-git-rebase - Rebase local commits to new upstream head
+git-rebase - Rebase local commits to a new head
SYNOPSIS
--------
'git-rebase' [--onto <newbase>] <upstream> [<branch>]
+'git-rebase' --continue
+
+'git-rebase' --abort
+
DESCRIPTION
-----------
-git-rebase applies to <upstream> (or optionally to <newbase>) commits
-from <branch> that do not appear in <upstream>. When <branch> is not
-specified it defaults to the current branch (HEAD).
+git-rebase replaces <branch> with a new branch of the same name. When
+the --onto option is provided the new branch starts out with a HEAD equal
+to <newbase>, otherwise it is equal to <upstream>. It then attempts to
+create a new commit for each commit from the original <branch> that does
+not exist in the <upstream> branch.
-When git-rebase is complete, <branch> will be updated to point to the
-newly created line of commit objects, so the previous line will not be
-accessible unless there are other references to it already.
+It is possible that a merge failure will prevent this process from being
+completely automatic. You will have to resolve any such merge failure
+and run `git rebase --continue`. If you can not resolve the merge
+failure, running `git rebase --abort` will restore the original <branch>
+and remove the working files found in the .dotest directory.
+
+Note that if <branch> is not specified on the command line, the currently
+checked out branch is used.
Assume the following history exists and the current branch is "topic":
+------------
A---B---C topic
/
D---E---F---G master
+------------
From this point, the result of either of the following commands:
+
git-rebase master
git-rebase master topic
would be:
+------------
A'--B'--C' topic
/
D---E---F---G master
+------------
While, starting from the same point, the result of either of the following
commands:
would be:
+------------
A'--B'--C' topic
/
D---E---F---G master
+------------
In case of conflict, git-rebase will stop at the first problematic commit
-and leave conflict markers in the tree. After resolving the conflict manually
-and updating the index with the desired resolution, you can continue the
-rebasing process with
+and leave conflict markers in the tree. You can use git diff to locate
+the markers (<<<<<<) and make edits to resolve the conflict. For each
+file you edit, you need to tell git that the conflict has been resolved,
+typically this would be done with
+
+
+ git update-index <filename>
+
+
+After resolving the conflict manually and updating the index with the
+desired resolution, you can continue the rebasing process with
+
+
+ git rebase --continue
- git am --resolved --3way
Alternatively, you can undo the git-rebase with
- git reset --hard ORIG_HEAD
- rm -r .dotest
+
+ git rebase --abort
OPTIONS
-------
<branch>::
Working branch; defaults to HEAD.
+--continue::
+ Restart the rebasing process after having resolved a merge conflict.
+
+--abort::
+ Restore the original branch and abort the rebase operation.
+
+NOTES
+-----
+When you rebase a branch, you are changing its history in a way that
+will cause problems for anyone who already has a copy of the branch
+in their repository and tries to pull updates from you. You should
+understand the implications of using 'git rebase' on a repository that
+you share.
+
+When the git rebase command is run, it will first execute a "pre-rebase"
+hook if one exists. You can use this hook to do sanity checks and
+reject the rebase if it isn't appropriate. Please see the template
+pre-rebase hook script for an example.
+
+You must be in the top directory of your project to start (or continue)
+a rebase. Upon completion, <branch> will be the current branch.

USAGE='[--onto <newbase>] <upstream> [<branch>]'
-LONG_USAGE='git-rebase applies to <upstream> (or optionally to <newbase>) commits
-from <branch> that do not appear in <upstream>. When <branch> is not
-specified it defaults to the current branch (HEAD).
-
-When git-rebase is complete, <branch> will be updated to point to the
-newly created line of commit objects, so the previous line will not be
-accessible unless there are other references to it already.
-
-Assuming the following history:
-
- A---B---C topic
- /
- D---E---F---G master
-
-The result of the following command:
-
- git-rebase --onto master~1 master topic
-
- would be:
-
- A'\''--B'\''--C'\'' topic
- /
- D---E---F---G master
+LONG_USAGE='git-rebase replaces <branch> with a new branch of the
+same name. When the --onto option is provided the new branch starts
+out with a HEAD equal to <newbase>, otherwise it is equal to <upstream>
+It then attempts to create a new commit for each commit from the original
+<branch> that does not exist in the <upstream> branch.
+
+It is possible that a merge failure will prevent this process from being
+completely automatic. You will have to resolve any such merge failure
+and run git-rebase --continue. If you can not resolve the merge failure,
+running git-rebase --abort will restore the original <branch> and remove
+the working files found in the .dotest directory.
+
+Note that if <branch> is not specified on the command line, the
+currently checked out branch is used. You must be in the top
+directory of your project to start (or continue) a rebase.
+
+Example: git-rebase master~1 topic
+
+ A---B---C topic A'\''--B'\''--C'\'' topic
+ / --> /
+ D---E---F---G master D---E---F---G master
