TeX - LaTeX Stack Exchange is a question and answer site for users of TeX, LaTeX, ConTeXt, and related typesetting systems. It's 100% free, no registration required.

I'm trying to write a script (Perl) for the general public which would need to have a list of all installed TeX files of a certain type, e.g. .sty and/or .cls files or only plainTeX files (.tex), depending on the used options.

I know I can search for specific files using the kpsewhich program, but it seems to have no 'list all' mode (which is understandable). My second idea was to parse all ls-R files which should work, but would be more work.

Is there a way to get all TeX source files or only the ls-R files from kpsewhich or another tool?

At best this should work for both TeX Live and MikTeX on all supported operation systems. However, my main target is TeX Live under Linux. As fall-back solution I would hard code the default paths and allow the user to change these using a configuration file.

This is not my area of knowledge, but MacTeX provides a program called TeX Live Utility which is a GUI for tlmgr which can list all the installed packages: tug.org/texlive/doc/… Maybe you could utilise its approach. –  Harold Cavendish Jul 22 '11 at 17:03
    
Or you could probably use shell find /usr/local/texlive -name "*.sty". –  Harold Cavendish Jul 22 '11 at 17:14
    
Thanks @Harrold, I know about such possibilities. I'm trying to avoid them and #use the official tools to get the official paths. –  Martin Scharrer Jul 22 '11 at 17:20
    
You might want to use the fact that in modern TeX distributions, texlua is a standalone lua interpreter. –  mbork Jul 22 '11 at 17:28
    
@mbork: So call texlua with Lua code from inside a Perl script??? Or are your trying to tell me to not use Perl at all but Lua? –  Martin Scharrer Jul 22 '11 at 17:33

here is a shell script, which finds all bst,sty, and cls files which are available with kpsewhich.

 #!/bin/sh
# file: ~/bin/TeXFiles.sh
# lists all available 
# TeX class files   -> option cls 
# TeX style files   -> option sty
# bibtex style files    -> option bst
#
# with the help
# of kpsewhich and creates a 
# bstFiles.lst, clsFiles.lst, styFiles.lst
# without any parameter all files are created.
