git squash (將眾多的Commit 簡略化)
git squash 合併目前的commit
假設我有這麼多commit或更多
* b1b8eq9 - (HEAD -> master) Commit-3
* 57qwqe5 - Commit-2
* e7ada1d - Commit-1
* 5d39f12 - Commit-0
在此的歷史紀錄 commit就很醜陋，接下來讓我們把它變得更簡單吧。
使用git rebase -i 參數稱為squash
-i 實際上就是 --interactive 簡寫 參數代表我們想保留哪個commit
如果我們要保留e7ada1d那就執行:
git rebase -i e7ada1d
也可以透過HEAD~4做指定
git rebase -i HEAD~4
Enter後讓我們進行下一步驟，我們會看到類似這樣的commit紀錄。
pick e7ada1d Commit-1
pick 57qwqe5 Commit-2
pick b1b8eq9 Commit-3
# Rebase 5d39f12..b1b8eq9 onto 5d39ff2 (3 command(s))
#
# Commands:
# p, pick = use commit
# r, reword = use commit, but edit the commit message
# e, edit = use commit, but stop for amending
# s, squash = use commit, but meld into previous commit
# f, fixup = like "squash", but discard this commit's log message
# x, exec = run command (the rest of the line) using shell
#
# 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
squash： 使用該Commit 會被合併到前一個Commit當中
fixup： 就像 squash 那樣，但會拋棄 Commit message(常用)
完成後請存擋 :wq
pick e7ada1d Commit-1
s 57qwqe5 Commit-2
s b1b8eq9 Commit-3
這時候會進入下一個階段
# This is a combination of 3 commits.
# The first commit's message is:
Commit-1
# This is the 2nd commit message:
Commit-2
# This is the 3rd commit message:
Commit-3
# Please enter the commit message for your changes. Lines starting
# with '#' will be ignored, and an empty message aborts the commit.
#
# Date: Tue Jan 5 23:27:22 2016 +0800
接下來請只留你要的一個Commit就好其他可以刪除註解#可以不用理會
修改完成請存擋 :wq
# This is a combination of 3 commits.
# The first commit's message is:
Commit-1
# Please enter the commit message for your changes. Lines starting
# with '#' will be ignored, and an empty message aborts the commit.

# Date: Tue Jan 5 23:27:22 2016 +0800
接下來再看一下我們的log
使用git log查看紀錄即可完成
如果想要修改 Commit message 請使用git commit --amend來進行修改動作
