How does the -n rz option in the nl command affect the formatting of line numbers?

The -n rz option in the nl command affects the formatting of line numbers in the following ways:

• -n specifies that you are customizing the numbering format.
• r indicates that the line numbers should be right-aligned (this is the default behavior).
• z adds leading zeros to the line numbers, ensuring that they have a fixed width.

For example, using nl -n rz config.txt will produce output where line numbers are right-aligned and padded with leading zeros, making them easier to read and consistent in width. This is particularly useful for sorting or further processing the output.
