質問 2：
What parameter of ls prints a recursive listing of a directory's content? (Specify ONLY the option name without any values or parameters.)
正解：
ls -R Explanation The -R parameter of the ls command prints a recursive listing of a directory's content, meaning that it will list not only the files and directories in the current directory, but also the files and directories in all the subdirectories12. For example, if you have a directory structure like this:
/home/user/dir1file1file2dir2file3file4
You can use the command ls -R /home/user/ to list all the files and directories recursively, and the output will look like this:
/home/user/: dir1 dir2
/home/user/dir1: file1 file2
/home/user/dir2: file3 file4
The -R parameter is also known as the --recursive option, which is the long form of the same parameter12.
You can use either -R or --recursive to achieve the same result.
