some stuff I need to incorporate later on:

the blog post-update git hook:



#!/bin/sh
blog_dir=~/blog
export GIT_DIR=$(pwd)
export GIT_WORK_TREE="$blog_dir"
git checkout -f
cd "$GIT_WORK_TREE"
redo
git add metadata/author metadata/url metadata/title metadata/*.tmpl metadata/automatic_metadata captchas/linkable/*
count=$(ls -1 metadata/*.automatic_metadata 2>/dev/null | wc -l)
if [ "$count" != 0 ]; then
  git add metadata/*.automatic_metadata
fi
status=$(git status -s)
n_updates=$(printf "$status" | grep -vE '^\?\?' | wc -l)
if [ "$n_updates" -gt 0 ]; then
  git commit -a -m 'Update metadata'
fi
