PRETag (or Perl Regular Expression [ID3] Tag [Tool]) allows you to tag your MP3
files using Perl regular expressions. Who would have thought! Run with -h for
all the information you need, including examples.
For your convencience, I've pasted the output of pretag -h here so you don't
have to install it to see if it is what you're looking for.
Usage: /home/jkramer/scripts/pretag <-p pattern> [optional stuff] [bunch of MP3 files]
-p | --pattern=
Looking at the usage line above, you might have thought, "hey, -p is the
only non-optional argument, so it must be important," and you're right!
This whole script is about that pattern, because it lets us gather track
information from file names using a regular expression. This is why you
need to know (Perl) regular expressions to use this tool. The wanted
information is extracted from the file names using "named groups" or "named
capture buffers". Check perlre(1pm) and the examples below for details.
-v | --verbose
Print lots of information about what's going on.
-h | --help
Print this help text and quit.
-d | --dry-run
Don't actually do anything (only useful with -v to see what would be done
if you had not used -d).
-c | --title-case
Try to fix the title case of found tags.
-N | --noise=
Use this to define a regular expression that matches characters and strings
considered line noise. E.g., some people think it's funny to distribute
files like this "09-bloodhoundgang-_the_ballad_of_chaseylain-ysp.mp3"; use
"-N '|-ysp'" to fix it.
-z | --zero-pad=
Use this to fill the track number with zeros to the given width. For
example, the original track number 1 would become 001 with -z 3. Only
affects the generated file name (when -r is given), not the ID3 tag.
-r | --rename=
Rename the file using the given file name format. The format should like this:
"
