Unfortunately docbook does not allow a callout to be referenced from inside a callout list description. Rewrite one paragraph in git-reset man page to work around this limitation. Signed-off-by: Sean Estabrooks <seanlkml@sympatico.ca>

NAME

|
----
|
|
git-checkout - Checkout and switch to a branch
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git-checkout' [-f] [-b <new_branch>] [-m] [<branch>]
|
|
'git-checkout' [-m] [<branch>] <paths>...
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
When <paths> are not given, this command switches branches by
|
|
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.
|
|
|
|
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
|
|
-------
|
|
-f::
|
|
Force a re-read of everything.
|
|
|
|
-b::
|
|
Create a new branch and start it at <branch>.
|
|
|
|
-m::
|
|
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.
|
|
However, with this option, a three-way merge between the current
|
|
branch, your working tree contents, and the new branch
|
|
is done, and you will be on the new branch.
|
|
+
|
|
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`.
|
|
|
|
<new_branch>::
|
|
Name for the new branch.
|
|
|
|
<branch>::
|
|
Branch to checkout; may be any object ID that resolves to a
|
|
commit. Defaults to HEAD.
|
|
|
|
|
|
EXAMPLES
|
|
--------
|
|
|
|
. The following sequence checks out the `master` branch, reverts
|
|
the `Makefile` to two revisions back, deletes hello.c by
|
|
mistake, and gets it back from the index.
|
|
+
|
|
------------
|
|
$ git checkout master <1>
|
|
$ git checkout master~2 Makefile <2>
|
|
$ rm -f hello.c
|
|
$ git checkout hello.c <3>
|
|
------------
|
|
+
|
|
<1> switch branch
|
|
<2> take out a file out of other commit
|
|
<3> restore hello.c from HEAD of current branch
|
|
+
|
|
If you have an unfortunate branch that is named `hello.c`, this
|
|
step would be confused as an instruction to switch to that branch.
|
|
You should instead write:
|
|
+
|
|
------------
|
|
$ git checkout -- hello.c
|
|
------------
|
|
|
|
. After working in a wrong branch, switching to the correct
|
|
branch would be done using:
|
|
+
|
|
------------
|
|
$ git checkout mytopic
|
|
------------
|
|
+
|
|
However, your "wrong" branch and correct "mytopic" branch may
|
|
differ in files that you have locally modified, in which case,
|
|
the above checkout would fail like this:
|
|
+
|
|
------------
|
|
$ git checkout mytopic
|
|
fatal: Entry 'frotz' not uptodate. Cannot merge.
|
|
------------
|
|
+
|
|
You can give the `-m` flag to the command, which would try a
|
|
three-way merge:
|
|
+
|
|
------------
|
|
$ git checkout -m mytopic
|
|
Auto-merging frotz
|
|
------------
|
|
+
|
|
After this three-way merge, the local modifications are _not_
|
|
registered in your index file, so `git diff` would show you what
|
|
changes you made since the tip of the new branch.
|
|
|
|
. When a merge conflict happens during switching branches with
|
|
the `-m` option, you would see something like this:
|
|
+
|
|
------------
|
|
$ git checkout -m mytopic
|
|
Auto-merging frotz
|
|
merge: warning: conflicts during merge
|
|
ERROR: Merge conflict in frotz
|
|
fatal: merge program failed
|
|
------------
|
|
+
|
|
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:
|
|
+
|
|
------------
|
|
$ edit frotz
|
|
$ git update-index frotz
|
|
------------
