How to list files?

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

1. Basic listing:

   ls
   

2. List with detailed information:

   ls -l
   

3. List all files, including hidden files:

   ls -a
   

4. List files with human-readable sizes:

   ls -lh
   

You can combine options as well, for example:

ls -la

This will list all files, including hidden ones, with detailed information.
