Usage

Usage: metagrep [options] pattern [flac_dir]

Options

• Option	Description	Default
  --help	Display this help message.
  --[no]insensitive	Case-insensitive pattern matching.	noinsensitive
  --[no]invert	Show tracks that do not have matching pattern.	noinvert
  --[no]listonly	Only display name of matching files.	nolistonly

  --quiet	Quiet operation, no screen output.

Patterns

The pattern you provide is a standard Perl regular expression. Metadata tags are represented in FLAC files as name=value pairs. The entire tag is matched against the pattern.

Examples

Search for tracks where track number is 1:

• metagrep ^TRACKNUMBER=1$

Search for tracks with the word "love" in the track title (case insensitive):

• metagrep --insensitive ^TITLE=.*love

List tracks with the title "Rhapsody in Blue":

• metagrep --listonly "^TITLE=Rhapsody in Blue$"

Search for tracks with a MusicBrainz track identifier:

• metagrep ^MUSICBRAINZ_TRACKID=

Search for tracks with a MusicIP PUID:

• metagrep ^MUSICIP_PUID=

Search for tracks missing a MusicIP PUID:

• metagrep --invert ^MUSICIP_PUID=

Configuration file

You can store persistent command-line options in a file called .metagrep in your home directory. They will be read as defaults prior to processing any passed command-line options.
