Export a series of git commits into patches.

export-git-patches.sh

# Inspired by http://blog.worldofcoding.com/2013/03/formatting-git-patches-for-partially.html
# This calls git log to get a list of commits that affect a certain file pattern and then exports each of them into a file
# If the exported commits shall be limited to these files, another pathspec could be added in the second git log call.

# The code is split into several lines to make it more readable, but all ";" are there such that all line breaks could be removed.

c=0;
git log --oneline --reverse -- your/pathspec.* |cut -d' ' -f1 | while read a; 
do 
  c=$[c+1];
  n=$(printf "%04d\n" $c); 
  git log -p --pretty=email --stat -m --first-parent $a~1..$a > $n-$a.patch; 
done
