This AKW script extracts shell code blocks from Markdown files and runs shellcheck on them.
Only fenced code blocks where the info string starts with bash, ksh, zsh, or sh are extracted.
The &| and ENDFILE GNU AWK extensions are used.
If you don't like that, remove the ENDFILE block and replace &| with temporary files.
