bash - batch processing folder of files by name
Hello Everyone!!!

I need some help with a shellscript to batch process a folder of files with the imagemagick convert -append/+append command. The folder contains some hundred or thousand of small images in .png format which I would like to join together in order of their filenames. The filenames follow a pattern like this:

File 1: 11.123456_8.043589.png
File 2: 11.123456_9.320411.png
File 3: 12.843211_8.043589.png
File 4: 12.843211_9.320411.png

What I want to do is join all files with the same number in the first part of the filename (before the underscore) with the convert +append command to a row and afterwards join these rows together with the convert -append comand. This could also be a second script, if easier.
I figured out the imagemagick part of this, but as an absolute beginner to shellscripting, I have no clue how to get a appropriate shellscript up and running. I have searched the forum but didn't find anything that worked out for me or pointed me in the right direction. I would really appreciate some help here!

Greetings,

Gerd

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.
