Which of the following options will be used to display number of blocks used by a file?

Answer & Solution
Correct Answer: Option D
In Unix, the du command is used to estimate file space usage. The -s option, when used with du, displays only a summary of the disk usage, including the total number of blocks used by a file or directory.
So, -s is the option used to display the number of blocks used by a file.
