#!/usr/bin/env ruby

# Usage: ./git-all-commits ~/source > commits.log
# commits.log will contain all commits in following format:
# repo_name: SHA FIRSTLINE_COMMIT_MSG

require 'pathname'

dir = ARGV.dup.first

# INITIALS = 'zh' # replace with your own
INITIALS = nil # Place initials here

unless INITIALS
  warn "Must place INITIALS on Line 7."
  exit(1)
end

           if Dir.exists?(d) && Dir.exists?(File.join(d, ".git"))
             Dir.chdir(d) do
               log = `git log --oneline`.chomp.split("\n")
               log.map { |l| [d, l].join(": ")}
             end

         end.compact


output.select! { |i| i[/#{INITIALS}/i] }
output.reject! { |i| i.split(" ")[2][/^Merge/]}
puts output.join("\n")

Replace INITIALS with your own, then run like ./git-all-commits ~/source > commits.log
