I am running latexlive, I think everything is installed. How can I check to see if the etoolbox and ifthen packages are installed? I think these packages will solve my problems.

If they are not installed, what is the best way to install them on a Debian environment?

  • We meet again :) If you use the terminal heavily, you can use kpsewhich etoolbox.sty and check the exit code. But don't use ifthen – it's exceptionally out-of-date. Depending on your needs, there are a variety of better tools out there. What exactly are you trying to do? – Sean Allred Jun 3 '15 at 2:31
  • In your shell, try tlmgr info etoolbox or tlmgr info --list etoolbox. – Arash Esbati Jun 3 '15 at 6:22

The quickest way to check if a package is installed is to search for it with kpsewhich {package-name}.sty. So, to check for etoolbox, use

$ kpsewhich etoolbox.sty

If it finds the package, it will output the path (just like normal which). If it doesn't find the package, it will output nothing and have a non-zero exit code.

Perhaps the most direct way to answer the question though would be to try and use the package:


The above will fail if etoolbox cannot be found.

  • Sorry you are right, texlive. Let me check for etoolbox.sty and see. – Gregory West Jun 3 '15 at 2:43
  • As you said, this question is in the wring area. Etoolbox is installed, but the .tex file crashes if I include \usepackage{etoolbox}..... where should I post this ? – Gregory West Jun 3 '15 at 2:59
  • @GregoryWest I can vouch that this answer is correct, so perhaps you should ask your actual question in a new post with a MWE. See also What is the X–Y problem?. – Sean Allred Jun 3 '15 at 3:02

Using the bash command locate in Unix find the texlive directory in your system:

$ locate texlive

Mine is in /usr/local/texlive. Once located you can see all the packages installed in your latex library using ls. In my case:

$ ls /usr/local/texlive/2016/texmf-dist/tex/latex/*/*.sty

Gives me the complete set of packages (sty files) available in my computer with texlive.

Edit: Another purer latex way would be to compile one tex file, call it myfile.tex (with a line \usepackage{my-package}) and open myfile.log to see where is pdflatex loading the package from. In your case finding the texlive path.
