Enable the info plugin in your configuration (see Using Plugins) and then type:
$ beet info /path/to/music.flac
and the plugin will enumerate all the tags in the specified file. It also accepts multiple filenames in a single command-line.
You can also enter a query to inspect music from your library:
$ beet info beatles
If you just want to see specific properties you can use the --include-keys option to filter them. The argument is a comma-separated list of simple glob patterns where * matches any string. For example:
$ beet info -i 'title,mb*' beatles
Will only show the title property and all properties starting with mb. You can add the -i option multiple times to the command line.
Additional command-line options include:
- --library or -l: Show data from the library database instead of the files’ tags.
- --summarize or -s: Merge all the information from multiple files into a single list of values. If the tags differ across the files, print [various].
