对于一个文件:

git diff --no-index /dev/null new_file

对于所有新文件:

for next in $( git ls-files --others --exclude-standard ) ; do git --no-pager diff --no-index /dev/null $next; done;

别名:

alias gdnew="for next in \$( git ls-files --others --exclude-standard ) ; do git --no-pager diff --no-index /dev/null \$next; done;"

对于所有修改和新文件组合为一个命令:

{ git --no-pager diff; gdnew }

使用git stash Hack:

# Stash unstaged changes
git stash --keep-index --include-untracked --message="pre-commit auto-stash"
git stash show --only-untracked stash@{0}
git stash pop

我需要在使用git stash(即预提交git钩子)的脚本上下文中使用这个。以下是我的完整工作示例: (在macOS Big Sur上的git v2.34.1上编写/测试)

# Stash unstaged changes
# NOTE: we always create a stash - possibly even a totally empty one.
git stash --keep-index --include-untracked --message="pre-commit auto-stash"
diffTracked=$(git diff --stat --staged stash@{0})
diffUntracked=$(git stash show --only-untracked stash@{0})
[[ $diffTracked || $diffUntracked ]] && {
  echo "Stashed diff:"
  # Ensure diffs have standard coloring:
  git diff --stat --staged stash@{0}
  git stash show --only-untracked stash@{0}
}

这对我来说很管用:

git add my_file.txt
git diff --cached my_file.txt
git reset my_file.txt

最后一步是可选的，它将使文件保持之前的状态(未跟踪)

如果你正在创建一个补丁也有用:

  git diff --cached my_file.txt > my_file-patch.patch

git add -A
git diff HEAD

生成补丁，如果需要，然后:

git reset HEAD

我相信您可以通过简单地提供两个文件的路径来区分索引文件和未跟踪文件中的文件。

git diff --no-index tracked_file untracked_file

对于一个文件:

git diff --no-index /dev/null new_file

对于所有新文件:

for next in $( git ls-files --others --exclude-standard ) ; do git --no-pager diff --no-index /dev/null $next; done;

别名:

alias gdnew="for next in \$( git ls-files --others --exclude-standard ) ; do git --no-pager diff --no-index /dev/null \$next; done;"

对于所有修改和新文件组合为一个命令:

{ git --no-pager diff; gdnew }
