Following is the scenario. There are multiple files in a directory created by users belonging to same unix group.
Unix Group: Prod. User in Prod Unix Group: User1 User2 User3.
All 3 users have same privileges.
Scenario 1 If user3 wants to become owner of the files created by user1 and user2 by preserving datetime stamp what is the command user3 needs to execute?
Scenario 2 Can user copy/move the same file in same directory by preserving datetimestamp? What is the command for it?
Scenario3: I tried touch command for the file created by User1. Ownership is changed however timestamp is updated too. Is there a way that timestamp remains the same using touch command?
Thanks.
