如何获得文件所有权，即每个开发人员为应用程序的每次提交添加的代码行

Question

I tried below statement

git blame --line-porcelain file | sed -n 's/^author //p' |sort | uniq -c | sort -rn

but this statement gives for the latest commit . I need for each and every commit for a particular file.

Please suggest !!

Answer 1

You can use this sequence

git log --reverse --oneline filename | awk '{ print $1; }'| while read c
do echo "authors for commit $c:"
    git blame --line-porcelain filename $c | grep "^author " | sort | uniq -c | sort -nr
done

As I told you: This is a multi dimensional thing with coordinates (filename, commit, author, number of lines) . First think about how you want to display or store the output. Also note that git blame is not about added lines but changed lines. So if someone deleted a file with 10k lines, he/she will get noted as a changer of 10k lines, though the statement was just rm file .

Number of Lines changed is generally a very bad parameter to measure code or work done on some code. Sometimes an author that thinks a week over his code and then changes one line, improving the speed of the program by a factor of 1000 is a much worthier author than this guy last week, who wrote 5000 lines of spagetthi code.

But this information is redundant. Better use

git log -p --reverse filename

and learn to read patch files.
