--amend

    Used to amend the tip of the current branch. Prepare the tree
object you would want to replace the latest commit as usual (this
includes the usual -i/-o and explicit paths), and the commit log
editor is seeded with the commit message from the tip of the current
branch. The commit you create replaces the current tip — if it was a
merge, it will have the parents of the current tip as parents — so the
current top commit is discarded.

    It is a rough equivalent for:

            $ git reset --soft HEAD^
            $ ... do something else to come up with the right tree ...
            $ git commit -c ORIG_HEAD

    but can be used to amend a merge commit.





I find myself wanting to amend not tip of the branch, but an older
commit (typically to change log message). As example if I have this


D---E---F---G master

And I want to amend revision E currently I do

            $ git branch tmp
            $ git reset E
            $ git commit --amend
            $ git rebase tmp master
            $ git branch -d tmp


Would be possible to extend git commit --amend so to automate the
above sequence ? Or does perhaps exists a better sequence to change
(actually simulate the change of) log message of an inner revision?

Thanks in advance
Marco

git rebase --interactive E^
Then change the commit for E from 'pick' to 'edit'.
Then follow the directions.

git rebase -i E^

Then, change a "pick" with a "edit" wherever you want.

(Perhaps the doc of commit --amend could say "to amend a previous
commit, you may want to look at the 'edit' command of 'git rebase
-i'"?)
