• git rebase basics 2 answers

simply, i've done :

a------b-------c         \          \           b2 

now, want change b b2.

a------b2-------c 

is possible?

solution history:

i added work history.

$ git log commit b671c70b c commit f4acdc2b b commit 56f38939  $ git checkout f4acdc2b  

and modified something... committed -amend option.

$ git commit -amend $ git log commit e2fd729 b' commit 56f3893 

now, became this:

a------b-------c         \          \           b' 

to rebasing b b'

$ git checkout b671c70b $ git rebase -i 56f38939 

which opens interactive editor

pick f4acdc2b b pick 56f38939 

just remove line pick f4acdc2b, save , quit.

if there error error: not apply b671c70b... c, edit merge conflicts , then,

$ git add . $ git rebase --continue  $ git log commit 914c6bc c' commit 56f3893  $ git checkout 914c6bc $ git rebase e2fd729  $ git log commit 5c65190 c'' commit e2fd729 b' commit 56f3893 

now, looks this.

a------b'-------c'' 

you interactively rebase branch on top of b2 (on top of a actually, since want b2 gone):

 git checkout yourbranch # references c)  git rebase -i  # drop b 

that give:

 a------b2'-------c' 

(note c' c different sha1, since parent has changed)
(same comment b2, since parent changed)
