I have made a long list of macros that I have put in a style file. I have been working with this same style file for many years now. I would like to put it somewhere in my TeX tree, so that I don't have to copy it each time to a new location. Furthermore, each time I add a new macro I have to add it in all the copies...
Is there some folder in /var/bin/share/local/texmf/etc/opt or whatever where I can just put the file and then forget about everything? I don't like to have the style file in my home directory (I don't want to see it).
I don't know anything about the TeXMF tree, and I would like to keep it that way.
I use Linux Mint (very similar to Ubuntu), and I installed LaTeX via apt-get install texlive. I have Google'd for the question, but I always get very complicated and unsatisfactory responses.
