MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Explanation: Like mkdir command, we can delete multiple directories using one shot of rmdir command. While deleting directories and subdirectories, a reverse logic is applied i.e. first the subdirectories or the child directories are removed and then their parent directories.

Detailed explanation-2: -The rmdir command removes the directory, specified by the Directory parameter, from the system. The directory must be empty before you can remove it, and you must have write permission in its parent directory. Use the ls-al command to check whether the directory is empty.

Detailed explanation-3: -To delete multiple files at once, simply list all of the file names after the “rm” command. File names should be separated by a space. With the command “rm” followed by multiple file names, you can delete multiple files at once.

Detailed explanation-4: -Clarification: cd (change directory) command is used for moving around the file system. cd command is usually invoked with a argument. After invocation, it changes the current directory to the directory specified as argument. Cp command is used for copying files while rm command is used for deleting files.
