git commit stats
Commands to get commit statistics for a Git repository from the command line -
using git log, git shortlog and friends.
List repository contributors by author name (sorted by name):
$ git log --format='%aN' | sort -u
Example output:
Jane Bar
John Foo
Steve Baz
List total commits by author (sorted by commit count):
$ git shortlog -sn
Example output:
136 Jane Bar
41 John Foo
17 Steve Baz
Ignore merge commits:
$ git shortlog -sn --no-merges
Example output:
121 Jane Bar
36 John Foo
14 Steve Baz
Even though the --no-merges option is not documented for git shortlog, it works exactly as defined for git log.
List file change stats by author:
$ git log --author="Vorname Nachname" --pretty=tformat: --numstat | awk '{inserted+=$1; deleted+=$2; delta+=$1-$2; ratio=deleted/inserted} END {printf "Commit stats:\n- Lines added (total).... %s\n- Lines deleted (total).. %s\n- Total lines (delta).... %s\n- Add./Del. ratio (1:n).. 1 : %s\n", inserted, deleted, delta, ratio }' -
Example output:
Commit stats:
- Lines added (total).... 4625
- Lines deleted (total).. 836
- Total lines (delta).... 3789
- Add./Del. ratio (1:n).. 1 : 0.180757
Include file count:
$ git log --shortstat --author="Vorname Nachname" | grep -E "fil(e|es) changed" | awk '{files+=$1; inserted+=$4; deleted+=$6; delta+=$4-$6; ratio=deleted/inserted} ...
