git的分支与合并的两种方法
git add -A和 git add . git add -u在功能上看似很相近,但还是存在一点差别
git add . :他会监控工作区的状态树,使用它会把工作时的所有变化提交到暂存区,包括文件内容修改(modified)以及新文件(new),但不包括被删除的文件。
git add -u :他仅监控已经被add的文件(即tracked file),他会将被修改的文件提交到暂存区。add -u 不会提交新文件(untracked file)。(git add --update的缩写)
git add -A :是上面两个功能的合集(git add --all的缩写)
下面是具体操作例子,方便更好的理解(Git version 1.x):
git init echo Change me > change-me echo Delete me > delete-me git add change-me delete-me git commit -m initial echo OK change-me rm delete-me echo Add me > add-me git status # Changed but not updated: # modified: change-me # deleted: delete-me # Untracked files: # add-me git add . git status # Changes to be committed: # new file: add-me # modified: change-me # Changed but not updated: # deleted: delete-me git reset git add -u git status # Changes to be committed: # modified: change-me # deleted: delete-me # Untracked files: # add-me git reset git add -A git status # Changes to be committed: # new file: add-me # modified: change-me # deleted: delete-me
总结:
- · git add -A 提交所有变化
- · git add -u 提交被修改(modified)和被删除(deleted)文件,不包括新文件(new)
- · git add . 提交新文件(new)和被修改(modified)文件,不包括被删除(deleted)文件
git版本不同会有所区别:
Git Version 1.x:
Git Version 2.x:
