Which of the following commands is used to remove files with confirmation prompt from the user file system which have neither been accessed nor modified i the last one year ?
Correct answer: D. find /user/* \(-mtime + 365 - a - atime +365 \) - OK rm {} \;
- A. find -mtime +365 | rm
- B. grep (/usr/*) - mtime + 365 | -ok rm
- C. find -name - mtime + 365 / - ok rm
- D. find /user/* \(-mtime + 365 - a - atime +365 \) - OK rm {} \;
Explanation
The find expression combines -mtime +365 and -atime +365, so both modification and access must be older than one year; -ok rm asks for confirmation before deletion. The other choices either omit one condition or use invalid commands and syntax.
