The obvious way to do it is:

1. Find some way to get a list of the files
2. Pipe it into `wc` to count

Classically, this would be `find /path/to/dir | wc`. However `fd` does the same thing with better usability. By default, `fd` will skip "hidden" files and directories (like `.foo`) and will include both files and directories.

Both behaviors can be changed by finding the appropriate CLI arguments in `man fd`. However, if you are in a hurry, there's no need to overcomplicate it:

```
fd | grep -v '/$' | wc
```

`/$` is a regex meaning "ends with `/`" and `-v` is short for `--invert-match`.
