font matter

Many static site generators, such as hugo, use yaml at the top of markdown files to provide metadata (author, date, draft status, etc). Front matter begins with a line containing --- and ends when a matching line is found. Here's a neat script I wrote to strip yaml front matter from a directory of markdown files:

#!/bin/sh

for file in data/*.md; do
  sed -i '1 { /^---/ { :a N; /\n---/! ba; d} }' "$file"
  tail -n +2 "$file" > "$file.tmp" && mv "$file.tmp" "$file"
done
