I am following this post to install vanilla texLive and don't know what to do with the following instructions:
Create the following PATHs in your manpath, infopath and PATH for finding your new installation in TeXLive 2017
export INFOPATH=$INFOPATH:/usr/local/texlive/2017/texmf-dist/doc/info export MANPATH=$MANPATH:/usr/local/texlive/2017/texmf-dist/doc/man
Would you help me? I don't know where to put those lines.
