Why compiling LaTex examples require 'sudo'?

Postby erwann » Thu Aug 25, 2016 4:17 am

Why are TexLive's doc files owned by root? Would it be a good idea to \chown them to a non root user?

  1. texmf-dist my-mac$ ls -ld doc/
  2. drwxr-xr-x 49 root staff 1666 Aug 24 19:31 doc/
  3.  
  4. $echo $PWD
  5. /usr/local/texlive/2016/texmf-dist/doc/latex/lettre
  6.  
  7. $ pdflatex letex1.tex
  8. This is pdfTeX, Version 3.14159265-2.6-1.40.17 (TeX Live 2016) (preloaded format=pdflatex)
  9. restricted \write18 enabled.
  10. entering extended mode
  11. ! I can't write on file `letex1.log'.
  12.  
  13. $sudo pdflatex letex1.tex
  14. Password:
  15. This is pdfTeX, Version 3.14159265-2.6-1.40.17 (TeX Live 2016) (preloaded format=pdflatex)
  16. restricted \write18 enabled.
  17. entering extended mode
OS X 10.11
pdfTeX 3.14159265-2.6-1.40.17

Installing TeX Live in your home directory would have made the whole installation yours, no need for the super user.

Everything in /usr/ is protected to be accessed only with sudo rights. And that is a good thing. You should keep it that way ;-)

You should never create your own documents, no matter if LaTeX or anything else in /usr/. Always do it somewhere in your /home/ directory (or a subdir of it).
The smart way: Calm down and take a deep breath, read posts and provided links attentively, try to understand and ask if necessary.
