How to list directory contents?

To list the contents of a directory in a Linux terminal, you can use the ls command. Here are some common usages:

1. Basic listing:

   ls

2. Detailed listing (shows file permissions, sizes, and modification dates):

   ls -l

3. Including hidden files (files that start with a dot):

   ls -a

4. Detailed listing including hidden files:

   ls -la

5. Listing with human-readable file sizes:

   ls -lh

You can combine options as needed. For example, ls -la will give you a detailed list of all files, including hidden ones.
