Problem
Listing and sorting directories
Create a Bash script that accepts directory paths as arguments. For each argument, list the contents of each directory with the name of each listed at the top.
If you want to give yourself an added challenge, have your script accept an additional argument, "a" or "d," that sorts the contents of each directory in either ascending or descending order. For even more of a challenge, create a Bash script that sorts the contents of the directories based on an "a" or "d" argument that directly precedes it. In other words, you should be able to sort one directory in ascending order, a second directory in descending order, and so on.
