I need to provide a detailed list of files in a directory in **descending** order of the **file size**. only to **include 10 files** in my output. I **can not include sub directories** in my output. I'm having the problem with the last part, "not including sub directories" here is what I have so far but I'm stuck on excluding subdirectories. Also if you could look at the below command to advise if this is correct

```
de@Classbox:~/LI_1/etc$ ls -lh -S | sort -r |head -10

```

I know if i use `grep -v d` it will exclude directories but I need it to exclude subdirectories.
