How do you verify the contents of a directory in the command line?

To verify the contents of a directory in the command line, you can use the ls command. This command lists the files and directories within the specified directory.

Here are a few examples:

1. To list the contents of the current directory:

ls

2. To list the contents of a specific directory, for example, backup:

ls backup/

3. To get more detailed information about the contents, including permissions, owner, size, and modification date, use the -l option:

ls -l

4. To include hidden files (those starting with a dot), use the -a option:

ls -a

You can also combine options, for example:

ls -la

This will provide a detailed list of all files, including hidden ones.
