Hello,

maybe you can start with a simple:

#+NAME: hash-from-lisp
#+BEGIN_SRC emacs-lisp
  (shell-command-to-string "git rev-parse HEAD" )
#+END_SRC

#+RESULTS: hash-from-lisp
: 099b6ceee7264832b8e13f1156974b8017e6e4bb

You can hide the result using proper headers or the noexport tag and
then print the result in a verbose way:

The latest commit hash is src_emacs-lisp[:var i=hash-from-lisp]{(format "%s" i)}

or if you enable the shell in babel you can start with:

#+NAME: hash-from-shell
#+BEGIN_SRC shell
git rev-parse HEAD
#+END_SRC

For latex only, I use the following snippets.  This works with gitinfo2
(in debian you need the packages texlive-latex-extra and
texlive-latex-extra-doc).  Sorry for the long lines...

Please note that this will also highlight the dirty status of the repo,
since adding the latest hash for a modified version make little sense.

Best,
Daniele

#+LATEX_HEADER: \usepackage[,missing={Unknown},dirty={-- Uncommited Changes!!!},notags={Unknown},mark]{gitinfo2}


#+LATEX: \renewcommand{\gitMarkPref}{Historical Info}
# NOTE: \gitTags does not work well: it adds a traling ")"
# NOTE: \gitReln takes the latest release, even there are more commits
#+LATEX: \renewcommand{\gitMark}{Version:\space{}\gitTags{}\space{}--\space{}Id::\space{}\gitAbbrevHash\space{}--\space{}Date:\space{}\gitAuthorIsoDate\space{}\gitDirty}


#+BEGIN_SRC emacs-lisp
  (defun update-gitinfo (backend)
    "Update .git/gitHeadInfo.gin"
    (message "Command: %s" (shell-command-to-string "cd `git rev-parse --show-toplevel` && /bin/bash /usr/share/doc/texlive-doc/latex/gitinfo2/post-xxx-sample.txt"))
    (message "Updated gitinfo"))

  (add-hook 'org-export-before-processing-hook #'update-gitinfo)
#+END_SRC
