What is the difference between find options -cmin and -amin?

Question

Reading Finding the files which are not accessed/modified in last 30min? I'm puzzled by the difference between change time and access time.

Could you elaborate on the difference and source your statements?

Answer 1

Based on Find the Time of Access, Change & Modify File in Linux & Unix:

• Access is referring to the last time the file was read, view or displayed (e.g. more, less) ;
• Modify means when was the last the file content was modified (e.g. vi) ;
• Change term was determined by when was the last meta data of the file been modified (e.g. chmod, chown).
