This is why I might cut the first 64 digits, because it looks a bit too nasty with the sha256sum, imagine sha512sum.

Code:
f888084c9ee5af98bb46df1c059b8cc2bcc4d9c43691e139f5bce44c64926e3a  ./drum/soundz4/GLASS CAVES – Out Of Control.mp3

as always learning

@Aia for heavens sake, sed coming up......yeah, I will train this....thanks, I will report later.

harsh.....

@Aia The quadcore works a lot with the xargs -0 version right now. I just started to read the first chapter of 63 for sed, so sorry, that this is one of the commands I hoped to avoid until now. First try results in one single file, the destination.mp3 in this case. hm....

@Don Cragun
one directory, 252 subdirectories, nearly 5000 tunes, different versions, kbps, length, put them in one folder.
My script from last year, well lets call it a snippet of a script, was hopping from one directory as the outset to move (cp) to destination. Then I took the destination to hop to the third new directory and so on. Surely not a hundred times, but it got a result of 30GB for snippets of tunes, one second of hihat, 3 seconds of openhihat, all together 26k files, or items. Therefore I used this construction

Code:
find /home/origin -type f -exec sha256sum {} \; | sort -k 64 >  /tmp/runner;txt | cp -nr /home/origin /home/destination && cat  -n /tmp/runner.txt | cut -d " " -f1; exit 0;

and guess what, it worked.

And I am aware, that the real 19 inch server rack is not sorted like this, they would put any file listed in alphabetical order, for each letter one drive, may even for different formats (.jpeg or .png) different mirrors. It is just to have it in one directory and later on on a pluggable drive.

@Aia It stopped after 575 songs, unable to call stat for "-" (no underliner), could not find directory. Running now version two, with sed. That goes well as root, I'll try it as well as user. Resulting in 4429 tunes, 22 GB. Orignally it was 22.9 GB. Now I could work with diff or midnight commander.

NAME
tagmp3 - manipulate ID3v1 tags SYNOPSIS
tagmp3 [ -n ] mode [ format ] [ file ] ... DESCRIPTION
tagmp3 allows you to set and remove ID3v1 tags from mp3 files. Additionaly move mode can be used to move mp3 files according to their ID3v1 tag. An ID3v1 tag is a chunk of extra informations such as artist name, album and genre. ID3v1 tags are displayed by most mp3 players. MODE
show show file's ID3v1 tag. set sets file's ID3v1 tag according to format. move move file to a destination based on FORMAT. del remove file's ID3v1 tag if any. list displays numeric music genres along with their meaning. -h print a (not so) short help message. -v print version and exit. OPTIONS
-n Show what will be done, don't alter any file. FORMAT STRING
The format string is a character string composed of zero or more directives: ordinary characters (not %), which are not interpreted and conversion specifications, each of which results in the corresponding ID3v1 tag field substitution. Each conversion specification is introduced by the character %. The following lines describes each conversion specification along with its associated ID3v1 field. Special sequence %% is substituted with a single %. %A Artist Name %a Album Name %t Song Title %T Track Number %y Year %g Genre %c Comments format string for set mode For set mode the format string is a list of ID3v1 fields followed by a ':' (next chars are the field value) or a '?' (ask user for field value) example: tagmp3 set "%A:Pink Floyd %a:The Wall %t? %T?" *.mp3 For each mp3 of this directory, sets the artist name to Pink Floyd and the album to The Wall. For each file ask for the title and the track number. Leave the other fields untouched. Be aware that genre field require a numeric value. Known genres can be dis- played with the list mode. format string for move mode The format string is the destination path where each field identifier is substituted with the tag value. example: tagmp3 move "/home/foo/mp3/%A/%a/%T-%t.mp3" *.mp3 with the set example above will move all mp3 to "/home/foo/mp3/Pink Floyd/The Wall/{track}-{title}.mp3" If you prefer the "flat" naming scheme, you will use something like tagmp3 move "%A-%t.mp3" *.mp3 NOTES
move mode never overwrite files. move mode creates intermediate directories specified in the format string. Each directory creation is to be confirmed by the user. ID3v2 tags are not supported so far. If a file can't be moved ( wrong file type, ID3v1 tag absent or blank field , ...) then it is left untouched. Fake mp3 (i.e. Wave file with .mp3 extension) are moved into "fake-mp3/" directory in move mode. set mode refuses to tag them since this would add noisy artifact at the end of the song. BUGS
Plenty of :) For move mode, source and destination must reside on the same file system / partition. AUTHOR
