* Checking differences between two files and patching

Checking differences between two files and saving in a new file ("diff.patch"):

#+begin_src bash
  diff -u new_file.org old_file.org > diff.patch
#+end_src

Using ~patch~ to include the differences in the second file to update the document:

#+begin_src bash
  patch -u old_file.org -i diff.patch
#+end_src
