The command saves your local modifications away +and reverts the working directory to match the `HEAD` commit. + +The modifications stashed away by this command can be listed with +`git-stash list`, inspected with `git-stash show`, and restored +(potentially on top of a different commit) with `git-stash apply`. +Calling git-stash without any arguments is equivalent to `git-stash +save`. A stash is by default listed as "WIP on 'branchname' ...", but +you can give a more descriptive message on the command line when +you create one. + +The latest stash you created is stored in `$GIT_DIR/refs/stash`; older +stashes are found in the reflog of this reference and can be named using +the usual reflog syntax (e.g. `stash@\{0}` is the most recently +created stash, `stash@\{1}` is the one before it, `stash@\{2.hours.ago}` +is also possible). + +OPTIONS +------- + +save [<message>]:: + + Save your local modifications to a new 'stash', and run `git-reset + --hard` to revert them. This is the default action when no + subcommand is given. The <message> part is optional and gives + the description along with the stashed state. + +list [<options>]:: + + List the stashes that you currently have. Each 'stash' is listed + with its name (e.g. `stash@\{0}` is the latest stash, `stash@\{1}` is + the one before, etc.), the name of the branch that was current when the + stash was made, and a short description of the commit the stash was + based on. ++ +---------------------------------------------------------------- +stash@{0}: WIP on submit: 6ebd0e2...

Add git-stash +---------------------------------------------------------------- ++ +The command takes options applicable to the linkgit:git-log[1] +command to control what is shown and how. + +show [<stash>]:: + + Show the changes recorded in the stash as a diff between the + stashed state and its original parent. When no `<stash>` is given, + shows the latest one. By default, the command shows the diffstat, but + it will accept any format known to `git-diff` (e.g., `git-stash show + -p stash@\{1}` to view the second most recent stash in patch form). + +apply [--index] [<stash>]:: + + Restore the changes recorded in the stash on top of the current + working tree state. When no `<stash>` is given, applies the latest + one. The working directory must match the index. ++ +This operation can fail with conflicts; you need to resolve them +by hand in the working tree. ++ +If the `--index` option is used, then tries to reinstate not only the working +tree's changes, but also the index's ones. However, this can fail, when you +have conflicts (which are stored in the index, where you therefore can no +longer apply the changes as they were originally). + +clear:: + Remove all the stashed states. Note that those states will then + be subject to pruning, and may be difficult or impossible to recover. + +drop [<stash>]:: + + Remove a single stashed state from the stash list. When no `<stash>` + is given, it removes the latest one. i.e. `stash@\{0}` + +pop [<stash>]:: + + Remove a single stashed state from the stash list and apply on top + of the current working tree state. When no `<stash>` is given, + `stash@\{0}` is assumed. See also `apply`. + + +DISCUSSION +---------- + +A stash is represented as a commit whose tree records the state of the +working directory, and its first parent is the commit at `HEAD` when +the stash was created. The tree of the second parent records the +state of the index when the stash is made, and it is made a child of +the `HEAD` commit. The ancestry graph looks like this: + + .----W + / / + -----H----I + +where `H` is the `HEAD` commit, `I` is a commit that records the state +of the index, and `W` is a commit that records the state of the working +tree. + + +EXAMPLES +-------- + +Pulling into a dirty tree:: + +When you are in the middle of something, you learn that there are +upstream changes that are possibly relevant to what you are +doing. When your local changes do not conflict with the changes in +the upstream, a simple `git pull` will let you move forward. ++ +However, there are cases in which your local changes do conflict with +the upstream changes, and `git pull` refuses to overwrite your +changes. In such a case, you can stash your changes away, +perform a pull, and then unstash, like this: ++ +---------------------------------------------------------------- +$ git pull +... +file foobar not up to date, cannot merge. +$ git stash +$ git pull +$ git stash apply +---------------------------------------------------------------- + +Interrupted workflow:: + +When you are in the middle of something, your boss comes in and +demands that you fix something immediately. Traditionally, you would +make a commit to a temporary branch to store your changes away, and +return to your original branch to make the emergency fix, like this: ++ +---------------------------------------------------------------- +... hack hack hack ... +$ git checkout -b my_wip +$ git commit -a -m "WIP" +$ git checkout master +$ edit emergency fix +$ git commit -a -m "Fix in a hurry" +$ git checkout my_wip +$ git reset --soft HEAD^ +... continue hacking ... +---------------------------------------------------------------- ++ +You can use `git-stash` to simplify the above, like this: ++ +---------------------------------------------------------------- +... hack hack hack ... +$ git stash +$ edit emergency fix +$ git commit -a -m "Fix in a hurry" +$ git stash apply +... continue hacking ... +---------------------------------------------------------------- + +SEE ALSO +-------- +linkgit:git-checkout[1], +linkgit:git-commit[1], +linkgit:git-reflog[1], +linkgit:git-reset[1] + +AUTHOR +------ +Written by Nanako Shiraishi <nanako3@bluebottle.com> + +GIT +--- +Part of the linkgit:git[7] suite |
