今天遇到一个场景：在rebase其他同事的分支时，带来了一些脏提交，然而由于同事暂时无法处理，所以需要先将这几个提交抽离出来，简单来说是这样↓
commit 我的提交5
commit 我的提交4
commit 同事的脏提交3
commit 同事的脏提交2
commit 同事的正常提交1
commit 同事的正常提交0
需要将commit 2和commit 3先抽离丢弃，等待修复后再重新rebase他的分支
其中，抽离丢弃的过程如下：
# 假设git log结果如下

选中脏提交的上一个提交的commit id，在这里对应的是“正常提交1”，即9c583f3e86845f26892dad238294c78d8f389a40，执行git rebase -i 9c583f3e86845f26892dad238294c78d8f389a40
pick 7325967 脏提交2
pick a5122cd 脏提交3
pick 33dc720 我的提交4
pick 77df905 我的提交5
# Rebase 9c583f3..77df905 onto 77df905 (4 commands)
#
# Commands:
# p, pick <commit> = use commit
# r, reword <commit> = use commit, but edit the commit message
# e, edit <commit> = use commit, but stop for amending
# s, squash <commit> = use commit, but meld into previous commit
# f, fixup <commit> = like "squash", but discard this commit's log message
# x, exec <command> = run command (the rest of the line) using shell
# b, break = stop here (continue rebase later with 'git rebase --continue')
# d, drop <commit> = remove commit
# l, label <label> = label current HEAD with a name
# t, reset <label> = reset HEAD to a label
# m, merge [-C <commit> | -c <commit>] <label> [# <oneline>]
# . create a merge commit using the original merge commit's
# . message (or the oneline, if no original merge commit was
# . specified). Use -c <commit> to reword the commit message.
#
# These lines can be re-ordered; they are executed from top to bottom.
#
# If you remove a line here THAT COMMIT WILL BE LOST.
#
# However, if you remove everything, the rebase will be aborted.
#
# Note that empty commits are commented out
根据提示 # If you remove a line here THAT COMMIT WILL BE LOST. 只需要删掉脏提交的那几行然后保存即可
# 保留以下几行，其他注释掉或删掉，保存
pick 33dc720 我的提交4
pick 77df905 我的提交5
假设没有冲突的情况下，git log会变成这样
