I borrowed a few paragraphs from Johannes's version, and added a few examples.

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` +commands. The default operation when called without options is to +save the changes away. + +The latest stash you created is stored in `$GIT_DIR/refs/stash`; older +stashes are found in the reflog of this refererence and can be named using +the usual reflog syntax (e.g. `stash@{1}` is the stash one previously made, +`stash@{2}` is the one before it, `stash@{2.hours.ago}` is also possible). + +OPTIONS +------- + +(no subcommand):: + + Save your local modifications to a new 'stash', and run `git-reset + --hard` to revert them. + +list:: + + 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), 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}: submit: 6ebd0e2... Add git-stash +stash@{1}: master: 9cc0589... Merge branch 'master' of gfi +---------------------------------------------------------------- + +show []:: + + Show the changes recorded in the stash. When no `` is given, + shows the latest one. By default, the command shows diffstat, but + you can add `-p` option (i.e. `git stash show -p stash@{2}`) to view + it in patch form. + +apply []:: + + Restores the changes recorded in the stash on top of the current + working tree state. When no `` is given, applies the latest + one. The working directory must match the index. When the changes + conflict, you need to resolve them by hand and mark the result with + `git add` as usual. When the changes are cleanly merged, your + earlier local changes stored in the stash becomes the differences + between the index and the working tree (i.e. `git diff`), except + that newly created files are registered in the index (i.e. `git diff + --cached` is necessary to review the newly added files). + +clear:: + Removes all the stashed states. + + +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 +changes that possibly are relevant to what you are doing in the +upstream. 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 first 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 you to fix something immediately. Traditionally, you would +make a commit to a temporary branch to store your changes away, and +come back 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 +-------- +gitlink:git-checkout[1], +gitlink:git-commit[1], +gitlink:git-reflog[1], +gitlink:git-reset[1] + +AUTHOR +------ +Written by Nanako Shiraishi + +GIT +--- +Part of the gitlink:git[7] suite -- 2.30.2
