Count number of code lines in git repository per user

Count Code lines

git ls-files -z | xargs -0n1 git blame -w | perl -n -e '/^.*\((.*?)\s*[\d]{4}/; print $1,"\n"' | sort -f | uniq -c | sort -n

Here's a variation on the earlier responses that parallelizes the blame. This can result in a significant speedup if you have multiple cores. This version also supports filenames that may be quoted by 'git ls-files' (tabs, newlines, backslashes, quotes, UTF-8, etc.) or that begin with a "-":

git ls-files -z |
   xargs -0rn 1 -P "$(nproc)" -I{} sh -c 'git blame -w -M -C -C --line-porcelain -- {} | grep -I --line-buffered "^author "' |
   sort -f |
   uniq -ic |
   sort -n

Hello,

Is there any way to count month wise data like from Jan - Mar how many number of code lines in git repository per user?

The other commands here took hours for our project. Here is a faster method:

1. Remember to use blame.ignoreRevsFile to ignore mass-edits (like code style fixes).
2. Use `git ls-files -x "*pdf" -x "*xml"`` to filter out files.

git ls-files | while read i; do git blame $i | sed -e 's/^[^(]*(//' -e 's/^\([^[:digit:]]*\)[[:space:]]\+[[:digit:]].*/\1/' -e 's/[[:blank:]]*$//'; done | sort -f | uniq -ic | sort -rn

Counting only activity last two years:

git ls-files | while read i; do git blame $i --since 2.years | grep -v '^\^' | sed -e 's/^[^(]*(//' -e 's/^\([^[:digit:]]*\)[[:space:]]\+[[:digit:]].*/\1/' -e 's/[[:blank:]]*$//'; done | sort -f | uniq -ic | sort -rn

Solution modified from: https://stackoverflow.com/a/2788077

here's my one-liner:

function gitfilecontributors() { local perfile="false" ; if [[ $1 = "-f" ]]; then perfile="true" ; shift ; fi ; if [[ $# -eq 0 ]]; then echo "no files given!" >&2 ; return 1 ; else local f ; { for f in "$@"; do echo "$f" ; git blame --show-email "$f" | sed -nE 's/^[^ ]* *.<([^>]*)>.*$/: \1/p' | sort | uniq -c | sort -r -nk1 ; done } | if [[ "$perfile" = "true" ]]; then tee /tmp/gitblamestats.txt ; else tee /tmp/gitblamestats.txt >/dev/null ; fi ; echo ; echo "total:" ; awk -v FS=' *: *' '/^ *[0-9]/{sums[$2] += $1} END { for (i in sums) printf("%7s : %s\n", sums[i], i)}' /tmp/gitblamestats.txt | sort -r -nk1 ; fi ; }

or with line breaks:

gitfilecontributors ()
{
    local perfile="false";
    if [[ $1 = "-f" ]]; then
        perfile="true";
        shift;
    fi;
    if [[ $# -eq 0 ]]; then
        echo "no files given!" 1>&2;
        return 1;
    else
        local f;
        {
            for f in "$@";
            do
                echo "$f";
                git blame --show-email "$f" | sed -nE 's/^[^ ]* *.<([^>]*)>.*$/: \1/p' | sort | uniq -c | sort -r -nk1;
            done
        } | if [[ "$perfile" = "true" ]]; then
            tee /tmp/gitblamestats.txt;
        else
            tee /tmp/gitblamestats.txt > /dev/null;
        fi;
        echo;
        echo "total:";
        awk -v FS=' *: *' '/^ *[0-9]/{sums[$2] += $1} END { for (i in sums) printf("%7s : %s\n", sums[i], i)}' /tmp/gitblamestats.txt | sort -r -nk1;
    fi
}

usage possible four folder(s) of your choice.

option -f to show per file, otherwise totals only:

$ gitfilecontributors    $(fd --type f '.*' source)

total:
    139 : somebody@somewhere.de
     29 : else.user@somewhere.de
      9 : just.another@somewhere.de

gitfilecontributors -f $(fd --type f '.*' source)

source/040_InitialSetup.md
     80 : somebody@somewhere.de
     29 : else.user@somewhere.de
      6 : just.another@somewhere.de
README.md
     59 : somebody@somewhere.de
      5 : whosthat@somewhere.de
      3 : just.another@somewhere.de

total:
    139 : somebody@somewhere.de
     29 : else.user@somewhere.de
      9 : just.another@somewhere.de
      5 : whosthat@somewhere.de
