4. The following command will remove all folders on the following path: /a/b/c/d. note that there are files in those folders.

Question

a) rm /a -r
b) rm /a/b/c/d -r
c) rmdir /a/b/c/d
d) rmdir -p /a/b/c/d

Answer 1

The correct answer is b) rm /a/b/c/d -r.

This command will remove the directory /a/b/c/d and all its contents, including files and subdirectories. The -r option is used to recursively remove all files and directories within the specified directory.

Option a) rm /a -r would remove the entire /a directory and all its contents, including /a/b/c/d, but it would also remove any other files or directories within /a.

Option c) rmdir /a/b/c/d would only remove the directory /a/b/c/d if it is empty. If there are any files or subdirectories within /a/b/c/d, this command would fail.

Option d) rmdir -p /a/b/c/d would remove the directory /a/b/c/d and any parent directories that are empty. However, if there are any files or subdirectories within /a/b/c/d, this command would fail.
