texcount

Count words in TeX documents omitting macros. Note: if the TeX document uses \include or \input and you want to count the included files, texcount must be run in the directory of the root TeX file. More information: https://app.uio.no/ifi/texcount/howto.html.

• Count words in a TeX file:
  texcount {{path/to/file.tex}}
• Count words in a document and subdocuments built with \input or \include:
  texcount -merge {{file.tex}}
• Count words in a document and subdocuments, listing each file separately (and a total count):
  texcount -inc {{file.tex}}
• Count words with verbose output:
  texcount -v {{path/to/file.tex}}
