Now the titles have ABCD${TITLE} of which I wanna remove “ABCD”. How do I do this removal? Removing in the sense I wanna delete some chars of it and I don’t wanna remove the entire tag-field.

Anyone knows how to do it? The help file doesn’t say how to do regexp for a modification (existing is only add/remove) on an existing field.

usage: id3 [-1 -2 -3] [OPTIONS] filespec …
-v give verbose output
-d clear existing tag
-t set tag fields
-a
-l (i’th matched `*’ wildcard = %1-%9,%0
-n path/file name/counters = %p %f %x %X
-y value of tag field in file = %t %a %l %n %y %g %c)
-g
-c
-D <filename duplicate tags read from filename
-f rename files according to template
-q print formatted string on standard output
-m match variables in filespec
-R search recursively
-M preserve modification time of files
-V print version info
Only on last selected tag type:
-s set tag size
-E only write if tag already exists
-u update all standard fields
-rTYPE erase all `TYPE’ frames
-wTYPE write a `TYPE’ frameReport bugs to .

I am looking for more detail of these options, for example I don’t undestand about “[-1 -2 -3]“, -q what is the “format” here, etc. Could you please send me this info? Is this utility support extended tags such as “composers”, “lyricists” etc.

Thanks
