This works by passing the output of the glob to the function and then counting the number of arguments.
**CAVEAT:** When the glob does not match anything (empty directory or no matching files) it is not expanded and the function returns `1`.
**Example Function:**
```sh
count() {
# Usage: count /path/to/dir/*
# count /path/to/dir/*/
printf '%s\n' "$#"
[ -e "$1" ] \
&& printf '%s\n' "$#" \
|| printf '%s\n' 0
}
```
