DESCRIPTION
-----------
updating the index and working tree to reflect the specified
branch, <branch>, and updating HEAD to be <branch> or, if
specified, <new_branch>. Using -b will cause <new_branch> to
-be created.
+be created; in this case you can use the --track or --no-track
+options, which will be passed to `git branch`.
When <paths> are given, this command does *not* switch
branches. It updates the named paths in the working tree from
-the index file (i.e. it runs `git-checkout-index -f -u`). In
-this case, `-f` and `-b` options are meaningless and giving
-either of them results in an error. <branch> argument can be
-used to specify a specific tree-ish to update the index for the
-given paths before updating the working tree.

OPTIONS
-------
+-q::
+ Quiet, suppress feedback messages.
+
-f::
- Force a re-read of everything.
+ Proceed even if the index or the working tree differs
+ from HEAD. This is used to throw away local changes.
-b::
Create a new branch named <new_branch> and start it at
by gitlink:git-check-ref-format[1]. Some of these checks
may restrict the characters allowed in a branch name.
+--track::
+ When -b is given and a branch is created off a remote branch,
+ set up configuration so that git-pull will automatically
+ retrieve data from the remote branch. Use this if you always
+ pull from the same remote branch into the new branch, or if you
+ don't want to use "git pull <repository> <refspec>" explicitly. Set the
+ branch.autosetupmerge configuration variable to true if you
+ want git-checkout and git-branch to always behave as if
+ '--track' were given.
+
+--no-track::
+ When -b is given and a branch is created off a remote branch,
+ set up configuration so that git-pull will not retrieve data
+ from the remote branch, ignoring the branch.autosetupmerge
+ configuration variable.
+
-l::
- Create the new branch's ref log. This activates recording of
- all changes to made the branch ref, enabling use of date
- based sha1 expressions such as "<branchname>@{yesterday}".

-m::
If you have local modifications to one or more files that

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 update-index`.
+and mark the resolved paths with `git add` (or `git rm` if the merge
+should result in deletion of the path).
<new_branch>::
Name for the new branch.
What this means is that you can discard your temporary commits
and merges by switching back to an existing branch (e.g. `git
checkout master`), and a later `git prune` or `git gc` would
-garbage-collect them.
-
-The command would refuse to switch back to make sure that you do
-not discard your temporary state by mistake when your detached
-HEAD is not pointed at by any existing ref. If you did want to
-save your state (e.g. "I was interested in the fifth commit from
-the top of 'master' branch", or "I made two commits to fix minor
-bugs while on a detached HEAD" -- and if you do not want to lose
-these facts), you can create a new branch and switch to it with
-`git checkout -b newbranch` so that you can keep building on
-that state, or tag it first so that you can come back to it
-later and switch to the branch you wanted to switch to with `git
-tag that_state; git checkout master`. On the other hand, if you
-did want to discard the temporary state, you can give `-f`
-option (e.g. `git checkout -f master`) to override this
-behaviour.
+garbage-collect them. If you did this by mistake, you can ask
+the reflog for HEAD where you were, e.g.
+
+------------
+$ git log -g -2 HEAD
+------------
EXAMPLES
At this point, `git diff` shows the changes cleanly merged as in
the previous example, as well as the changes in the conflicted
files. Edit and resolve the conflict and mark it resolved with
-`git update-index` as usual:
+`git add` as usual:
+
------------
$ edit frotz
-$ git update-index frotz
+$ git add frotz
