I installed TeX Live 2013 from CTAN by following the instructions here: How to install "vanilla" TeXLive on Debian or Ubuntu?
And it's all working very nicely. However, what I didn't do was purge the original TeX from my Ubuntu 12.04 system. The command
dpkg --get-selections | grep tex
shows a vast panoply of installed TeX packages. Now, suppose I entered:
apt-get purge tex*
Would that remove just the original TeX packages installed from the Ubuntu repositories, or would it, since my fiddling with
equiv, kill the new TeXlive as well?
I don't want to experiment, as I now have TeX and friends up and running as I like, and I don't want to have to do it all over again!
