How can I display end of line characters using the cat command?

To display end-of-line characters using the cat command, you can use the -E option. This option will add a dollar sign ($) at the end of each line in the output, making it clear where each line ends.

Example:

Here’s how to use it:

cat -E filename.txt

Explanation:

• Replace filename.txt with the name of the file you want to display.
• The -E option will show a $ at the end of each line.

Sample Output:

If filename.txt contains:

Hello, World!
This is a test file.
It has multiple lines.

The output with the -E option will look like this:

Hello, World!$
This is a test file.$
It has multiple lines.$

This makes it easy to identify the end of each line, which can be particularly useful for troubleshooting formatting issues or trailing spaces.
