Git:常用功能 - 命令行

　　1. 正在某个分支进行开发，突然有个紧急BUG需要切换到其他分支进行修复？

git add README.md # 将文件添加到暂存区

git stash save "v1.0.0 in development" # 贮藏暂存区的修改

# do something in other branch & checkout previous branch

git stash list # 显示贮藏列表
# output:"stash@{0}: On master: v1.0.0 in development"

git stash pop stash@{} # 应用贮藏的修改

2. 提交了N个版本后发现代码有问题，想重置代码到某个版本？

git log --pretty=format:"%h %an %ar: %s" # 输出日志，格式：提交的简短哈希值 作者 提交时间 提交
# output:"
ac4b4fc YaungOu  minutes ago: fix(bug-): fix something
868e045 YaungOu  minutes ago: fix(bug-): fix something
aa13e9b YaungOu  minutes ago: fix(bug-): fix something
4169d73 YaungOu  minutes ago: fix(bug-): fix something
a142e95 YaungOu  minutes ago: fix(bug-): fix something
c221ede YaungOu  minutes ago: init
"

git reset --hard 868e045 # 重置提交历史到该版本，并丢弃所有修改

　　

　　3. 重置代码到某个版本，不小把有用的提交也重置？

git reflog # 查看所有操作记录(包括reset操作)
# output:"
868e045 HEAD@{}: reset: moving to 868e045
ac4b4fc HEAD@{}: commit: fix(bug-): fix something
868e045 HEAD@{}: commit: fix(bug-): fix something
aa13e9b HEAD@{}: commit: fix(bug-): fix something
4169d73 HEAD@{}: commit: fix(bug-): fix something
a142e95 HEAD@{}: commit: fix(bug-): fix something
c221ede HEAD@{}: commit (initial): init
"

git branch resume-master ac4b4fc # 基于某个版本创建新的分支

# 合并分支或者创建、应用补丁

　　

　　4. 不小心清空了贮藏的修改（贮藏也要好好写备注喔(●'◡'●)，不然想搜索也难）

git fsck --lost-found | awk '{print $3}' | xargs git show | grep -C 5 v1.0.5 # 找回丢失的对象 | 获取对象哈希值 | 显示对象内容 | 根据关键搜索
# output:"
Checking object directories: 100% (256/256), done.
