Cool! I'll have to drop by sometime. I've been moving to use Raku in
place of shell scripts or commands more often. A short time ago I wanted
to get a list of directories along with the total page count of all PDF
files within them, sorted by the page counts, and I was able to do it with
a short-ish Raku one-liner (broken into multiple lines here for clarity):
.say for sort dir.map: {
run('exiftool', .dir.grep(/'.pdf'$/), :out)
.out.slurp.match(:g, /^^ 'Page Count' \N+? <( \d+ $$/).sum => ~$_ if .d
}
The one thing that's hardest for me to keep in mind is to use "\N" instead
of ".", which here silently produces dramatically wrong results.
