A number of static site generators use front matter. This script would be handy to update the front matter labels. Run this from within posts folder to prepend first and second lines with `title =` and `date =` respectively.

fm1.sh

for f in *;
  do sed '1i\
  title: ' < $f > tmp_$f ;
  mv tmp_$f $f ;
done

for f in *;
  do sed '2i\
  date: ' < $f > tmp_$f ;
  mv tmp_$f $f ;
done

for f in *;
  do sed '3i\
  tags: ' < $f > tmp_$f ;
  mv tmp_$f $f ;
done

for f in *;
  do sed '3G' < $f > tmp_$f ;
  mv tmp_$f $f ;
done

for f in *;
  do echo "---\n$(cat $f)" > $f;
done

fm2.sh

for f in *;
  do sed '4G' < $f > tmp_$f ;
  mv tmp_$f $f ;
done

for f in *;
  do sed '5i\
  ---' < $f > tmp_$f ;
  mv tmp_$f $f ;
done

fm3.sh

# Update date line
for f in *;
  do sed -E 's,([0-9]{2})/([0-9]{2})/([0-9]{4}),\3-\1-\2,g' < $f > tmp_$f ;
  mv tmp_$f $f ;
done

fm4.sh

# Append timestap to date line
for f in *;
  do sed '3s/$/T21:00:00+05:30/' < $f > tmp_$f ;
  mv tmp_$f $f ;
done

frontmatter.md

Add frontmatter to posts written for Chisel to be compatible with Jekyll or Hugo

Two scripts to run one after the other in the order shown:

cd posts
sh ../fm1.sh
