three-way |
| 214 | +merge: |
| 215 | + |
| 216 | +------------ |
| 217 | +$ git switch -m mytopic |
| 218 | +Auto-merging frotz |
| 219 | +------------ |
| 220 | + |
| 221 | +After this three-way merge, the local modifications are _not_ |
| 222 | +registered in your index file, so `git diff` would show you what |
| 223 | +changes you made since the tip of the new branch. |
| 224 | + |
| 225 | +To switch back to the previous branch before we switched to mytopic |
| 226 | +(i.e. "master" branch): |
| 227 | + |
| 228 | +------------ |
| 229 | +$ git switch - |
| 230 | +------------ |
| 231 | + |
| 232 | +You can grow a new branch from any commit. For example, switch to |
| 233 | +"HEAD~3" and create branch "fixup": |
| 234 | + |
| 235 | +------------ |
| 236 | +$ git switch -c fixup HEAD~3 |
| 237 | +Switched to a new branch 'fixup' |
| 238 | +------------ |
| 239 | + |
| 240 | +If you want to start a new branch from a remote branch of the same |
| 241 | +name: |
| 242 | + |
| 243 | +------------ |
| 244 | +$ git switch new-topic |
| 245 | +Branch 'new-topic' set up to track remote branch 'new-topic' from 'origin' |
| 246 | +Switched to a new branch 'new-topic' |
| 247 | +------------ |
| 248 | + |
| 249 | +To check out commit `HEAD~3` for temporary inspection or experiment |
| 250 | +without creating a new branch: |
| 251 | + |
| 252 | +------------ |
| 253 | +$ git switch --detach HEAD~3 |
| 254 | +HEAD is now at 9fc9555312 Merge branch 'cc/shared-index-permbits' |
| 255 | +------------ |
| 256 | + |
| 257 | +If it turns out whatever you have done is worth keeping, you can |
| 258 | +always create a new name for it (without switching away): |
| 259 | + |
| 260 | +------------ |
| 261 | +$ git switch -c good-surprises |
| 262 | +------------ |
