Sorry for the multi-correction Smilie
The GNU awk version should include always IGNORECASE=1 in order to ignore the case.
Yes that works. But adding the track doesn't work yet because if the tracknumber is empty track isn't in the output. But it detects and displays the right files now.

This should do it (I hope I got the braces right Smilie):
Code:
find -iname '*.mp3' -exec id3 -Rl {} + |
  awk -F: '/filename: / {
    if (f) print fn
    fn = $2; f = x
    }
    /^(((title|a(rtist|lbum)): *(|unknown|track.*))|track:) *$/ {
      f++
      }
    END {  
      if (f) print fn
      }' IGNORECASE=1

Could you post an example output from metaflac at least for two files: one to be printed and another one to be skipped?

Given your metaflac example above, the filename seems to be missing in the output, this means that we should process the files one by one, in order to get the name ...

This doesn't work yet. This is the output of a mp3 that should be detected, since the tracknumber isn't filled:
Code:
$ id3 -Rl alex\ roeka\ -\ 1999\ \ -\ wildernis/04\ -\ Alex\ Roeka\ -\ Help\ me\,\ ik\ ben\ echt.mp3 

Filename: alex roeka - 1999  - wildernis/04 - Alex Roeka - Help me, ik ben echt.mp3
Title: Help Me, Ik Ben Echt          
Artist: Alex Roeka                    
Album: Wildernis                     
Year:     
Genre: Other (12)
Comment: Het~Nachtdier

This FLAC is ok:
Code:
$ metaflac --export-tags-to=- 06.\ Diseases\ of\ The\ Band.flac 
ARTIST=Frank Zappa
TITLE=Diseases of The Band
ALBUM=You Can't Do That On Stage Anymore, Vol. 1, Disc 1
DATE=1988
TRACKNUMBER=06
GENRE=Rock
COMMENT=Track 6

These FLAC's are not ok:
Code:
$ metaflac --export-tags-to=- 01.\ The\ Florida\ Airport\ Tape.flac 
ARTIST=Frank Zappa
$ metaflac --export-tags-to=- 02.\ Once\ Upon\ A\ Time.flac 
$ metaflac --export-tags-to=- 03.\ Sofa\ #1.flac 
TITLE=track 1
ARTIST=Frank Zappa
ALBUM=You Can't Do That On Stage Anymore, Vol. 1, Disc 1
DATE=1988
TRACKNUMBER=03
GENRE=Rock
DESCRIPTION=Track 3
COMMENT=Track 3

From track 1 only the artist is filled. Title, album and tracknumber are missing.
From track2 none of the tags is filled, so nothing is returned
Track 3 is titled 'track 1'.

OK,
I suppose all the code should be re-written.
Could you please provide again the list of mandatory tags for mp3 and flac?

For mp3:

Code:
Album
Artist
Title
Track

For flac:

Code:
ALBUM
ARTIST
DESCRIPTION
TITLE


Are those lists correct?

Yes. Indeed. If there is no id tag in the mp3 all properties except 'Track' are in the output and filled with spaces. The property 'Track' isn't in the output at all.
But if there is an id3 tag, but an empty one, the property field IS in the output and has value the value '0'.

With FLAC it's more clear. Only non-empty properties are in the output.

So for mp3 the check should be like:
If title is empty(=filled with spaces) or contains unknown or track
or if artist is empty(=filled with spaces) or contains unknown
or if album is empty(=filled with spaces) or contains unknown
or if the value of the is '0' or the property track is not available
then report this file

For flac:
If title is not available or contains unknown or track
or if artist is not avaliable or contains unknown
or if album is not available or contains unknown
or if track is not available
then report this file

If no property at all is filled metaflac returns nothing at all.

Hmm.. that's really a lot of checks.

Given how the requirements evolved, I decided to go for portable solution.
Check this for mp3 files:


Code:
find . -type f -name '*.[Mm][Pp]3' -exec id3 -Rl {} + |
  awk 'BEGIN {
    mp3n        = split("album artist title track",       mp3_tags)
    flacn       = split("album artist title description", flac_tags)
    ignorepatt  = "^ *(unknown|track *[0-9]*)* *$"    
    }
  /^Filename/ {
    if (fn) {
      for (i = 1; i <= mp3n; i++) {
        if (tolower(tags[mp3_tags[i]]) ~ ignorepatt) {
          invalid_tags[mp3_tags[i]] = tags[mp3_tags[i]]
          f || f++
          }
        }
      if (f) {
       print fn, "has missing/invalid tags:"
        for (t in invalid_tags)
          printf "%s -> %s\n", t, invalid_tags[t]
        }      
      }    
    split(x, tags); split(x, invalid_tags)
    fn = $2; f = x
    }
 { 
    tags[tolower($1)] = $2
    }
  END {
      for (i = 1; i <= mp3n; i++) {
        if (tolower(tags[mp3_tags[i]]) ~ ignorepatt) {
          invalid_tags[mp3_tags[i]] = tags[mp3_tags[i]]
          f || f++
          }
      if (f) {
        print fn, "has missing/invalid tags:"
          for (t in invalid_tags)
          printf "%s -> %s\n", t, invalid_tags[t]
          }            
        }  
      }' FS=:

P.S. Ignore the flac part for now.

Wow. All that in just one tiny line of commands. Smilie

This one does work perfect.
Nice output. Works perfectly on my test dir, so I did a run on my collection... I discovered I've really a lot of retagging to do on mp3. Smilie
I hope my flac collection is in better condition. Smilie

Oh... ik overlooked something in the flac specs you posted. The tags to look for are:
Code:
TITLE
ARTIST
ALBUM
TRACKNUMBER

example output:
Code:
$ metaflac --export-tags-to=- 03.\ Sofa\ #1.flac 
TITLE=track 1
ARTIST=Frank Zappa
ALBUM=You Can't Do That On Stage Anymore, Vol. 1, Disc 1
DATE=1988
TRACKNUMBER=03
GENRE=Rock
DESCRIPTION=Track 3
COMMENT=Track 3

DESCRIPTION is just the same as COMMENT. 'Track 3' is just filled in the comments. Has really nothing to do with the value of TRACKNUMBER.

---------- Post updated at 06:55 PM ---------- Previous update was at 06:20 PM ----------

And here is proof. I just changed the comments.
Code:
$ metaflac --export-tags-to=- 03.\ Sofa\ #1.flac 
TITLE=track 1
ARTIST=Frank Zappa
ALBUM=You Can't Do That On Stage Anymore, Vol. 1, Disc 1
DATE=1988
TRACKNUMBER=03
GENRE=Rock
