What parameter of ls prints a recursive listing of a directory's content? (Specify ONLY the option name without any values or parameters.)
Suggested Answer:
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. References: * Use ls Command Recursively - Linux Handbook * How to List Files Recursively in Linux command line
