git add -A 和 git add . 的区别

实践

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
