I also posted to the github gist, this the sed command here is not cross-platafo...

The bit at the end isn't POSIX sh, either. Fixed version:

if [ $# -eq 0 ] || [ "$1" = "-h" ]; then help exit 1 fi

Relevant spec bits:

This also strips the leading hashes + optional space:

    awk 'sub("^### ?","")' "$0"

sed -n '/^###/p' is cross-platform friendly.

This will also work:

  sed '/^###/!d'

pwdisswordfish2 · on July 8, 2020

This will also work:

   sed '/^#\{3\}/!d'

Nice, this is much cleaner
