Shell scripting & ID3 tags

[blazemore]

I know next to nothing about shell scripting.

Is it possible to feed a script a folder, and have it go through (including subdirectories), renaming every file it finds according to its ID3 tags:


/home/user/Music/%Artist/%Album/%Title

While keeping the extension the same

Why not easytag (http://easytag.sourceforge.net/), audio tag tool (http://pwp.netcabo.pt/paol/tagtool/) and exfalso ? The tools can rename files/folders based on ID3 tags.

Thunar (bulk rename) can also do this.

Also amarok can do it (both 1.4 and 2.0 i think).

Here is a one-liner BASH command using GNU's AWK processor and the id3v2 (http://sourceforge.net/projects/id3v2/) tag editor. I don't think id3v2 works with OGG tags (there are other command line tools which support both) but this was more to provide a proof-of-concept for writing your own script -- which should probably have some error checking :) and handle spaces in the source path better (I'm converting them to underscores).


FILE=/some/dir/some.mp3 ; BASE=$(basename $FILE) ; EXT=${BASE##*.} ; TGTDIR=$(id3v2 -R $FILE | awk 'BEGIN { FS=": "; OFS=""; } /^TP1/ { $1=""; gsub(" ","_"); artist=$0; } /^TAL/ { $1=""; gsub(" ","_"); album=$0; } END { print artist "/" album "/" }') ; mkdir -p $TGTDIR ; TGTBASE=$(id3v2 -R $FILE | awk 'BEGIN { FS=": "; OFS=""; } /^TT2/ { $1=""; gsub(" ","_"); title=$0;} END { print title }') ; mv $FILE ${TGTDIR}${TGTBASE}.$EXT

Amarok 1.4 does this very well.
