Piping output of `beet ls -p`

Adrian, in the introductory video (2:11) you claim that the beet ls -p command allows you to “[…] pipe into a different Unix utility […]”

Yet on macOS, none of the following yielded any results:
beet ls -p "supersong" | exiftool
beet ls -p "supersong" | mediainfo
beet ls -p "supersong" | less

What am I missing?

Hmm; less should probably work! But perhaps you’re interested in xargs?

You are right; less did display the path found by beet ls -p, but not its contents, which is what I would expect.

This works:
beet ls -p "supersong" | xargs -I{} mediainfo {}
