Each file in Linux has three time stamps, which record the last time that certain actions were performed on the file:
[a] access (read the file’s contents) – atime (days) OR amin (minutes)
[b] change the status (modify the file or its attributes) OR ctime (days) / cmin (minutes)
[c] modify (change the file’s contents) – mtime (days) OR mmin (minutes)
- -amin +720 means you are looking for a file accessed 12 hours (720 minutes) ago.
- -amin -720 means less than 12 hours (720 minutes).
- -amin 720 If you skip + or – it means exactly 12 hours (720 minutes).
