curl -sL frew.co | docker run -i --rm frew/hq '//head/title/text()'
hq is a commandline tool built in the
spirit of jq but for HTML. Use this
container if you don't like having to deal with pip and whatnot.
There are no volumes or environment variables expected. While the -f hq
flag is unsupportable without a volume, you can just implement that with <,
which is fewer characters and simpler anyway.
