Usage: tagall.sh [option]
option is either the file format e.g. ogg for batch processing files of a particular type, or a file name if processing a single audio file. (Or -h / --help for help.) When omitted all compatible audio files in the current directory are processed.
When batch processing all files will have the same album, artist, date and genre tags. Track and title can be derived from the file name by entering y when prompted. (Track only works if the filename starts with a number.) Alternatively press i to enter track and title information for each file.
Pressing ENTER whenever prompted will skip ahead retaining current tag if one exists.
Enter del to delete current tag.
