====== rebase ======

===== Edit, Move, Delete commits =====

<code bash>
git rebase -i #rewrite all commits in this branch
git rebase -i HEAD~3 # rewrite last 3 commits in this branch
</code>

This will open the default text editor with the specified commits.

__NOTE__ that the order differs from the log. This order is chronological from top to bottom.

<code bash>
pick f7f3f6d changed my name a bit
pick 310154e updated README formatting and added blame
pick a5f4a0d added cat-file

# Rebase 710f0f8..a5f4a0d onto 710f0f8
#
# Commands:
#  p, pick = use commit
#  e, edit = use commit, but stop for amending
#  s, squash = use commit, but meld into previous commit
#
# If you remove a line here THAT COMMIT WILL BE LOST.
# However, if you remove everything, the rebase will be aborted.
#
</code>

Then you can replace all the first word / action at each line, which will make what you want.

  * **pick** the commit will be moved where you specify.\\ 
  * **edit** the rebase will be stopped at this commit, making possible to submit any changes to it, adding, removing files, and then you must submit **git commit --amend**, finally then you can edit the message. Finally you must type **git rebase --continue**
  * **squash** the commit will be merged with its precedent

===== Change the date of a commit =====
To modify the timestamp of a commit while rebasing:
<code>
export newDate="`date`"
GIT_COMMITTER_DATE="$newDate" git commit --amend --no-edit --date "$newDate" && git rebase --continue
</code>

Or as a single command:
<code>
GIT_COMMITTER_DATE=(date) git commit --amend --no-edit --date "$GIT_COMMITTER_DATE"
</code>
