要统计给定作者(或所有作者)在给定分支上提交的数量，可以使用git-shortlog;特别是它的——编号和——摘要选项，例如在git存储库上运行时:

$ git shortlog v1.6.4 --numbered --summary

到目前为止，我确定的最好的工具是gitinspector。它给每个用户，每周等设置报告 你可以像下面这样用npm安装

NPM install -g gitinspector

这些链接可以获得更多详细信息

https://www.npmjs.com/package/gitinspector

https://github.com/ejwa/gitinspector/wiki/Documentation

https://github.com/ejwa/gitinspector

命令示例如下

gitinspector -lmrTw 
gitinspector --since=1-1-2017 etc

下面是一个简短的一行代码，用于生成所有作者的统计信息。它比Dan在https://stackoverflow.com/a/20414465/1102119上的解决方案快得多(我的解决方案的时间复杂度是O(N)，而不是O(NM)，其中N是提交的数量，M是作者的数量)。

git log --no-merges --pretty=format:%an --numstat | awk '/./ && !author { author = $0; next } author { ins[author] += $1; del[author] += $2 } /^$/ { author = ""; next } END { for (a in ins) { printf "%10d %10d %10d %s\n", ins[a] - del[a], ins[a], del[a], a } }' | sort -rn

我对上面的一个简短的回答作了修改，但这不足以满足我的需要。我需要能够对提交的行和最终代码中的行进行分类。我还想按文件进行细分。这段代码不递归，它只返回单个目录的结果，但如果有人想进一步了解，这是一个很好的开始。复制并粘贴到文件中并使其可执行或使用Perl运行。

我编写了这个Perl脚本来完成这项任务。

#!/usr/bin/env perl

use strict;
use warnings;

# save the args to pass to the git log command
my $ARGS = join(' ', @ARGV);

#get the repo slug
my $NAME = _get_repo_slug();

#get list of authors
my @authors = _get_authors();
my ($projectFiles, $projectInsertions, $projectDeletions) = (0,0,0);
#for each author
foreach my $author (@authors) {
  my $command = qq{git log $ARGS --author="$author" --oneline --shortstat --no-merges};
  my ($files, $insertions, $deletions) = (0,0,0);
  my @lines = `$command`;
  foreach my $line (@lines) {
    if ($line =~ m/^\s(\d+)\s\w+\s\w+,\s(\d+)\s\w+\([\+|\-]\),\s(\d+)\s\w+\([\+|\-]\)$|^\s(\d+)\s\w+\s\w+,\s(\d+)\s\w+\(([\+|\-])\)$/) {
      my $lineFiles = $1 ? $1 : $4;
      my $lineInsertions = (defined $6 && $6 eq '+') ? $5 : (defined $2) ? $2 : 0;
      my $lineDeletions = (defined $6 && $6 eq '-') ? $5 : (defined $3) ? $3 : 0;
      $files += $lineFiles;
      $insertions += $lineInsertions;
      $deletions += $lineDeletions;
      $projectFiles += $lineFiles;
      $projectInsertions += $lineInsertions;
      $projectDeletions += $lineDeletions;
    }
  }
  if ($files || $insertions || $deletions) {
    printf(
      "%s,%s,%s,+%s,-%s,%s\n",
      $NAME,
      $author,
      $files,
      $insertions,
      $deletions,
      $insertions - $deletions
    );
  }
}

printf(
  "%s,%s,%s,+%s,-%s,%s\n",
  $NAME,
  'PROJECT_TOTAL',
  $projectFiles,
  $projectInsertions,
  $projectDeletions,
  $projectInsertions - $projectDeletions
);

exit 0;

#get the remote.origin.url joins that last two pieces (project and repo folder)
#and removes any .git from the results. 
sub _get_repo_slug {
  my $get_remote_url = "git config --get remote.origin.url";
  my $remote_url = `$get_remote_url`;
  chomp $remote_url;

  my @parts = split('/', $remote_url);

  my $slug = join('-', @parts[-2..-1]);
  $slug =~ s/\.git//;

  return $slug;
}

sub _get_authors {
  my $git_authors = 'git shortlog -s | cut -c8-';
  my @authors = `$git_authors`;
  chomp @authors;

  return @authors;
}

我将其命名为git-line-changes-by-author，并放入/usr/local/bin。因为它保存在我的路径中，所以我可以在2020-01-01之后发出命令git line-changes-by-author—before 2018-12-31—以获得2019年的报告。举个例子。如果我拼错了名字，git会建议正确的拼写。

你可能想要调整_get_repo_slug子只包括remote.origin.url的最后一部分，因为我的回购保存为项目/回购，而你的可能不是。
