本文主要是介绍Git撤消操作，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
十二. Git撤消操作
12.1 修改最后一次提交 git commit --amend
1.新建一个文件 2.提交一个之前的更改
3.跟踪这个文件 4.跟前一次一起提交
提示你是否重新编辑提交说明，如果不编辑退出后还是跟之前一样提交
commit 成功
或 git commit -m “” 可以直接提交
12.2 撤消已暂存的文件 git reset HEAD
#新建两个文件
bixiaopeng@bixiaopengtekiMacBook-Pro wirelessqa$ touch 1txt
bixiaopeng@bixiaopengtekiMacBook-Pro wirelessqa$ touch 2txt
#全部暂存
bixiaopeng@bixiaopengtekiMacBook-Pro wirelessqa$ git add -A
#查看文件状态
bixiaopeng@bixiaopengtekiMacBook-Pro wirelessqa$ git status
# On branch master
# Your branch is ahead of 'origin/master' by 1 commit.
# (use "git push" to publish your local commits)
#
# Changes to be committed:
# (use "git reset HEAD <file>..." to unstage)
#
# new file: 1txt
# new file: 2txt
# #取消暂存 1txt
bixiaopeng@bixiaopengtekiMacBook-Pro wirelessqa$ git reset HEAD 1txt
#再次查看文件状态，1txt 已经被取消啦bixiaopeng@bixiaopengtekiMacBook-Pro wirelessqa$ git status
# On branch master
# Your branch is ahead of 'origin/master' by 1 commit.
# (use "git push" to publish your local commits)
#
# Changes to be committed:
# (use "git reset HEAD <file>..." to unstage)
#
# new file: 2txt
#
# Untracked files:
# (use "git add <file>..." to include in what will be committed)
#
# 1txt 12.3 撤消对文件的修改 git checkout -- <file>
bixiaopeng@bixiaopengtekiMacBook-Pro wirelessqa$ ls
README TEST android-package ios-package testamend
#修改文件testmend
bixiaopeng@bixiaopengtekiMacBook-Pro wirelessqa$ vim testamend
bixiaopeng@bixiaopengtekiMacBook-Pro wirelessqa$ git status
# On branch master
# Your branch is ahead of 'origin/master' by 1 commit.
# (use "git push" to publish your local commits)
#
# Changes not staged for commit:
# (use "git add <file>..." to update what will be committed)
# (use "git checkout -- <file>..." to discard changes in working directory)
#
# modified: testamend
#
no changes added to commit (use "git add" and/or "git commit -a”)
#撤消文件的修改
bixiaopeng@bixiaopengtekiMacBook-Pro wirelessqa$ git checkout -- testamend
bixiaopeng@bixiaopengtekiMacBook-Pro wirelessqa$ git status
# On branch master
# Your branch is ahead of 'origin/master' by 1 commit.
# (use "git push" to publish your local commits)
#
nothing to commit, working directory clean
12.4 Git撤消commit
-
git log查看日志，找到需要回退的那次commit的 哈希值
2. git reset --hard commit_id
12.5 Git版本回退
#查看log
bixiaopeng@bixiaopengtekiMacBook-Pro wirelessqa$ git log

#放弃本地所有修改，回退到上一个版本
bixiaopeng@bixiaopengtekiMacBook-Pro wirelessqa$ git reset --hard HEAD^
HEAD is now at fa7fd8d delete test2
注： --hard 表示放弃所有本地改动
#再次查看log

bixiaopeng@bixiaopengtekiMacBook-Pro wirelessqa$ git reset --hard 746f92258e2bc65c46f77f37315f577091192885
HEAD is now at 746f922 test git commit -a
12.6 撤消未跟踪文件 git clean -dxf
「举个例子」
清除所有未跟踪文件，包括纳入ignored的文件。如果要保留ignored的文件修改，使用参数-df
＃清除所有未跟踪文件，包括纳入ignored的文件
bixiaopeng@bixiaopeng-To-be-filled-by-O-E-M:~/workspace2/spark$ git clean -dxf
正删除 .idea/
正删除 .package.sh.swp
正删除 assets/sparklog/
正删除 backup-config/AndroidManifest.xml
正删除 backup-config/channel_config.xml
正删除 backup-res/assets/
正删除 backup-res/res/
正删除 debug
正删除 package/spark_2.4_L95_91zhuomian.apk
正删除 res/values/channel_config.xmlg
正删除 target/
正删除 xiamimusic.iml
＃再查看一下未跟踪的文件已经被撤消了
bixiaopeng@bixiaopeng-To-be-filled-by-O-E-M:~/workspace2/spark$ git status
# 位于分支 test
# 尚未暂存以备提交的变更：
# （使用 "git add <file>..." 更新要提交的内容）
# （使用 "git checkout -- <file>..." 丢弃工作区的改动）
#
# 修改： pom.xml
#
修改尚未加入提交（使用 "git add" 和/或 "git commit -a"）｀
