I'm using tex-live on a Ubuntu machine. I got a customized graphics.cfg file (configuration file for the graphix package) that I'd like to use as default on my system.
I've tried to locate the graphics.cfg used on my system:
but I got many results:
/etc/texmf/tex/latex/config/graphics.cfg /usr/share/doc/texlive-doc/latex/latex-graphics-companion/inputs/graphics.cfg /usr/share/doc/texlive-doc-en/latex/latex-graphics-companion/inputs/graphics.cfg /usr/share/texlive-base/graphics.cfg
Which file should I substitute with the desired one? Thanks for the help
P.s. I know that I might modify the one in my local tree, but I'm writing a tutorial and would like to write a section explaining how to modify it system-wide and user-wide.
