DESCRIPTION
-----------
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`), or
-from a named commit. In
-this case, the `-f` and `-b` options are meaningless and giving
+the index file, or from a named <tree-ish> (most often a commit). In
+this case, the `-b` options is meaningless and giving
either of them results in an error. <tree-ish> argument can be
used to specify a specific tree-ish (i.e. commit, tag or tree)
to update the index for the given paths before updating the
working tree.
+The index may contain unmerged entries after a failed merge. By
+default, if you try to check out such an entry from the index, the
+checkout operation will fail and nothing will be checked out.
+Using -f will ignore these unmerged entries. The contents from a
+specific side of the merge can be checked out of the index by
+using --ours or --theirs. With -m, changes made to the working tree
+file can be discarded to recreate the original conflicted merge result.
OPTIONS
-------
Quiet, suppress feedback messages.
-f::
- Proceed even if the index or the working tree differs
- from HEAD. This is used to throw away local changes.
+ When switching branches, proceed even if the index or the
+ working tree differs from HEAD. This is used to throw away
+ local changes.
++
+When checking out paths from the index, do not fail upon unmerged
+entries; instead, unmerged entries are ignored.
+
+--ours::
+--theirs::
+ When checking out paths from the index, check out stage #2
+ ('ours') or #3 ('theirs') for unmerged paths.
-b::
Create a new branch named <new_branch> and start it at
given. Set it to `always` if you want this behavior when the
start-point is either a local or remote branch.
+
-If no '-b' option was given, a name will be made up for you, by stripping
-the part up to the first slash of the tracked branch. For example, if you
-called 'git checkout --track origin/next', the branch name will be 'next'.
+If no '-b' option was given, the name of the new branch will be
+derived from the remote branch, by attempting to guess the name
+of the branch on remote system. If "remotes/" or "refs/remotes/"
+are prefixed, it is stripped away, and then the part up to the
+next slash (which would be the nickname of the remote) is removed.
+This would tell us to use "hack" as the local branch when branching
+off of "origin/hack" (or "remotes/origin/hack", or even
+"refs/remotes/origin/hack"). If the given name has no slash, or the above
+guessing results in an empty name, the guessing is aborted. You can
+explicitly give a name with '-b' in such a case.
--no-track::
Ignore the branch.autosetupmerge configuration variable.
based sha1 expressions such as "<branchname>@\{yesterday}".
-m::
- If you have local modifications to one or more files that
+--merge::
+ When switching branches,
+ if you have local modifications to one or more files that
are different between the current branch and the branch to
which you are switching, the command refuses to switch
branches in order to preserve your modifications in context.
paths are left unmerged, and you need to resolve the conflicts
and mark the resolved paths with `git add` (or `git rm` if the merge
should result in deletion of the path).
++
+When checking out paths from the index, this option lets you recreate
+the conflicted merge in the specified paths.
+
+--conflict=<style>::
+ The same as --merge option above, but changes the way the
+ conflicting hunks are presented, overriding the
+ merge.conflictstyle configuration variable. Possible values are
+ "merge" (default) and "diff3" (in addition to what is shown by
+ "merge" style, shows the original contents).
<new_branch>::
Name for the new branch.
