Hello, I've added a small blockquote below the description to indicate that this method of accessing an indefinite number of function arguments has been superseded by the use of the spread operator via rest parameters for ES6+ compatibility.

+# Get Word Count For All Files In Git Repo
+
+As part of gathering numbers for [A Decade of TILs](), I wanted to get an word
+count of all the TIL markdown files I've committed to this project over its 10
+year history. By using `git ls-files` with a pattern, I can get a list of all
+file names. Then with `xargs` I can pass that entire list to `wc -w` which
+gives a word count of each. The final line that `wc -w` outputs is a sum total
+of all the file word counts. Lastly, piping that through `tail -n1` gives me
+just that last total count line.
+
+```bash
+$ git ls-files "*/**.md" | xargs wc -w | tail -n1
+  206816 total
+```
+
+Since the `tail -n1` obfuscates what the `wc -w` is doing, here is what that
+looks like before that final pipe.
+
+```bash
+$ git ls-files "*/**.md" | tail -n3 | xargs wc -w
+     115 zsh/add-to-the-path-via-path-array.md
+     190 zsh/link-a-scalar-to-an-array.md
+     214 zsh/use-a-space-to-exclude-command-from-history.md
+     519 total
+```
+
+I can even clean up the final output a bit more with `awk`:
+
+```bash
+$ git ls-files "*/**.md" | xargs wc -w | tail -n1 | awk '{print $1}'
+206816
+```
