Please share your inputs on the following scenario.

Unix Path 1.

Permissions for /source/dir1/test.txt are 

-rw-rw----+

Scenarios

Case 1: When this file is copied from Windows Explorer to the path /source/dir2

permissions become read only for the group:

-rw-r----+

getfacl text2 shows mask as

r--

Case 2: Unix cp command is used to test.txt from /source/dir1/ to /source/dir2/

permissions for test.txt in dir2 are 

-rw-rw----+.

getfacl text2 shows mask as

rw-

For both the scenarios same userid belonging to the same unix group is used.

Do you know why permissions are different ?

  1. Is there a trigger or a way that unix server knows that file is being copied by an environment external to unix. ?
  2. Since the userid and the group is same is it an ACL setting/rule ?
  3. If 2 is yes, what is it ?

Any help is appreciated.

They work with different umask settings.
