根据您是否希望包含二进制文件，有两种解决方案。

git grep --cached -al '' | xargs -P 4 cat | wc -l git grep --cached -Il '' | xargs -P 4 cat | wc -l "xargs -P 4" means it can read the files using four parallel processes. This can be really helpful if you are scanning very large repositories. Depending on capacity of the machine you may increase number of processes. -a, process binary files as text (Include Binary) -l '', show only filenames instead of matching lines (Scan only non empty files) -I, don't match patterns in binary files (Exclude Binary) --cached, search in index instead of in the work tree (Include uncommitted files)

Xargs会让你把所有文件放在一起，然后把它们传递给wc，就像你问的那样:

git ls-files | xargs cat | wc -l

但是跳过中间的cat会给你更多的信息，可能会更好:

git ls-files | xargs wc -l

: | git mktree | git diff --shortstat --stdin

Or:

git ls-tree @ | sed '1i\\' | git mktree --batch | xargs | git diff-tree --shortstat --stdin

我是这样做的:

git ls-files | xargs file | grep "ASCII" | cut -d : -f 1 | xargs wc -l

如果将存储库中的所有文本文件都计算为感兴趣的文件，那么这是可行的。如果其中一些被认为是文档等，则可以添加排除过滤器。

git diff --stat 4b825dc642cb6eb9a060e54bf8d69288fbee4904

这显示了从空树到当前工作树的差异。它恰好计算当前工作树中的所有行。

要获得当前工作树中的数字，请执行以下操作:

git diff --shortstat `git hash-object -t tree /dev/null`

它会给你一个字符串，比如1770 files changed, 166776 insertions(+)。
