You would be better to create the files like this:-
Code:
cd imagesdir
ls | cut -f1 -d "." > ../listA.lst            # Important not to write to the current directory
cd ..

cd wavsdir
ls | cut -f1 -d "." > ../listB.lst            # Important not to write to the current directory
cd ..

What you have done is to write the contents of all the files into listA.lst & listB.lst respectively rather than the list of filenames.

The above approach has the cut in place to trim off the end of each file name, so you should end up with two files that list what would be the common parts of the names that you are looking to compare. This assumes that there are no files with a dot in the part you want to compare.

Using the grep commands would then list the common (or missing) files that you are interested in and you can build your required commands from in a loop, obviously adding back on the .png or .wav as appropriate.


Does that help?

img-png

img-png(3tk)															      img-png(3tk)

NAME

       img-png - Img, Portable Network Graphics format (png)

SYNOPSIS

       package require Tk

       package require img::png  ?1.3?

       image create photo ?name? ?options?

DESCRIPTION

       The  package  img::png  is a sub-package of Img. It can be loaded as a part of the complete Img support, via package require Img, or on its
       own, via package require img::png.

       Like all packages of Img it does not provide new commands, but extends the existing Tk command image so that it supports  files	containing
       raster images in the Portable Network Graphics format (png). More specifically img::png extends Tk's photo image type.

       The  name  of  the new format handler is png.  This handler provides new additional configuration options. See section PNG OPTIONS for more
       detailed explanations.

       All of the above means that in a call like

       image create photo ?name? ?options?

       [1]    Image data in png format (options -data and -file) is detected automatically.

       [2]    The format name png is recognized by the option -format.	In addition the value for the option is treated as list  and  may  contain
	      any of the special options listed in section PNG OPTIONS.

PNG OPTIONS

       The  handler  provides no true options at all, but accepts pairs of keys and values when writing a PNG file. Each pair will be written as a
       named text chunk where the key provides the name of the chunk and the value its contents.  For example
	   png Author <name> Title <title> Description ...

TRANSPARENCY

       If you want to write images to disk which contain transparency information (e.g. PNG with alpha channel) you need at least Tk 8.3.
