In order to append the output of Is to a file called bazz, which of the following command lines would you use?

The `>` redirection operator sends standard output to a file, but it *overwrites* the file's contents if it already exists, rather than appending.

The `>&` operator (older shell syntax) redirects both standard output and standard error to a file, but it also *overwrites* the file's content.

The `&>` operator (modern Bash syntax) redirects both standard output and standard error to a file, but it also *overwrites* the file's content.

The `>>` redirection operator (assuming `Is ?bazz` is a typo and should be `ls >> bazz`) is used to append the standard output of a command to a specified file. If the file exists, the output is added to the end; if it does not exist, the file is created. This ensures previous file content is preserved.
