1. Download the file hhcount.sty and save it (like in your Downloads folder)
2. Navigate to /usr/share/texlive/texmf-dist/tex/latex/
#cd /usr/share/texlive/texmf-dist/tex/latex/
and create a folder named hhcount
#mkdir hhcount
3. Now navigate back to your Downloads folder (or wherever you downloaded hhcount.sty) file and
move/copy the file to the newly created folder.
#mv hhcount.sty /usr/share/texlive/texmf-dist/tex/latex/hhcount
4. Run the texhash command
#texhash
5. Since hhcount.sty is dependent on hhutils0.sty, you need to download it again and like in
the previous steps, create a folder hhutils0 inside /usr/share/texlive/texmf-dist/tex/latex/ and move
hhutils0.sty there. Again run texhash command.
6. Now include \usepackage{hhcount} in your tex file and wherever you need to include tally
marks, use \fcsore{n}, where n is the frequency number. If you need to put a tally mark against 5, use \fcscore{5}, if against 7 use \fcscore{7}. Run LaTeX, and you'll get the tally marks in
your document as
