The purpose of ReadDir is to list the contents of a *directory*.
That is: if stat tells you that the entry is a directory, then you can
ReadDir to list the files inside that directory. This is one way to
traverse a directory tree recursively.
ReadDir doesn't work if the entry is a file, but stat will tell you other
things you may want to know about the file (such as its size). If you want
to read the file contents, then open it and read it as normal.
I'll check, but I'm able to call os.ReadDir on an individual file on Ubuntu

That shouldn't work. For me, with go 1.16 under Ubuntu 18.04:
--------
package main
import (
"fmt"
"os"
)
func main() {
_, err := os.ReadDir("readdir.go")
if err != nil {
fmt.Printf("Error: %v\n", err)
os.Exit(1)
}
}
--------
Gives:
Error: readdirent readdir.go: not a directory
