请cd到指定代码仓库目录下，然后运行上面的命令，可以看到如下输出，
peipeihh 13594 275 13869
每列的数字意义如下，
第一列：代码提交人
第二列：提交的新增代码行数
第三列：提交的删除代码行数
第四列：所有提交的代码行数
2. 批量的Git代码仓库
若是有批量的Git代码仓库，则可以使用如下批量分析脚本。
# 1. parse the date of start and end
sinceDate=$1
untilDate=$2
if [ ! $sinceDate ]; then
sinceDate="1970-01-01"
fi
if [ ! $untilDate ]; then
untilDate=`date '+%Y-%m-%d'`
fi
echo "the period of analysis: sinceDate = $sinceDate, untilDate = $untilDate"
# 2. prepare the repository folder
repoTmp=$PWD
repoList="$PWD/repoList.txt"
repoLocalDir="$PWD/repoLocal"
repoReportFile="$PWD/tmpReport.txt"
repoFinalReportFile="$PWD/finalReport.txt"
if [ -d "$repoLocalDir" ]; then
rm -rf $repoLocalDir;
fi
mkdir -p $repoLocalDir;
if [ -f "$repoReportFile" ]; then
rm $repoReportFile;
fi
touch $repoReportFile;
if [ ! -f "$repoList" ]; then
echo "Cannot find repoList.txt, please create it and list all the git repositories to be analyzed, a format is as following, "
echo "```"
echo "git@gitee.com:pphh/simple-demo.git master"
echo "```"
exit 1
fi
# 3. clone the git repo into local and do the investigation
i=1
cat $repoList | while read line
do
cd $repoLocalDir
repoDef=( $line )
repoName=${repoDef[0]}
repoBranch=${repoDef[1]}
if [ -z $repoName ]; then
continue
fi
if [ -z $repoBranch ]; then
repoBranch="master"
fi
repoFolder="./$i-repo-$repoBranch"
let i++
echo
echo "start to clone the repository: $repoName, branch = $repoBranch, folder = $repoFolder"
git clone $repoName -b $repoBranch $repoFolder
echo "clone is completed!"
cd $repoFolder
echo "try to investigate the submission status of the repository: $repoName, branch = $repoBranch"
git log --format='%aN' | sort -u | while read name; do git log --numstat --author="$name" --since="$sinceDate" --until="$untilDate" | awk 'BEGIN {add=0;subs=0;all=0} {if($1~/^[0-9]+/){add += $1; subs += $2; all += $1 + $2 }} END {printf "'$name'\t%s\t%s\t%s\n", add, subs, all }' >> $repoReportFile; done;
done
# 4. merge the results
cat $repoReportFile | awk '{ newLines[$1]+=$2;deleteLines[$1]+=$3;all[$1]+=$4 } END {for (i in all) print i,newLines[i],deleteLines[i],all[i];}' > $repoFinalReportFile
rm $repoReportFile
