Git, find out which files have had the most commits

Question

How can I search my git logs to see which files have had the most activity?

Answer 1

Here's a python script that you can pipe the log --numstat output through to get the results:

import sys, re

res = {}

while 1:
    line = sys.stdin.readline()
    if len(line) == 0:
        break;
    m =  re.match("([0-9]+)[ \t]+([0-9]+)[ \t]+(.*)", line)
    if m != None:
        f = m.group(3)
        if f not in res: res[f] = {'add':0, 'rem':0, 'commits':0} 
        res[f]['commits'] += 1
        res[f]['add'] += int(m.group(1))
        res[f]['rem'] += int(m.group(2))

for f in res:
    r = res[f]
    print "%s %s %s %s"%(r['commits'], r['add'], r['rem'], f)

You can modify it as needed to sort/filter how you want.
